THANK YOU!!! I've been waiting for someone else to have the same problem!!! I'm relieved it's not just mine. I'm assuming you did a manual install also? Is yours rooted? One person suggested ClockworkMod but I'm a little nervous about rooting. I've been doing the manual installs but that's as for as I wanna go. I can't stand the idea of bricking my phone.

My phone is new out of the box!
I found that on two Windows XP machines USB storage doesn't work. I then plugged it into a Win7 box and it worked perfectly. I also used a different cable with the Win7. Try a different cable and try Win7.

I have Windows XP on my work PC and Windows 7 Premium 64 on my home notebook and the USB worked fine on 2.3.3. Every since I did the manual install of 2.3.4 the USB functionality is gone. I'm thinking maybe the ROM is used wasn't incomplete. It's beginning to look like the only way to fix this is to root my phone

FWIW I did the manual update (full rom) and USB storage works fine on my Windows 7 Ultimate x64 box.

Yeah, I'm thinking maybe the one I installed wasn't the full ROM. As soon as I see people saying it works great I go ahead and use it. Do you know of any possible fixes without rooting?

No first hand experience, but would it be possible to download the full rom and manually flash it again?

Trying to figure that out. I've been told try ClockworkMod and go back to 2.3 but I'm trying to do it without rooting.

Try a different USB port
If the update was incomplete, the update would have failed the signature check. The first time I connected my Nexus S after manually patching to 2.3.4, Windows 7 Professional X64 did not detect it when connected. I unplugged it and used a different USB port and it worked. I then tried the original port and it also worked. I would try a different USB port and a scan in Device Manager before changing the ROM.

I also have Windows 7 Prof. 64 bit, but switching to different ports didn't work. It won't install the drivers. What else could that mean if it isn't the ROM?

I had this problem immediately after flashing CWM.
I booted into the ROM, then, while the USB was plugged in, powered off the device, and turned it back on. It then seems to work everytime I turn on the device, as long as I don't boot into recovery.

Me too

I had a the same problem with my SGS.
The trick for me did: disable usb-legacy-support in your motherboard-bios.

Have you tried re-installing USB driver from the latest android SDK?

Kind of strange, it was working great yesterday and today couldn't connect. Right clicked on android_winusb.inf and selected install and it started working again. Not sure what could have changed from one day to the next. But at least I know what to do when it happens again.

Never tried that. Doesn't that involve rooting or unlocking the bootloader? Both of those wipe the USB storage.

Don't have a custom ROM. All I did was manual bootload 2.3.4 on stock Android. The weird thing is when it's plugged in(charging only) and I turn it off, it starts to power down and then freeze. The screen doesn't go black until I pull it out. Then when I plug it back in it automatically powers back on. Basically, I can't seem to plug it in while it's powered off.

I have no idea why but my suddenly works again. Im happy but confused

You shouldn't need any drivers at all for windows XP vista 7 ect. Mounting your SD card, using flash drives... all use the same USB mass storage divice driver built into windows.

[Q] TF101 doesn't connect with PC through USB

Hi guys,
After upgrading to ICS I've been unable to connect my pad to the PC. This is usually not a problem, but last night I needed adb to re-root it. Nothing worked, nothing connected. Tried installing drivers and the Asus sync, but no luck.
Is this a known problem? Anyone got a solution? I doubt it's the hardware as I connected a few days before upgrading...

Found a solution. Went into Settings->Storage and turned MTP off and back on.

THANK YOU! Everytime I plug in my ET4G to the dock to charge it that stupid MTP crap always comes up. Had no idea I could disable it. Thanks!

yeah, this doesn't always help... I had the same problem when i first got my TF101, and i tried all the tricks, the one mentioned here with mtp, enabling and desabling debug mode, turning off and on with usb plugged in, and some others i can't remember... nothing.
In case anyone else is looking for the answer and the quick tips don't work, what did it for me was installing Android Revolution HD rom. I've read that this problem could also be bootloader related.
Anyways, cheers.

How to connect an ICS device to your computer
Step 1. Connect device to computer via USB
Step 2. Set USB connection as Media Device (MTP) (p.s. if you use a Mac you need to download Android File Transfer)
Step 3. Disable USB debugging if enabled
I hope this helped.

when you need turn off MTP it mean your computer doesn't have driver.
If you need using MTP go to asus page and download driver. it's easy to install driver ^^...
recently I can't understand why same file but the computer at my office can't install that file instead other computers working normal... maybe my work place using old windows version...

Like I wrote earlier - mine was actually in MTP mode, but I had to switch to camera mode and back to MTP for it to start working. Thanks for the replies, though. Hopefully it will help some other people with the same problems

it took me months to figure that one out - even microsoft and samsung hadnt got any ideas
its because windows 8.1 has changed the usb stack and requires that all drivers be digitally signed and has an identifer that the bios can read
this means some old usb device didnt work unless they met condition already although new drivers became available for most things but for some reason samsung havent updated their usb drivers in years (May 5, 2011 is last officall release) so im guessing thats why it doesnt fully work in windows 8.1 and im sure the problem is because its not properly signed so the device fails to enumerate unless you do the plugging in another usb device
other old phones work fine like htc and new samsung phones also work fine so its properly just a strange issue with the way the galaxy y handles usb

unfortunatly thats the only solution iv found for windows 8.1 - if you restart the phone or remove the usb cable you have to go through the process again of unplugging cable plugging back in then plugging any other usb dongle in after - its the only way iv found for windows 8.1 to enumerate the device

MTP Mode not working

Hey,
So I got my D802 today and I want to do the whole Root, Recovery, ROM shenanigans.
But for the love of god I cant connect the phone in MTP mode, so I cant Root, nor install a recovery.
I cant connect to the LG PC Suite either.
Any Ideas?

what connection type are u choosing after plugging it into the computer? are u running Windows, Mac, Linux? Windows will work with mtp out of the box but I think Mac and Linux need phone drivers installed. Windows will need drivers when you're ready to "unlock" using adb.

when you first plug in your phone it gives you the option to install the drivers needed to connect in the different modes, if not on the top right corner of the menu with charge/mtp/pc software it should have the option to install the drivers

you never said what connection type you're choosing on the phone after plugging it in. there are a few options and change how the phone is seen by Windows. some options won't have it display as an mtp device or as a drive letter in my computer.

Really Weird
I'm having the same issue. I'm running OptimusG3 v1.3, I've never had an issue with it before, I used MTP to transfer files yesterday, worked flawlessy, now it won't. I was trying to map the G2 as a network drive, I installed LGPCSuite, a couple of other software that should be inconsequential, and suddenly my phone says connected as MTP, but my laptop won't recognize or show the device in My Computer. I get installing device drivers prompts, I used the hardware and devices troubleshooter which told me 'LGE Android MTP Device has a driver problem' and LGE Mobile USB Modem has a driver problem. Reinstall device driver -> completed, but still not fixed. I installed LG's universal uSB tool or whatever, no fix. I have no idea wth is up (It's not a USB debugging accidental toggle either). I'll try uninstalling PCSuite. I though it would be more useful

Tap on the "Charging mode" notification when your USB is connected and you'll get a pop-up that let's you select MTP mode.
Alternatively you can go to Device Manager and look for any error icons (think they're yellow triangles - been a while since I used a PC). Right click and uninstall all the offending ones, the disconnect and reconnect your device via USB.

In a lot of MM roms, you have to go in to developer options and select MTP under 'MTP configuration' in there. Even if it's selected already, tap it again and it should pop up asking what to do when device is connected on the pc. $5 says that does the trick. Easy but surprisingly tough one. One other problem I'm running into lately with the new windows 10 is that it has driver signing enabled by default and often rejects the driver you install or just doesn't use it even if it's installed. So if the driver is the problem (or more accurately windows 10 is refusing to acknowledge the installed driver), you might need to disable driver signing enforcement. Here's a link how to do that: http://www.howtogeek.com/167723/how...8.1-so-that-you-can-install-unsigned-drivers/
