USB data transfer not working. - Xiaomi Mi A2 / 6X Questions & Answers

So i bought a used A2 for 5500 INR.
At first i thought it was a bargain but soon it turned out to be a nightmare.
The phone is full of bugs.
Worst one is that the phone only charges through the usb port. No data transfer of any sort. like an old nokia pin charger.
OTG doesn't work. It doesn't connect to the PC.
Whenever I plug in the OTG/connect it to pc, the usb options are all greyed out (same in the developers options default usb preference).
I can't even use Gcam now bcoz the PC doesn't recognise the device at all, so can't enable Camera2api, can't root, can't install ROMS... can't even buy a new phone cuz i have no money ???
turns out my phone also have the slow Emmc issue ?....read speeds are okay but write speeds are very slow... specially Random write (~10mBps).
I read many people have faced this issues. All those Posts are old, has anyone found a solution.

[Q] USB Connection Issues

I have an issue with my PC not recognizing my Captivate. When I plug in the USB cable to my PC, I can choose to activate USB mode and it prompts me to mount the drive, I say yes but nothing shows up in My Computer. I was able to do all this fine just a few days ago.
I have uninstalled/reinstalled the drivers. I installed Samsung Kies and it doesn't recognize the phone. I tried my phone on another PC and it won't show up there either. I've factory wiped the phone twice now.
Is it a problem with the phone or is there something I can do to get this to work?
I'm having the same issue. Did you get this resolved & if so, how? Tried both ports on my MB Pro & work PC...tried Samsung cable & another USB cable. Debugging is on.
Try Settings -> Applications -> USB Settings -> (select) Mass Storage
I found that when my captivate was set to Kies my computer wouldn't pick it up.
Mine was set to ask on connection. Tried mass storage mode (debugging off) & no dice. Back to ask on connection with debugging on, and still nothing. I've tried all 3 USB ports on my work laptop and both on the MB Pro. Any other ideas?
Did u try enabling "debug mode" and seeing if the PC recognizes it.
The main issue is usually your USB cable. I had the same issue. You need to find an OEM mini usb cable for it to work properly. The one that came with my phone works fine, but when i went to ATT and bought one for my work, it only lets you charge the phone and does not put your phone into USB connection mode.

The ones from MonoPrice work for me and they were like $1.50
Diablo: Been in debugging mode most of the time trying to get it to work. Main issue is getting my personal MB Pro to recognize, so I won't be able to check/tinker much until after work tonight.
cajuntigerbait: I've been using the provided Samsung cable – tried a work Blackberry cable (works fine with my work BB) to no avail as well.
Will update tonight. Any tried & true methods for cleaning the phone port while I'm at it? Thanks for the quick responses, everyone

Note 5 USB Port Not Working Except for Slow Charging

I have researched the issue of my Note 5just being able to slow charge via USB, and not be able to do anything else. I have tried all the proposed solutions I found, but can not fix the issue. The things that I have noticed to not work are:
Fast Charge: Cable and USB charging is detected, but cannot fast charge. I have tried the same charger and cable on other S7 edge, and it able to Fast charge. Fast charging is enabled in the battery menu
Connect to PC: Whenever connected to any PC, the PC shows “USB Device Not Recognized." I have the latest version of Smart Switch and the latest drivers. I have tried multiple computers and windows 7, 8 and 10. I have also tried to connect to the PC when the phone is in Download and Recovery mode and get the same error.
Connect to any OTG peripheral: Nothing is detected by the Note 5. Same cable working on other device.
Connect to Gear VR: When connecting to Gear VR, it gives the chime, the black screen with the little x in the corner appears for a second and then it goes back to the home screen.
What I have tried to do to fix:
Different cables/chargers/USB ports
Checked if any of the 5 pins are broken in the cable
I have lifted the tongue of the charging port in the phone via tooth pick
Done a factory reset
Any insight on this issue would be appreciated.
Thanks

Have you tried different 2A charging bricks? A regular 1A charger would still take a long time to fully chargeNote5.
You could also be looking a bad USB-port or a faulty battery, both of which would be covered under warranty provided no large physical damage is evident on your device.
Thanks for the reply. I have tried the original Samsung charger, 2A, 1A, and 0.5A charging bricks, but the phone shows either Cable or USB charging.
About the faulty battery, will that cause the PC and other peripherals to not detect the phone?

Same happened to me two days ago. I restored an old backup, done a factory reset and restored my actual rom again and problem solved. Idk what the problem was related to. Try wiping cache again, maybe it helps.

I have done a wipe from TWRP, but the issue was not fixed. I can not change ROMs etc as I can not connect the Note 5 to the PC via USB cable, even in TWRP.
Was your phone just not Fast Charging, or it wasn't being recognized by the PC, etc.
Thanks
Actually y have the same problem, unfortunately I don't have root access.
Try the app called USB host check, maybe they can help you.
Is not possible to me because the PC don't detect the phone connection and obviously I can't make the root.

I have the same issue tried the same fixes. No luck. Have you found a solution please?
I ultimately had to change the motherboard. Changing the charging port did nothing.
However, I suspect it was a corrupted firmware. If you can somehow flash a latest stock firmware and check, that would be great.
In trying to fix the firmware I had corrupted Stock ROM. Since I could only use WiFi to transfer files via WiFi FTP type apps, and I didn't have a working ROM backup on my phone, after the Stock ROM was corrupted, I could not upload any new files to flash with TWRP so I had to change the motherboard.

If you see the "USB Device Not Recognized" message when you connect to the PC, then I think the charging port is fine. It is some issue with the firmware as phone is not able to provide the correct PID and VID to the peripheral devices to identify itself. The charging port and its circuit doesn't hold that info. If possible, try to flash a stock firmware from TWRP as ODIN will not work (I am not aware of the exact procedure). Just MAKE SURE you have make a backup of your current setup and leave it on the phone as if you have an unsuccessful flash, you will not be able to use ODIN or ADB as your cable will not work.

I've messed up, I've already clear the cache, Dalvik , Data and System without having backup Rom/firmware in my internal memory. I've try using OTG. Still no hope. Twrp won't regconized it. :crying:
If there no hope to solve this... I think ,I will sell my note5 for replacement parts , sadly.

I got into the same problem. I then ordered a replacement motherboard from China and installed it. After that it is working flawlessly.
I'm in same predicament pc won't recognize phone and charging is extremely slow. Attempting to restore old twrp backup or flash older firmware. Crossing fingers

Same problem but with 2 phones
My note 5 and my friends S6 edge were totally fine, but on our farm (which now i found that has a low voltage eccentricity at around 190 V), we put them on my charger (the original charger that came with the note 5) and both of our phones now have the same problem, they charge very slowly ( up to 6 hrs for a full charge) and are not detected by any pc using 3 cables that work with other phones normally, the charger itself is okay, and works well with other devices (at home of course, and fast charge works with other devices).
I have tried everything, restart, safe mode, delete cache, charge while its off.. with a number of chargers and cables, it does not make any difference.
If any one knows how to fix this, your help is appreciated.
Mine is a little different, My Note5 is not charging at all via USB but works fine with wireless charging. In short, even if i plugged it via PC or via charger, it does not charge anymore.
But I noticed something, when I am in TWRP recovery, my USB OTG drive is readable and when i am in download mode, Odin reconizes the Note5's COM port. I did a reflash of the stock ROM hoping this will do the trick. but it failed. still does not charge at all via USB.
Can anyone help me with this? Thanks in advance. all answers appreciated.
this seems like you have faulty usb port .

Massive Storage not working in T813, computer does not detect

Hello fellas,
I have a problem with my brand new T813 running the latest official firmware available (Android 7).
Massive storage is not working, my computer running Windows 10 with updated samsung drivers has failed to detect it. The device charges, but I am unable to modify the usb options, regardless the choice MTP always remain.
I have tried with three different cables, all of them work fine with my S7, the computer never detects the device, eventhough it's charging. This means it is not a problem with the device's micro usb port. I have the latest drivers, and I have also tried with all usb ports. None of them seemed to do the trick.
The computer has faulty usb 3 drivers, ever since I have installed Windows 10, the speed is not what used to be with the previous configuration. I have the same drivers, I don't understand what's wrong.
Any help would be appreciated, I have tried most solutions mentioned on this community and they didn't work. I can't flash the device because it is never detected. The problem still persists after a restablishment via the menu.
Download mode shows
QUALCOMM SECURE BOOT: ENABLE (CSB)
FRP LOCK IS OFF
[UPDATE] 06/08 11 AM
Left the device at SAMSUNG ARGENTINA repair shop. Also had to pay 300 pesos (around 20 dollars) as a diagnostic fee, they told me that if I accept the repair cost later on, they would discount the 300 pesos I have paid out of the total price. And if I don't, they will keep the money.
Will update again when Samsung calls me in a couple of days. Maybe this monday, I hope so.
[UPDATE] 06/08 15 PM
I have just received an email from BGH, which is the SAMSUNG ARGENTINA official partner for repairs. They told me that the problem is a FAILURE on the SUB board.
http://www.ebay.com/itm/Micro-USB-C...g-Galaxy-Tab-S2-9-7-034-SM-T813-/322414846816
The good thing, is not that expensive. The bad thing, this tablet hasn't arrived officially to Argentina, and since it has been bough in Chile, the guys at SAMSUNG ARGENTINA had to request an international order replacement, which I have been told it could take some time. But they will eventually get the piece.
Will update again.

Thanks for replying, please refer to first screenshot. No Mass Storage option appears after connecting device. MTP option seems to be forced, i am unable to change it.
The tablet is brand new, but the guy who sold it to me said that it has always been working. He even told me that it has been barely used, and that the device is recognized when connected to an usb audio system. It has been upgraded to 7.0.1 a couple of days ago, maybe that's the problem.
I have just tried with a macbook air and it didn't detect it either, it is only charging. The same computer has detected my S7.

A lot of people seem to have experienced this problem, the remaining solutions I didn't try are using other pc or try cleaning the female port with isopropilic alcohol. Hope it does the trick, otherwise I'm screwed.

When the problem appears with different USB cables and in different computers, as in your case, you have to look into the possibility that it may be a hardware issue.
I hope I'm wrong about this, but it sounds like the DATA+ or DATA- pin is damaged in your micro usb socket (pins 2 and 3, see http://pinouts.ru/PortableDevices/micro_usb_pinout.shtml)

Yes, I'm afraid it could be a hardware problem. But that would also mean the guy who sold it to me is lying. I have to say it, the device looks like it has been treated with care. However, i have noticed the plastic has worn out a little near the usb port, those black marks could indicate not so much care when plugging or unplugging the cable.
I hope we are both wrong about this. Tomorrow i will know. Fixing this is a pain in the ass, right?

¡Che! Replacing the microusb receptacle would not only be a pain the ass, but if you make a tiny mistake while soldering or desoldering you can end up with a bricked tablet.
Anyway, let me know what you find out tomorrow, good luck boludo.

Actually not too bad as the Micro USB port is a module and can simply be swapped out.

Problem with OTG&USB N950F

Hi everyone
here I've got a terrible issue with my note 8 and SAMSUNG USB OTG.
When I connect my otg and a flash memory to phone, nothing happens, unless you force restart the phone while the otg is connected. After booting I can access to my flash memory but after removing the otg and reconnecting it, again nothing happens unless force restarting.
I've tried everything possible. Downgrading, upgrading, 4 files rom, pit file, rom from different zones, but still have the problem. I have no other issues regarding the USB port and charging, fast charging, connection to computer and any other stuff works fun but this OTG.
I wanted to know if anyone have any solutions for my problem or if anyone had the same issue or not.
it is also worth to mention that I have not rooted my phone due to warranty issues, and for that I haven't tested any kernels.
thanks for everyone

That isn't right... As soon as I plug in my OTG USB key it detects it, no restart required.

Nope, I have developer options enabled but debugging isn't on. never had to enable file transfer.
When I plug in the OTG device I see a usb icon in the notification panel. Swipe down and pick explore. Mind you it only opens in the stock file explorer, I did have another file explorer that picked it up too but can't think what it is and it has been lost myriad of other apps I test and play with...
Just be aware that it may take a few seconds to scan the device,depending on size, and then display the icon.

i know it sounds weird but from past experience flaky USB drives are more trouble than they are worth, from first hand experience i know patriot, corsair and sandisk work well as OTG drive
also you neglected to mention the file system the USB was formatted with, i believe only FAT, FAT32 and exFAT are supported

also possible that the phone doesn't like your OTG adapter. I bought a usb 2.0 to type C adapter which doesn't even work on the phone - when I plug it in usually the moisture sensor error comes up saying water is in the device and I should let it dry. Unplug the OTG and the error goes away.
So... I bought a USB 3.0 A to type C OTG adapter and that one works fine with everything I've tested (usb flash drives, keyboard, usb ethernet adapter, etc)
I believe the USB-C to USB-A adapter that came with the phone is actually an OTG adapter (tested xbox360 controller and keyboard)
I also believe that the note8 can host usb flash drive native (no need for OTG cable) as i have a dual head USB-C and USB-A flash drive which is recognized once the USB-C end is plugged in

I'm test with any OTG cable or.....not work
also reconnect and again connected but no answer
only with force restart
Sorry to dredge up a semi old thread, but has anyone found a fix for this?
I'm having almost the same issue, I finally decided to try out the OTG adapter from the box and nothing works, it isn't even recognized. Tried ps4 controller, mouse, keyboard 2 different thumb drives. Can't figure out what the deals is.
Other than that pc connection seems to work and charging works fine. TIA
I'm having a similar problem. A month ago, used both OTG adapters (original from Samsung and a generic one) it detects my memory sticks as a hard-disk and was able to manage my files. But since a couple of weeks ago it does not detect them anymore. Is like it did not supply charger to them anymore. I have tried the USB debugging menu and no difference at all. Even I got back to factory reset expecting to solve the issues but nothing happened. The port as such is working perfectly because I'm able to charge through it. On the other hand, Samsung DEX is not working as well. It just charges the phone but never boot-up.
I'm just waiting for Oreo and hopes this will sort the problems out.

That sounds like a bodged port to me man
Is there any dust or dirt in there that you can see?
I really don't think Oreo's gonna fix that for you

Seems to be a little bit dusty. Anyway, the other thing is that, when the Usb is detected it ask to choose between transfer files, images, midi device and so on, even if I choose "transfer files" mode it always get stuck as "charge connected device".
Hi i have the same problem... my note 8 can connected mith my notebook, but my otg with an usb stick cant recognize my note8. I test the same otg with usb stick on my friends phone example S8 and it detects promptly all.
I hope the fixing take not long time. I waiting for help. Greets
Well, adding one more case here, my native file manager doesn't recognize any memory connected via the original otg conector, but, using x-plore file manager, problem solved, as I use x-plore since my symbian days, I never gave this issue much importance, this problem was present also with my note 7

This. I have exactly the same experience. I bought a couple of months ago a new Note 8, and finally decided to try the OTG adapter that came in the box. Nothing worked. I tried the adapter with a friends phone and it worked like magic (USB drives, mice, keyboards, controllers, etc.).
Would really apreaciate if anyone can provide help on this issue... Cheers!

Question My S21U does not connect to PC

When I insert my USB cable into the PC, there is no response, no notification sound saying that a device was connected. The phone simply charges and does not seem to enter file-sharing mode. There is no activity on PC or phone when it gets connected. Not even a USB sign, just "cable charging". Any ideas?
I am certain it's not the cable because when I connect my old S8+, it all works fine but my PC just doesn't react to S21. I've also checked the developer options and it's set to "transferring files" mode there.
I installed USB drivers but it didn't help. The only way my phone gets detected is if I enter download mode but that''s not very useful to me
Sounds like a driver issue.
Check Event Viewer for error messages.
Try looking under drives and opening directly from there.
Try turning off Developer options.
There are no errors in the event viewer, the computer simply does not react when I connect my phone. All it does is charging. Turned off dev mode too, no dice.
same thing here..
factory reset my phone
reinstall adb driver on pc
still missing usb options upon plugging in the cable
I'm thinking of returning the phone at this point... I've even flashed through Odin just now and it worked perfectly but it won't connect to PC.

I had the same problem, until I used the cable that came with the pods pro.
Its very weird because I have other high quality usb cables but they didnt work with my S21U exynos edition.
Only the samsung one worked.

I don't have pods pro though... The only cable I have is some generic USB cable that works perfectly for my S8+ and a USB-C to USB-C cable that came in the box with the phone. None of them work. I don't know what to do
Nevermind... I have just cleaned USB-C port on my PC and it worked! Still weird how it won't accept my high quality USB cable though
My S21U connects fine to my work PC but doesn't connect to my home laptop, both run Windows 10. The laptop doesn't react at all to the phone being connected, the work PC behaves as normal. The only difference is my work PC is on W10 Pro, the laptop is on Home, both are up to date. I've been blaming Windows so far but I have no idea if it's that or the phone.

Are you using the same cable on both your home and work PC? If yes, try different USB slots and make sure to clean them too, that's what helped me.

Same cable but I will check the ports on the laptop later, it is a good possibility that they are full of fluff.

Yes exactly and i tried the cable with 2 different phones and they work perfectly. When connected to S21U it only charges....
You need to use a full pin usb c cable. A usb 2.0 type c cable will not work
Connected fine to windows 10 pc here used my Xbox elite cable no problem. Hopefully you find a solution.

Same problem!
And cable is not USB 2.0. Cable from P40- Pro. I tried different cables, different PC, no effect. Model SM-G998B/DS. I contacted support 3 times, no effect. The "data exchange" option does not appear on the phone".
in the file explorer are you able to see more than just media files from your phone? are you able to see documents files, ex.. docx, pdfs? how about zip files and .exe files? are you able to bring any files from your pc to your phone? i'm not able to do those. any feedback would be appreciated. thanks!
Lol, Same here, expensive Cabels with quick Charge 3 etc. did not work, the cheapest cable i found worked ...

Thanks for the reply, I decided to just do the factory reset on my phone and that helped the issue. As well as Windows 10 updating the Samsung USB drivers to the latest 2.17 version.
