USB Data Not Working - Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe

Hello,
I have a Xiaomi Mi 9T Pro phone on which USB data transfer stopped working. Neither connecting the phone to the computer, nor connecting a USB OTG device work (although fast charging works fine). I'm not sure when it happened, however I think I updated the firmware/vendor sometime around then. Also, I'm running the latest Arrow OS 11 (which is quite out of date now..) I tried changing the board with the USB port but to no avail. I've also tried multiple USB cables, which I confirmed to work on another device. I even tried booting the phone into EDL (as well as fastboot) mode, however device manager doesn't recognize the device (and I doubt it's the drivers as it would probably result in the device appearing as QHSUSB_BULK, not "device descriptor request failed").
Has anyone dealt with such a problem before? Could it be caused by bad vendor/firmware? Or is it a hardware issue, which could be diagnosed? Perhaps the custom ROM could be somehow safely updated without a USB connection (with it being necessary to format data)? Thanks for any help!

Did you ever find the solution for your issue? I have a very similar problem, which appeared as far as I can remember without having done any updates before:
On my Mi 9T Pro I can slow charge (very slow, complete recharge takes 8+ hours), but I do not get working quick charge or a working usb connection.
I had the same problem a while back which was solved by changing the USB board. This time however, I have changed the USB board multiple times (at first I thought the new board was faulty) but I did not help.

Hello, I have similar problem. USB OTG doesn't work at all (in custom recovery or in rom). I guess changing USB charging port may help... but I'm not sure. Did you manage this problem? (I have other two 9t pro which works so it's not problem with USB cable).

[Q] Can not connect to my PC

It has just stop working when a plug in my usb to my pc i do not get "Turn on USB storage" on my phone. No usb icon also. The computer does not recognize the phone.
I have try different cables, computers and OS. Also did a factory resat and putt on debuging mode on and off. Also multiple restarts with no luck. I use stock rom.
Are my phone broken?
It's probably the usb ports though you have tried with other computers ;/
or the micro-usb port of your device

I had the same problem and I believe it is a phone issue. I tried reinstalling drivers, different USB ports on different machines, factory resets, different cables etc. At times when plugged in the phone would suddenly wake up and acknowledge the USB connection while at others it just started charging when plugged in to USB.
What confirms that this is a phone problem rather than a PC problem is that when I connect it to my office workstation that runs on Sun Solaris, it behaves pretty much the same, acknowledging the connection randomly. My HTC Magic on the other hand always connected to both home PCs and office workstation without any issues every time.
Finally I have returned my handset and asked for a replacement.

Good luck. It's a pity though as otherwise my handset worked perfectly with no reboots lags etc. I hope the replacement comes in soon and is bug free too.
I have the same issue with my macbook. Since yesterday my o2x isn't recognized by my mac.
I know it is not the usb cable, or the (micro)usb port, because when i plug the phone in at night my alarm clock on the o2x fires up (as it should).
So a connection is made, it just doesn't show "turn on usb storage" on my o2x. And i cannot understand why.
I am on the 0606 baseband, with the new FR19 ROM from Paul O'brien's Modaco (which is excellent btw).
If anyone has a solution, please let me kno
I have the same problem with my phone under modaco fr19, baseband + ril 606.
My pc is under windows vista and the drivers are installed correctly.
Awala
Update:
I received a replacement handset which was V10D 20110405 out of the box. No issues with USB connection.
Just out of interest, did any of you leave the phone connected to USB for a long time before it started failing? I used to leave it charging via USB all day at work so just wondering if there is a connection...
Update:
I earlier stated that my O2X wouldn't connect to my macbook. Yesterday I connected the O2X while on the Windows Vista partition of my mac, and it connected without any problem. After that, rebooted to Mac OSX partition, and no problem there. So I am a bit puzzeled about why, but it seems to work again.
In reaction to mparack's question, i sometimes let it load overnight via usb cable. But not a lot. I do not think that was the cause. I thought it was caused by flashing the 0606 baseband, but now I do not think that was the culprit.
Got back my phone from Telia on Wednesday. Everything worked fine. And I upgraded the phone using the LG update (Basbandversion: 1035.21_20110622) LGE version LGP990-V10c). After that the same problem! It feels like it's a bug in the software. Then they have changed the mainborad and it sounds unlikely that the new one is defective to.Goning back to Telia on Monday if they know about a bug or if you can get a new phone.
Those of you who have had the same problem what version do you have? Can I downgrade phone in anyway?

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 .

Mi5 Not Connecting To PC

I've been using my Mi5 for 6 months without any real issues, the occasional bug like fingerprint scan missing ect but overall no problem. Right now I am experiencing a problem that is driving me crazy. The USB options do not show up, only that it is charging. My PC doesn't recognize it anymore, and gives error 43. (USB device descriptor failed.) MiFlash, MiPCSuite all do not recognize it either.
Any help or solution would be greatly appreciated, I've spent days combing through potential fixes to no avail.
What I have tried:
-Mi PC Suite
-Mi Flash
-Default Android Drivers
-3 Different cables (2 xiaomi, 1 off brand)
-Factory Reset / Data Wipe
-QShortcut to force mtp usb options
-Developer options USB debugging on + selecting charging / mtp
-Reinstalling INF
-Disabing drivier signature enforcement
I've went as far as trying a different rom ect to no avail. It seems to revolve around the mi5 not recognizing usb connection, only charging for instance can't use usb charging
I've tried many options in terms of drivers, replaced the usb port and tech told me it was most likely motherboard issue and then tried to sell me a new phone. Unfortunately, I am living somewhere without many options for authorized support so looks like I'm out of luck.
Also tried different pc's, cables, roms, ect. All seems to stem from mi5 no recognizing usb
Hi,
Sorry not a solution but I'm having exactly the same problem too. Was fine for the first few months but then suddenly nothing. I've also tried it (with different cables) on :
Windows 10 PC
Windows 7 laptop
Linux Mint laptop
Macbook Air
And nothing but charging mode. Changing setting in developer options does nothing either. I've resigned to the fact it's most likely a hardware problem
Hi,
i had the problem that mi5 was not found by pc after a fresh install of windows 10 64bit.
I found a solution somewhere in the www
I have downloaded and installed the windows 10 N pack ( media feature pack ).
After that, restart the pc and try to connect the mi5 again.
This solution worked for me.
I have the same issue. Is there any solution? Is it covered by the guarantee?
Same problem here with mi6, maybe if we replacement de usb port of the phone?

Same Problem, Need Help
does anyone have same problem i need help and probably a fix to this problem, fastboot not detected too, i am currently using windows 10.. driver that i found online does not help either
hi, i need help in this case aswell. initially there no OS on my mi5, computers absolutely doesnt see phone (no unknown device etc, just nothing), so i can not send any zip file to install an OS. i can access trwp, tried OTG connection but it doesnt see either
Wow.. so I'm not the only one who has this issue.
Too bad there aren't any solution in this thread. My guest that it has something to do with the hardware. My phone is not recognized on PC and it is not charging properly either.
The strange thing is that it can charge on unknown chargers. It doesn't charge on "authentic" chargers (Xiaomi chargers, well-known brands like Aukey).
Solution
Guys (and gals)
I have the solution, i was as desperate as you all and it took a lot of digging into it, IT IS SO SIMPLE :
Download the app "USB SETTING" for MIUI and just turn on the option for file transfer, it also solves the ethernet problem. It worked for me, that's it.
(I also activated the USB debugging in the developer settings but I don't think it helped, as a matter of fact the right setting is present there in "select USB configuration" but refuses to work on my phone at least)
I hope it helped,
All the best on your paths <3

PC does not recognise phone [device descriptor request failed]

So the story is that i got a samsung galaxy note 5 (n920i) with a broken screen from my sister and it worked fine before. A year later i fixed the phone and wiped the files, cache and stuff i noticed that it did not charge with my aftermarket charging cable (battery was at 0%). I thought the cable was screwed so i used an official samsung one and it started charging. once it started up i did all the startup installation process and such but then i noticed that it would not use fast charge (i have an official samsung fast charge socket) even with the fast charge setting on. so i thought to plug it into my pc but it does not recognise it at all. (device descriptor request failed every time) I used many different ports on my pc and laptop, used many aftermarket and official charging cables, i even used it on devices like the gear vr and a docking station and they dont recognise it either.
I found a post saying to push up the tongue in the charging port which did not fix it, i tried all such drivers and fixes thinking its my pc and/or laptop but no luck, like i said i even used devices like docking station and gear vr and both dont recognise it either. So i just thought it may be the charging port its self and purchased a new one to install(i also got a new battery just incase) . After replacing both the charging dock and the battery successfully it still does not work on my pc nor does it charge properly. it is running on the newest update out right now.
edit: I also lost the little white signal cable for the antenna while replacing charge port but i have purchased a new one and its on the way. (if that causes an issue)
I have tried using samsung kies and smart switch with drivers and it does not recognise it either
I dont know what else to do can someone help me figure it out whats wrong.
Thanks
I have the same problem.
Is there any way to root note 5 n920v without pc?
My phone have a problem that does not connect to pc with usb cable, my last hope is to try to install a new firmware.
By research, i think its a software problem.

Question Mi 11 not connecting to my PC?

Hello does anyone else have a problem with the Mi 11 connecting with a USB? I have the Asus Prime Pro X570 motherboard with mutiple USB ports, 2 usb ports on the front of my Corsair 5000X and every port apart from 2 will only charge the phone. The two usb ports connected to the ethernet rail the phone constantly connects and disconnects and the select file transfer, no action etc on my phone literally flashes and has seizure.
It can't be the cable because it works on other PCs. Also tethering works through USB. It's only when I'm trying to access the phones files?
Hello I Have the same Mainboard with the same problem and what can I say... For me the solution was an other pc to unlock the bootloader and flash a cfw. Then tested on my main pc and still nothing. Then tested my three other USB cables and with two it worked.
I have no idea why that is a thing. Maybe the Mainboard USB problem that had to be patched since 1.2.0.0?

Maybe it's an Asus problem but I brainstormed and was like wtf it's android. If you need to transfer files you can use an ftp client and do it over WiFi, but it still sucks cause I can't flash anything
I had the same problem but after I connected the phone to a 3.0 USB port the problem solved instantly.
