[Q] USB Storage doesn't show up in windows 7

I have not had this problem until recently and not sure what has caused it. My phone is not showing up when I mount my SD card. Also undetected by ADB. I have tried multiple cables, different computers, and also reformatted my computer and installed fresh drivers just in case. My phone does however show up in Odin and I can flash a modem no problem. I was thinking about wiping my phone back to stock and going from there, but I am afraid that will not fix it and I will be stuck at stock. =(
Thanks,
Jaculop

Had the same problem. Had to reload the drivers even though my other Epic was recognized just fine.

Same here, its' like it woked one day and didn't the next. I had 2 problems, one was the fact that only half of the usb jacks on the front of my desktop work (dumbass), and I had to re-install the drivers found on Samsung.com. My computer also will not recognize the sd card until you turn on mass storage from the drop down menu on the phone after the usb is connected.

What I did was turn on USB debugging, connected the phone in the drop down menu, then went int control panel>device manager> and looked for either "Other" or something in the USB connections. I found Samsung Android. I clicked that and hit update drivers from Windows Update. It took like 30 minutes to load all the necessary drivers then connected fine after that.

I have tried uninstalling/reinstalling drivers. I am pretty sure I have tried the update driver thing through device manager, with it saying I already had an update to do driver. I have also tried with/without debugging and also manually selecting use as a mass storage device. Just kinda weird it shows up in device manager, just ADB doesn't recognize it or as a mass storage device. I am starting to think it is something more with my phone as it doesn't show up on other computer and tried other cables. May just say screw it and try Odin.

You can uninstall the drivers, then let Windows Update find the drivers again. It needs 5 drivers altogether. My problem was similiar. It wouldn't recognize my phone with USB debugging on, yet had no problem recognizing my other Epic so was sure my phone was screwed up. After Odin it did recognize it but wouldn't after rooting and putting on a GB leak ROM but again the other phone was fine. Forced driver update and has worked fine ever since. Although one phone shows up as F and the other as E. Not worried as long as it works...lol.

I uninstalled the Galaxy S 64bit drivers but the uninstall option that came with the package. I plugged in my phone, it attempted to find drivers and said unsuccessful. I click, search automatically and it comes back with nothing.
Also it says it is Samsung CDMA Technologies.
Edit: I just tried manually updating the drivers by pointing to the driver location instead of using the provided installation. I see only 4 drivers installed. Samsung USB Composite Device, Samsung Mobile Modem Diagnostics, and one other I am unable to find the name of.

There is also a CDC driver.

I fixed the problem. In case anyone else runs into it, it's simple to fix. I was afraid to ODIN back to stock in case something was wrong and unable to root/cwm again, but I grew some balls did it and it's now working flawlessly. Must have been something messed up with the system files on my epic, that even a wipe and reflash from CWM would not fix.

Did you root and reflash your ROM and try it?

Yea, I rerooted and flashed my rom. Everything is working fine so far, along with my SD card and phone showing up on my computer. Before it was just showing up as Samsung CDMA Tech. now it is showing actually showing the samsung model number. So something happened with the phone before. Not exactly sure.

Glad you got it working. You were lucky Odin still recognized it.

USB problem

I'm running cyanogenmod 7 on my evo 4g and when I plug it into a computer it only charges and never prompts me if I want to connect as a disk drive. It used to but now it just stopped. I had a backup of my rom so I put it on my girlfriends evo and hers still connected to the pc like normal but mine will not give me the option to hook up through USB. My computer says unknown device. Any help would be great. I can provide more info if you need.

More info. It gives me code 43 in windows 7. I was able to hook it up in xp but when I tried doing anything it no longer was able to detect the phone. I did a factory reset and it still doesn't work. I'm at a complete loss. I feel the only thing left to do is revert completely back to stock losing root and starting from scratch.

perhaps try completely uninstalling the device from windows in Device Manager. Then plug it in again and let it re-install the drivers

I've tried that on two different computers with windows 7. My gfs fone reads fine with the exact same rom but mine wont.

It seems like the drivers on the phone are corrupted or something. At one point I found a forum that suggested to turn off bluetooth and a few other things. I decided to see if turning off my wifi would do anything and finally my phone showed the usb debugging notification and the mount as usb notification but it wouldn't mount so I restarted my phone and now it's back to doing nothing but charge the phone.

The only difference between the two phones is the rom then? Perhaps make a backup and flash a different rom or re-flash your current rom to see if that helps

I actually took a backup of my rom and put it on my gfs phone and hers worked. we had the exact same rom. I will try installing a different rom however and i'll let you know what happens.

Okay so I had a back up of sinister rom so I restored it and now it asks me if I want to connect as a usb device and so I do and my computer still says usb device not recognized or whatever.

Wow so I tried a backup of sinister rom that I had and suddenly it asked if i wanted to connect as a disk drive but windows was still saying usb device not recognized. I reverted all the way back to stock losing root privileges and it still doesn't work. It appears to me that it is a hardware problem. I don't know what else to do.

ok, so I hooked my phone up to a computer with ubuntu on it and my phone showed up but then when I went to explore the sd card it said permission denied. Then I hooked it up in windows 7 and it showed unknown device under universal serial bus controllers(as usual) but it also had it under modem, which is what I want.

Okay, got it working on this computer. After plugging the phone in several times it still said device not recognized. I have also been pushing ##data# and it was saying the same thing. I decided to shut my phone off one last time and when I hooked it up i pushed ##diag# and now it works. ****ing stupid. Glad it's working now.
UPDATE: Now all of the drivers install when I plug the phone in except the HTC DIAG doesn't appear even when i enter diag mode on the phone. this is the only driver i need installed but i can't install it because the computer isn't picking up that part of the device....This is getting irritating.

Turns out my port is ****ed up. I'm gonna have to order a new one and replace it.

[Q] USB Connection problem

Hi All, I've got a USB connection problem with my Galaxy Nexus. When I connect it to a computer, it will start charging, but doesn't show that it's connected to a computer and the computer doesn't show that a device is connected. I've tried on a few different Windows machines and don't get any change in the device manager. There is no "unknown device" nor device with an error. I've been searching the Internet and this forum, but still can't find the problem after a couple of days. Here's some details and things I've done:
I did not install the "force fast charge" kernel mod.
I've tried a couple different cables and verified that the cables worked with my wife's Galaxy II.
I've tried several different computers.
I've tried MTP and PTP storage options.
I rebooted everything several times.
I drank heavily.
I tried a factory reset.
I updated Windows Media Player to get the latest MTP software.
I installed drivers packages even though it never gets to the point of installing drivers.
Does anyone have any other ideas before I smash this thing with a hammer?

Does anyone have any ideas? At this point, I'm thinking there is a hardware problem.

Go into Menu -> System Settings -> Developer Options -> Turn on USB Debugging.
Not a guarantee, but something to rule out.

I've got USB Debuging on. Thanks for the reply.

Can anyone help? I'm having the same exact problem. My phone charge but is not detected by my computer. I am having this problem right after flashing AOKP ROM B35. This is very important, one mistake and my phone will be bricked as a computer to phone is so important !! There is nothing detected at all under device manager. Tried it on several laptop to make sure it isn't just my computer.

someone?

Uninstall the drivers you have for the s2. Reboot and install the official drivers for the galaxy nexus. Reboot. Then try.
If that doesn't work... let the phone load a while and just keep trying other ports on the computer. I saw this with my other gnex that it would take a while to realize a USB to be connected. Also make sure the USB is in completely... don't jam it in but make sure you know its All the way in. ( no pun intended) What's funny is my gnex will detect it instantly... but the other one takes a few tries.

Thank you dude. It doesn't work. Prior to installing this rom, my nexus is detected instantly. There is something wrong with the process i root or something. Now i can't do anything as It is not detected by my computer. Someone please help.

Indeed is the rom that is causing the problem. I opened NEXUS toolkit and rebooted my phone into boot image. It will sense it and i can operate from there. I've restored to factory and now my phone is being detected. I hope the thread starter gained something out of it too

[Q] USB not connecting to computer

So I can't get my s3 to connect to a computer. I have tried three different computers, two windows and one mac.I have also tried three different usb cords including the one that came with the phone and a brand new one I bought just to see if it was the cord. Have done a factory reset and tried everything with usb debugging on and off. My phone will charge but the computer doesn't recognize it. I have reinstalled the drivers twice on both windows computers and tried the Kies troubleshooting. I have also put it into download mode and Odin doesn't recognize it. When I plug it into the computer nothing happens, no sounds or messages saying something was plugged in. The phone does not have the option in the notification menu for usb debugging. I can use AirDroid to put just about anything I want to on my phone over wifi so I am not too upset about it not connecting but I would really like to put CM10 on it so I kind of need it to connect. I am using the stock AT&T rom. I rooted the phone awhile ago but then wanted to update so I went back to the stock rom and then updated. It would still connect to the computer after this update. Unfortunately I did not reset the flash counter so I doubt AT&T will do anything about it when it shows I have messed with it. I kind of think it is a hardware issue on the phone after doing all of this. Does anyone have any other ideas on what I could try?

Windows won't recognize t989

Hello all!
First: I promise I searched the forums and google as hard as I could!
I'm running AOKP JB with CWM, although the problem was present on stock ICS from T-Mobile.
Symptoms: Computer and phone will refuse to acknowledge any connection (nothing shows up in Device Manager), except the phone will still charge. If I do the "remove the battery with USB plugged in" trick, the first time I do it, it will recognize an unknown device, but kies and adb won't recognize it. If I unplug it and plug it back in, it'll go back to not acknowledging any connection.
I previously programmed it (when I was still running stock ROM) via ADB via WiFi, but I need to be able to use ADB via USB. Besides, I can't seem to get ADB over WiFi anymore.
When I plug it into a different computer (Win7), it will, however, recognize my phone.
Earlier this year, before I ever tried programming via WiFi, it connected to my Win8 machine with no problem. I don't think it's a problem with the wifi setup though because the ROM was reinstalled and of course I've restarted ADB in USB mode in the months since...
What I've tried:
Reinstalling Kies
Reinstalling Samsung USB drivers
[^]Restarting the ADB server
Updating ADB
Trying different USB cables
Trying different USB ports
Toggling USB debugging
Toggling MTP mode
The UART thing from the dialer
Restarting the phone and the computer (of course)
Checking to see if my computer's USB drivers need to be updated
The android terminal command "setprop persist.sys.usb.config mass_storage,adb"
Pulling and replacing the battery while connected via USB
Crying in a corner
If anyone can help me, it'd be greatly appreciated! I'm all out of ideas and Google is no longer helpful =/

try to uninstall the drivers that are present anything samsung related to your drivers ... then connect the phone and let the process do its thing if you have the samsung drivers saved on your PC and the drivers still aint working update the drivers and then manually click where the drivers are to install them and hopefully it will work and when you tried MTP is it the only option it gives you no storage or anything ??... and is usb debugging on when you are trying all this ??

I tried on my work computer that didn't have any samsung drivers and when the "unknown device" dialog popped up it didn't do anything or install anything, nor did it show up in Device Manager. Unplugging and replugging it back in did not reproduce the dialog box. Togged USB Debugging and still no dialog box saying it recognized it.
The thing with the samsung drivers is that they're self installing so even if it popped up in Device Manager, I wouldn't be able to manually update the drivers =/
I tried MTP both with and without USB Debugging, although it also gives the option for PTP.
At this point do you think I should unroot and go back to stock? It's not been recognized on three computers now! =[

Are you using the stock cable? My computer wouldn't recognize mine without it.

Both the stock cable and a generic cable.

Similar problem
Similar problem as the OP. And hi guys, it's nice to be on these forums.
My device, when I plug it in using the stock cable, doesn't even charge. It doesn't show up in device manager, nor does it give me a notification, or say it's unsupported and bear that yellow icon. I have tried using different USB ports, I have tried the toggling USB debugging, I have tried restarting phone, computer, and taking out battery. I have tried that PDA/MODEM dialer trick. I am using 4.1.2 Jellybean, not rooted. (that WAS my goal,, until I hit this roadblock) I have not connected it to the computer in the past, it's relatively new. I'm thinking the cable is bust.
Any suggestions would be appreciated. It charges fine through a wall outlet plug, be it generic or stock.

so guys ive come to a conclusion i think its something in the samsung usb cables try getting yourself a blackberry usb cable , TRUST ME !!! ever since i got my phoness etc... tablet and yadi yadi samsung usb cables have always seemed to give me problems i think its because they are multi data/charging cables and when using the blackberry usb cable i have never ever once encountered a problem with any of my phones sd/storage problems do yourself a favor and pick up one of those cables and you will be golden !! if not then i guess im the only lucky one :LOL here you go http://www.amazon.com/Blackberry-Travel-Adapter-Micro-Cable/dp/B004VMVSYK/ref=pd_sim_cps_2 5 bucks!
Edit also one more test boot into recovery and click in the advanced menu and see if mount usb works for you in recovery mode ??

FIX (try using a generic cable)
I actually solved it on my own! After borrowing a generic cable from a friend it booted up! The Samsung cable was just not doing its thing.

yeah im telling you those cables they provide are JUNK!!! i only use my samsung to charge because they do that well but data they are str8 CRAP!! glad you got it up and going

OP
Hope OP will have the same luck as me...pray to the Android gods...
