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.

Yes, I just tried this. It still doesn't seem to work. It keeps saying my drivers are up to date but it's still not connecting to my USB storage.

[Q] USB and recovery problems after OTA upgrade to 4.3

I took the OTA to 4.3 on my Nexus 7. It was previously unlocked and rooted, but had no kernels, etc changed. After the update ran, I lost root as expected, however, in trying to get it back, I've discovered I'm having a couple of other issues.
First, the device is no longer working properly via USB on my PCs. On both my Win 7 and Win 8 PCs, the device won't properly connect to where I can browse files or anything else. On the Win 8 computer, I see a Nexus 7 device in Device manager, but drivers won't install. I downloaded the drivers from the Asus site, but trying to manually install them doesn't work on the Win 7 machine, and on the Win 8 machine, they install but don't seem to be working with the Nexus 7 as it still shows a problem in Device Manager.
The tablet also will not boot into recovery mode. I can power it up into fastboot mode, but if I select "Recovery Mode" and hit the power button, I just got the Android with the red triangle for a few minutes before it boots back into the OS. After doing some searching, I saw where you might need to have it plugged into a PC to get it to go into recovery, but that doesn't work, either (might be tied to the USB problem).
Ideas?

Did you turn on developer options, and USB debugging? Have you tried USB connection type PTP instead of MTP?
If you have the stock recovery, the red triangle and Android are normal. You can bring up a blue options menu by pressing the power and volume up buttons from the red triangle Android.

Yes.

Try another driver source. Wugfresh's installation is a lot tougher than Skipsoft's, but try the other guy 's system.

I was using the stock drivers off the Asus page. I'll look around for the two you mention. I assume they're posted on here somewhere.

And about the recovery just try flashing another recovery from fastboot

Without USB access? That's my dilemma.

OK, I'm getting closer. I got TWRP installed and rerooted it. I had to do the "Revoke USB debugging authorizations" on the Dev Options screen. Then it would work via ADB.
Still not browsing files yet on my desktop, but at least I know I'm talking to it. So now I'll play with the driver installation a bit.
EDIT: Well, drivers reinstalled for about the 4th time, and it's still not allowing me to browse files from my desktop. Galaxy S4 works fine as soon as I plug it in, even if I also uninstall it's drivers. Ideas? I obviously have it working over USB because I can give it commands and reboot it via the PC.

OK, try this one. Plug in your tablet to pc, go to hardware manager, find your Android Device then choose Uninstall (choose Remove all drivers for this device), unplug and plug in your tablet again. Your Windows should discover few new devices (mine has discovered three) and download drivers for them then you should see Android ADB Interface in Android Devices and Nexus 7 in Mobile Devices.
--edit--

After you plug your nexus in have you unlocked the screen to see if it is asking you to authorize the tablet?
What other steps have you taken? Have you installed proper drivers? Have you manually chosen to update drivers with the sdk drivers if in device manager is showing the nexus? Have you tried the drivers from Asus?

I personally did all of those things. After having the Nexus "forget" all the other PC authorizations on the dev screen, I finally got it to accept ADB commands, just not to properly install drivers that would allow me to browse files like it had done on 4.2.

Nexus doesn`t appears in device manager. At all. It starts to charage, but no reaction in device manager, no any reaction(except charging) at nexus. On computer it looks like i didn`t connect anything. I`ve trying to intall drivers as legasy hardware, but nothing changes. Sorry for my english.

Try turning off usb debugging. My tablet cannot connect to pc but with usb debugging off it at least recognises tablet as a media device and this enables me to view its files
.but still the problem of not being able to root

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

USB driver trouble

Ive been searching and trying for quite some time now for a solution but I have yet to find one.
My problem is this, I've soft bricked my Nexus 7. I can get into fastboot and recovery (CWM).
My computer has had a fresh install since i rooted last, now when i connect with USB it doesnt even come up in device manager. Everything ive found online tells me Windows will automatically detect the device then i can update the driver. But i cant even get that far!
I was wondering if anyone could PLEASE help me figure this one out? Is there some way to force Windows 7 to install a USB driver for Nexus 7. Ive downloaded the specific driver.
I'd hate for my Nexus 7 to end its life this way.

Did you try with wugs toolkit. It should have multiple solutions for USB drivers.

I tried Wugs toolkit... also step by step, manually in SDK but Im always getting stuck at "Windows will automatically detect your device" because it doesnt.
the only solution i can think of is to get another nexus 7 to install the drivers and take it from there, but thats a leap i'd rather not take unless it's completely necessary. Even then there is no guarantee that it will work.

Are the latest chip set drivers for the computer installed correctly? All windows updates and drivers? Tried another USB device, cord, and port? Of the 5 ports on my laptop only 1 works for adb and fastboot.

When using WUG's Toolkit be sure to use the USB deview tool inside the driver section.. Remove all of the entries with the Vendor IDs listed in the tool dialogs.

Interesting that some of you have been able to get adb working. I've tried every possible USB drivers and cannot get adb working for my nexus 7, nexus 10, or Acer iconia A1-830. My phone still runs android 4.2, connects no problem. There is no solution, must be because I'm still running winxp on laptop

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/
