[Q] PC Not Recognizing USB as Mass Storage

I'm currently on DK28 and anytime I plug my phone into my computer via USB cord it just shows that it's charging. This is an issue since I would like to switch to EB13 and I need to be able to use Odin for the EB13 modem. I've tried uninstalling and reinstalling the Samsung drivers several times and not just on this computer, on two others that I have. I've also tried multiple usb cords and it's all the same thing. I've Googled the problem and everything I've tried has been useless to me, including the PDANet thing. So my question is is there any other way for me to be able to update to an EB13 rom without having to connect via USB? Or does anyone have any other ideas as to how I can fix this? I've been just using a microSD card adapter to put things on my SD for awhile now so that's never been a problem but I can't use Odin unless my computer recognizes my phone I guess.
HELP!!

Have you gone into settings, applications, development and unchecked USB Debugging?
I also have read numerous times where people have found the USB connector on the phone had something bent and was preventing a full good connection.
Good luck

You have got to be missing something drivers can be 32 or 64 bit make sure you have the right one for your computer. Is usb debugging checked in settings/app/development. Randy Shear has alot of step by step stuff for on youtube that might help

Yeah I have USB debugging checked and my computer is 64 bit which is also what my drivers are.

Turn off anti virus and dl driver again thats what I had to do. Reboot both devices also

UN checked?? if it is checked, you can't use mass storage

Tried that too and apparently that wasn't the problem. :\

I read where one person who was having something like this was told to turn their computer off; plug in the phone to the usb and turn the computer on and it worked.
Maybe try that?

I've had this problem, got real annoying after a while. I ended up reinstalling the drivers and turning off usb debugging and it would go into mass storage. Re enabled and tried again, and it continues to work.

Thanks for trying to help guys but unfortunately neither of those things worked either.

I had this problem. I flashed a different ROM (try downloading a new ROM from the phone) then flash it after following the appropriate instructions.
The ROM I had that problem with was Nebula ROM, I fixed it by flashing Bonsai v2.0.

Well I have now tried that as well and even that didn't work. This is so ****ing annoying.

Try flashing another ROM instead of Bonsai. I hate that you're stuck, but I'd try a few more ROMs before giving it to a Sprint Store.

I had this problem as well and did everthing mentioned here as well to no avail.
Now here's what worked for me.
First, install drivers on another pc (ensure that you connect, wait for drivers to load, disconnect and reconnect your phone at least twice..sometimes a takes a couple of connects to install the drivers fully).
Next use odin to flash DK18 stock firmware. When you connect your phone..suddenly mass storage will be back again. You can then load whatever firmware you wish.
This has worked on my phone and a friend's with the same issue.

I had this happen to me on 2 different machines:
- First time: A restart fixed it
- Second time: My phone didn't like the usb ports on my work laptop's docking station. The cable would only work with the actual laptop's usb port.

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.

Help!! USB connection not recognized...

I connected my SG2 via USB cable to my PC and started seeing this error
"One of the USB devices attached to this computer has malfunctioned and Windows does not recognize it. For assistance in solving this problem, click this message."
I have tried everything from changing cables/PCs/enabling/disabling USB debugging to *#7284#, and none of them work ...
Is the device bricked, is there any hope of revival..please help i got this phone myself paying $400

Does your phone turn on and work and a connection to PC the only problem? If so your not bricked...you prolly need to install the drivers in order for your PC to recognize it so install kies on your PC
Sent from my SGH-T989 using XDA App

Yes phone turns on, charges through the port...just that it is not recognized by the PC....what could be wrong?

As I said previously you probably need to add the drivers on your PC install kies on your PC
Sent from my SGH-T989 using XDA App

Make sure you use one of your rear usb ports also. I had an issue with drivers installing in a front usb port.

Phew it turns out to be the samsung driver..I believe kies update must have corrupted and stopped the pc from recognizing the phone....

The definition of "bricked" is having a really expensive
... brick. It means your phone doesn't turn on no matter what you do to it (short of a JIG and that's not guaranteed) the "USB device not recognized thing" is a problem w many windows devices my vista computer does it all the time and I just switch ports.

Having same/similar issue
Hey, was there every a solution found for this?
I'm having basically the same problem...using the cable that came with my phone, and have installed Kies (fresh). I have tried toggling multiple settings. I tried uninstalling kies and reinstalling. I tried using pdanet for the driver. I have tried a few different roms, as well: Darkside 2.4, 2.5.1, and gingersnap 1.21. All have had the same result.
When I plug the phone in, it beeps (charging) but no notification for usb settings (disk drive, sync, etc). On my computer, it pops up "USB Device Not Recognized" and says the device has malfunctioned, etc, same as OP.
In Device Manager, it shows under USB as "Unknown Device".
I have tried this with two Windows 7 laptops, and a Windows Server 2008 R2 desktop. Also tried with a different cable. This cable was able to transfer data from an external hard drive today, so I doubt anything is wrong with it.
Any help is greatly appreciated!

Did you try the drivers separate first or Mtp mode
Sent from my revolutionized Samsung infuse

I tried without the drivers, and went to wireless and network > USB utilities. The only option in there, however, is "Connect storage to PC". If I try that, then plug it in, the phone acts like I hit the back/undo button. It doesn't show that anything is connected, nor does it give any other options. At this point on the computer, I get the "USB device not recognized" error.
This happened before installing Kies/Drivers, and still happens after installing drivers and kies.

try another usb cable
i had the exact same error, and it ended up being a good USB cable that went south

I will try a different cable when I get home - Have a month old cable for a mytouch 4g that I know works.

Okay, I tried it with the other cable, on a desktop in the rear port. same thing...Phone start to charge, and I get the error that the device malfunctioned, yada yada.
Any other ideas? Should I try to connect in Download mode?

Alrighty, so in the end, I ended up completely unroting, using terminal emulator to remove superuser.apk, busybox, and su and putting right back to read only. Then in CWM, flashed a stock 2.3.5 ROM (Zedomax). However, I now have the 2.3.5 ROM and the 2.3.6 KL1 Kernel...
I'm planning to return to Tmobile/Samsung - will the kernel and rom versions not matching be a huge red flag??
Any help is appreciated. I have tried to flash the 2.3.5 kernel, but I always get an error that it's not signed/verified.
Ideas?
I was hoping to grab the 2.3.6 OTA update, but it says there is no firmware update. Is there an update file I can put on the SD card and update using the stock recovery?
UPDATE:
I called T-Mobile Customer Service today, and went through the "troubleshooting" with them again. They ended up sending me a new one, overnight. They didn't ask anything about doing anything custom with it like rooting or other modifications.
I'm not sure if it made a difference, but I'm within 90 days, and also have the "best" insurance/warranty coverage through T-Mobile, and whoever their insurance provider is that I signed up for when I bought the phone.
Final charge is for $5, which I was told is some kind of fee from Samsung, but will appear on my bill.
Anyway, not too bad. Can't wait to get rid of touchwiz again when I get the new phone!

FYI, I just went through the same thing. Decided to finally root my phone after owning it for 2 weeks.
Phone nor the phone would recognize USB data, but would charge. Tried another cable and no luck.
Rebooted the phone. Works like a charm now.

[Q] USB Data Connection Issue

I used to be able to plug my phone into my PC and slide down the notifications to enable a USB connection but I'm unable to anymore.
I checked that debug is on. I've even tried via the Wifi Settings USB Connection method. The phone will charge but is not seen by the PC. I've tried other PCs and other cables. It doesn;t show up in Device manager and I've also tried the windows drivers for the phone.
The only thing that has changed in the past month or so is that I replaced my Clockwork Recovery module with the stock recovery module and my phone is no longer rooted. Any ideas anyone?

Just enable USB storage before plugging in

Like I said I tried the Mass Storage connection method via the menu in Wifi Settings. The onscreen instructions say to enable then to plug in. Still get nothing.

Try reinstalling the driver that might do the trick. I am having the same issue but I am running the unofficial cm9.. good luck to us both and is it the same cable u always been using cause I bought 2$ cable off eBay it only charges no USB connection
Sent From Galaxy Bigger Than Yours.

I tried to re-install drivers and I'm using a known working cable - the one that came with the phone.
It really is strange. The only thing that has happened recently is my phone was rooted with Clockwork Recovery and then I reverted back to stock.
I'll see what happens after the ICS update comes from Telus next month, I guess.
Not a big deal as I can use AirDroid to transfer stuff over wifi.

Since rebooted a couple times now everything is working. I also had a problem with the lock screen rotating and phone defaulting to speakerphone. everything is back to normal now but i wish i knew what caused it.

USB BROKE. Need to Update OS!

First off i rooted my phone and had a custom stripped official OS loaded. Worked fine.
After about 8 months my USB had charging issies (had to wiggle cord to make it work) eventually it quit all together. I had the USB port repaired by a tech. My charging works now. BUT Ive had random issues with the phone so one day i decided to update to the official software, and didnt want to bother with custom OS's anymore. I plugged my cable in the computer to use Odin and flash an official T-Mobile OS so then it would overwrite the rooting and get me back to where i could update OTA in the future.
Well, the USB no longer connects to computer. Not by different cables, not to different computers, not by different ports, not by storage mode, not with or without USB debugging, not by uninstalling the USB in the computer for the drivers to reinstall and not even with updated Samsung drivers. It will ONLY charge. NOTHING recognizes it, not Windows 7, XP, Keis, Odin. It doesnt even ding when connected.
So im left without UBS connectivity. I downloaded the newest OS for T-Mobile, put the SD card in my computer and moved the .zip there, then tried using the CWM i had from the custom OS and Root to apply the update via SD .zip file. It wont install it.
[EDIT] One more thing... I can get into recovery mode but NOT into download mode (as the USB wont connect) the phone just vibrates and restarts normal booting.
How can i install firmware without USB/Odin/Keis?
Wifi internet sharing, hotspot, remote desktop, blutooth, sd card? anything?

If you still have a custom recovery, should be able to just grab one of the stock firmwares that are put into a cwm package and be good to go. Often people stick them up here when released so others can get them too.
