Have you installed the Samsung drivers?

yeah i've tried installing the drivers. the phone isn't even putting the usb icon in the notification tray anymore. just starts charging and that's it. i go to usb settings/mass storage and nothing. any ideas?

I got that too, I just put the usb cable in another usb port on my computer and tadaaaa: problem fixed

I had this issue and read in a forum (not sure where wish I did to give credit) where u need to format your internal SD memory (the built in 16 gig SD) I did that and it started to work again.

How about Menu > settings > applications > usb settings > ask on connection.....

I had/have this problem sometimes too. choosing "ask on connection" usually works. I find that if you select anything other than "mass storage" then exit out, then go back in and choose mass storage, it works again.
Usually only have to do it once after a factory reset or on a new phone

I find my connection to be hit or miss. The pc picks up the drivers fine but doesn't mount the phone as a drive. Kies is a pain to get going too. I read on here that you need .net framework 4 and also no file names over 16 characters, and without kies I think you need to be in debug mode on application settings. I still need to try the short file names and see if it improve it but I never really hook up to a pc anyway, my father has win 7 and I have kies on his computer. I have linux mint 9 on my own so I rarely get to fitz with it on a windows machine.

I'm having this problem, can't get usb debugging mode to turn off. It immediately turns on when I turn it off. It's as the just says, "yeah, you can uncheck it, but I'm gonna leave it on."

[Q] My N1 Would not Prompt to Mount SD Memory When I connect it to my PC

I needed to transfer some files from my N1 to my Pc, so I connected it to my PC using the cable. I was expecting the black mounting screen prompting me to mount the SD card, but nothing happened. I restarted my device twice, but the case is still the same. What could have been wrong? I have not installed any app within this time, not removed any. I have used it in just ordinary daily manner, messaging and calling and nothing else. My N1 runs on Froyo, OTA. No jailbreak.
Please help. Thank you

u need to assign a drive letter to your SD card

Noob answer: is it on the status pulldown bar?

Do you have USB Debugging enabled?

Does the phone recognise that it's been plugged in (ie start charging)?

Similar problem
I am having a similar problem with my N1 running CM6 stable. When I turn off USB debugging and plug the phone into my Win7 laptop, I get the USB connected screen, but when I turn on USB storage the SD drive doesn't mount i.e. I cannot see/access the drive in Windows 7. The N1 status bar says USB storage is on.
Under Device Manager, the N1 shows up as Android Phone-->Android ADB Interface with driver version 2.0.10.2 dated 11/08/2009.
Any help would be much appreciated.

No, THIS is exactly the problem, the phone dies not recognise that it has been connected to a computer. It does start charging, but no sign of SD memory mount/unmount. Nothing. Just simply charging.

No, USB debugging is not enabled. I double checked it.

I guess that Windows also doesn't recognize the phone as anything (Device Manager doesn't show anything new plugged in)?
In that case, enable USB Debugging, and see if the phone is recognized by Windows.
If it is - the problem is somewhere in SW.
If it isn't - then it might be a faulty USB cable or connector (from any side - phone or PC).

same thing happens to me from time to time. restart your computer and that should fix your problem.

[Q] Can't connect my Captivate through USB anymore

Hi everyone,
I'm having issues connecting my Samsung Captivate to my computer. For about a week, it worked fine, I was able to transfer files to my phone but recently I noticed that the "USB connected" notification is not showing on the phone when plugged in to the computer.
Now, when I plug in my phone to the computer it just charges but doesn't comunicate with my computer. A friend of mine bought the same phone right after I did and he gets the "USB connected" connected when he plugs in his.
I tried using his USB cable but again, the phone is not recognized by Windows nor the phone detects it is connected to the computer. I've tried installing several USB drivers that I've come across on several forums, but nothing. I even downloaded and updated Kies to the latest version, but still nothing.
My phone is unlocked and NOT rooted, and I'm using Windows 7 x64. I've set the USB Settings to Mass Storage, even to Ask on Connection, but it doesn't ask anything when I connect the phone to a USB on my computer.
Sometimes Windows knows there is a device connected but says it couldn't recognize it.
I already did a factory reset, but the issue was not solved. I've tried connecting it to other computers, but still hasn't been able to connect my phone correctly.
What could it be?
Thanks!

Hmm. You have Mass Storage selected and up-to-date USB drivers. Try selecting USB-Debugging and Stay Awake in the Development option of your phone. If that doesn't fix it, then I have a few other ideas.

Make sure the usb door is completely open, it should click into place, some users have reported this solves their usb issues.

I did what you told me, but still my phone ain't recognized by Windows nor my phone is aware that it has been conected to a computer
What other ideas do you have in mind?

I'm sure usb door is completely opened

Have you tried using a different USB outlet on your computer? I had this same issue when I plugged my phone up using the USB outlet on the front of my computer then when I tried the one on the back of my computer it worked just fine.

Are you running a launcher app? I use launcher pro and can't connect until I change back to the default launcher with home switcher and launch it.

First off, think back. If it worked for a week and then suddenly stopped, what changed? Maybe you updated something on Windows or changed something on your phone. There's a reason it just stopped.
You can try using a free program called USBDeview.
It might do the trick for you and help you install the correct drivers. I'm thinking you no longer have them.
1. Download USBDeview (link is above)
2. Plug your phone in and open the program. Find all the HTC drivers-delete them
3. Unplug your phone and plug it back in
4. The correct drivers should install automatically
You can also try updating the drivers manually.
Galaxy S drivers (These are for ADB, but will work fine)
1. Click the Start Menu on your computer and right click "Computer"
2. Choose "Manage" --> it will ask you to continue --> "Device Manager"
3. Plug you phone in and look for it to pop up, probably under Portable Devices
4. Right click --> "Properties" --> "Update Driver" --> "Browse" --> "Let Me Pick" --> and navigate to the location you extracted the drivers to.
This is most likely a driver issue. I doubt your phone is messed up. You'll get it eventually. I also had a hard time getting my Captivate to connect. After uninstalling and reinstalling my drivers (more than once) it finally worked. One last thing, for now. When you uninstall drivers, also make sure you don't have any installed under your program list. As in, Control Panel --> Uninstall a program. Good luck!

A friend of mine, who bought the same phone on the same day as I did, plugged in his phone on my computer using my cable to the same port my phone was connected, and he did get the "USB Connected" notification on his phone

I just did the new AT&T update and mine is now having this problem. I have to manually go into manage applications > usb settings > mass storage to get it to work now

I did all that yesterday, but the device ain't listed in the USBDeview nor it shows up in the Device Manager

did you finally fix this problem? because I'm having the same issue here

Same here. It was working fine, I could connect to Kies, transfer music in Media mode and see both sd drives in Mass Storage mode. Then I rooted today and now I get nothing. In anything but Kies mode I get the Windows Bong of Recognition, but still not visible in Explorer. Also, my Home screen stays active instead of switching to the USB animation like it did before. I know this can't be a consequence of rooting the phone, can it?
EDIT: More weirdness, with the phone connected in Mass Storage mode if I look at My Computer in Explorer there are 2 extra drives showing, but they are greyed out and when I click on either of them it asks me to insert a card as the drive is empty. WTF???

UPDATE: I unrooted and managed to get my USB connection back to working. It is still a bit flaky as I sometimes have to disconnect/reconnect several times before it works, but at least it now works although it sometimes loses sync in the middle of transferring a file. Can't imagine why simply rooting the phone would cause the loss of USB connectivity. I am going to reroot and see if it occurs again.

OK, a rerooted the phone and this problem is now back. I have no problem connecting while in debugging mode. I installed OCD (non-Market apps mod) and when I turn off debugging and connect I get the Windows bong and see the USB icon in the Notification bar, but the MTP screen never comes up and I can't see the phone in Explorer (Mass Storage mode) or in WMP (Media mode). Kies can;t see it in that mode, either. I really don't want to have to unroot every time I want to look at the phone contents. Any ideas? PLEASE!

I'm having a similar problem - I installed the Perception ROM and immediately afterwards I can't see the USB connection at all from my PC or my Mac. The USB icon on the phone does not come up either.
I'm trying to get my hands on a different cable - but the weird thing is when I plug the USB into my computer the phone starts charging for like half a second and then stops.
This is really annoying. I tried changing the rom to Cognition 3.02 but that didn't change anything.

There are a few topics on this here on the forum - I would recommend the following:
How are you rooting your phones? Nobody has said exactly how they are doing this. Are you using recommended rooting methods? Or are you using some app found on the market?
Make sure you have USB De-Bugging is turned on.
Make sure you have it listed as ask on connection.
For those who can see the drives in Windows...
Plug in your phone and then pull down your notification bar and click on the USB connected message. It will give you an option there to mount your SDCard(s) to Windows allowing you to transfer files.
Kies is junk - I'd recommend uninstalling it as it seems to cause more issues then it solves.
Use the drivers I have posted in the Q&A section (these are the ones that are linked in Design Gears Odin 1 Click Back to Stock post btw) - but I would try and COMPLETELY removing the pre-existing drivers before installing the new ones.
Make sure the USB Cable is plugged into the back USB port that is directly on your motherboard - this will ensure it's not a computer/hardware related issue.
I know of one user who had to go through his computer and manually remove all remnants of other drivers. I have my phone connected to both a Windows XP 32bit and a Windows 764bit systems and have been lucky to not have any USB issues.
If none of that works - I'd suggest taking it to your nearest AT&T/Rodgers shop and see if they can get the phone to connect (make sure it's back to stock!). If not they should warranty replace the device.

This isn't my first rodeo... But to answer your questions:
I used the rooting method posted in XDA forums - the one-click rooting.
I've used the drivers included in the xda-forum. Not the kies software.
The only thing that changed was the loading of a new custom rom. The cable works (confirmed on my friend's phone). I can't get odin to restore back to stock because I can't get the computer to recognize the phone in either normal or in download mode. I've restored to stock using the jh7 in the stickied q&a thread
I don't think it's a hardware issue either - I think it's software-based. I'm going to try to take it to an at&t store today at lunch to see what they say.

I also have that problem only I noticed it when I cleared the dalvik cache. It messed up the auto rotate so it was always sideways and now I have no connectivity to the PC. Let me know how ATT treats you.

[Solved] USB Mass Storage Mode Issues (CM7)

I am having issues with the activation of USB Mass Storage mode on CM7 v7.10. When I first connected my nook (just got it yesterday), I was able to enable mass storage mode as per normal. However, after this it's just stopped working!
There's nothing wrong with the cable afaics because the empty drives come up on the PC (Win7) no problem, it's just that the nook doesn't detect that the USB is plugged in and so never gives me the option to enable Mass Storage mode. I have had success once running ROM Manager's 'Fix Permissions' function, but since then it's not made any differences. The issue remains on multiple PCs with multiple cables.
Anyone got any fixes for this issue?

+ can you wiggle the micro-usb end a bit to see if anything better?
+ do you have the "usb debugging" check?
+ do you see the usb icon displayed on the NC notification bar?

- No wiggling makes any difference
- Tried with USB debugging on and off - no difference
- No USB icon (but empty drives still show up on my PC) so there is some kind of connection going on.

If the empty drives do show up on the PC, it definitely some sorts of connection made, it's a good sign.
Now back on your NC, go into Storage, try to Unmount then Remount the uSD and see if it gets any going.
Note: leave the Debugging USB Mode on.

Might also be worth considering moving from 7.1 to the MiRaGe 7.2 build. I'm not saying there is a specific fix but using the later ROM may help and I think most people find it more stable, faster and problem free.

Yeah, I actually updated to KANG 7.2 this avo and the USB Mass Storage option is back!
Thanks everyone for your suggestions!

I currently having KANG Mirage 7.2 with Tablet Tweak but it did not work. I bought an OTG cable from ebay so I assumed it's bc the OTG cable. The Drive works fine on my laptop but nothing appears on the Nook.

Maybe a re-flash with the same ROM might do the trick?

I'll try to reflash sometime soon!

uSB mass storage
I had the same issue. Have the USB connected and while connected reboot your device once it has rebooted you'll be able to access the USB files on your device. You'll be able to see the USB signal at the bottom, which you can activate. You'll have to do this most likely everytime you want to access USB storage

I'm on MIRAGE 7.2 running off EMMC. SD card is in the Nook.
I shut nook off, plugged in the cable to my pc and started the nook.
5 drives show up but I cannot access any of them. The USB icon is in the tray on the Nook and it says "USB connected". Just above that it says, "USB debugging connected"
Anybody have any success?
After doing some reading I've decided to use ES-FILE Explorer wirelessly. Its very easy to use. You need to SHARE folders on your PC in order for it to access the files.

Playing around with the USB option some more, I didn't realize that you could TOUCH the message in the notification bar. When you do, it launches a program and from there, you turn the USB connection on or off.
Geeeeeeez........ya learn something new every day.

Help needed with file transfer

Hello everyone,
I am trying to transfer files from my computer (Windows 10) to my phone (Android 5.0.2), but it only says "preparing to copy" and then freezes there. Sometimes canceling the copy is enough, but sometimes it freezes the explorer so I have to disconnect the USB plug.
I tried with PC companion (which redirects to windows explorer), Media Go, Total commander. No success.
I saw that many people had/have this problem but I couldn't find any helpful answer though... So if someone experienced this and managed to get through, please help. I'm really desperate.
Thanks

Try transferring over Bluetooth see if that works
Sent from my Xperia Z using XDA Free mobile app

Bluetooth works. But I am trying to transfer through USB cable since I don't have bluetooth on my computer.

well, thanks to windows 10 for that :] If you would read they ToU you would know that they probably make copy of this data and send them to microsoft servers, that why its dont work :]
But seriously. go to device manager and check if your xperia is visible as device(in usb controllers and other devices)
If you dont see anything, keep this device manager window active unplug phone, plug it again and see the difference on list.
Then select this device, uninstall it from your PC, unplug your phone, and plug it again.
After next time you plug it all drivers would install again and try to transfer files again.
If this dont help check your phone with scan tool that windows have in proprietaries.
Also, because of flaps in our xz, I very often use WiFi transfer, its almost the same speed.
Plug your device, open Settings menu on phone , go to "Xperia connection" at the end you have "connection via USB"
There you have "associate with PC" click it and then go to your PC, My computer select phone(right click) and from list choose "configure network" wait for configuration(sometimes its stop responding, just leave it for few minutes).
After that you can connect to your phone just by clicking that "connect to Computer" in xperia settings.
You have access just like via USB to phone and SD card, speed is almost the same.

Hey Akinaro,
Thanks for your detailed response.
My device is visible as a device, I can access SD card and internal memory, well no problem there, I already uninstalled/reinstalled the drivers.
I also tried other USB ports but no success. Tried to use the cable with other phones, it works fine. Tried another computer, same problem.
When I try to plug the phone to rear usb port, copy works for like, one or files, then freezes. It then says that the device has been disconnected. Seems like the usb connection kinda drops...
I will try to associate with PC and let you know.
