I've had it working for a long time, then my PC quit recognizing my N7 2012 intermittently. I thought it was a buggy ROM so I tried another. Same problem, so I wiped it and flashed stock 5.0. Same problem
It doesn't recognize it at all anymore, but I can plug in my N5 and N9 and they work great. Has this happened to anyone?

Did you try reinstalling the drivers? Download official Google ADB/USB drivers and install them through Device Manager.
Yep, did all that. The same driver runs my other nexus devices fine. I wish I could remember what the Windows error message says...something like 'unplug and plug it in again, if that doesn't work then replace the device'.
Make sure you enable USB debugging on your tablet. And first time you do that and connect it to PC, it should ask you for sth like RSA fingerprint. Accept that and it should work.

I see where on a lot of replies that the tablet needs to be in USB debugging. If it's in boot loop, how can you do that? My Vista won't even recognize the tablet any more!
Ok it started working again, so I quickly downloaded the 5.1 image to flash. I got through it but now it just shows the google logo forever. I can get into the bootloader via the hardware keys, but the n7 isn't recognized as a fastboot device, so I can do nothing else with it....
What Windows tells me when I plug it in is this: "The last USB device you plugged in to this computer malfunctioned, and Windows does not recognize it"
In device manager it says this: "Unknown USB Device (Device Descriptor Request Failed)"
I can get it into recovery, but it just shows our little android friend laying on his back with a red triangle.

Try getting into Fastboot. Hold Power button to turn it off. Hold Power + Volume Down button to get to bootloader. Try using Nexus Root Toolkit when you get there or try getting into recovery and flashing something.

Why can't you get into the bootloader with the hardware keys? To get into recovery in your situation, Hold Power Button + Volume Up(for one second only) and the recovery should pop up.
I can get into the bootloader. Just can't get the device to be recognized bu the pc, so O never succeed at flashing anything.

Try using a different USB cable or port, or even try doing all this on an alternative PC.
Its the same on my laptop and desktop, all usb ports, 3 different cables...
I'm starting to think the n7's usb port is going bad perhaps.

I have HTC HD2,I was trying to upgrade to Android, I think I made a mistake I installed “MAGLDR113” before upgrading my Radio to version 2.15.50.14. After I installed MAGLDR113 I connected my phone to my computer and the telephone was stuck in boot mode and was never able to see USB connection. Now my computer does not recognize my phone anymore and I can’t flash a new Radio version since I have no connectivity to my computer. I tried several things but all was useless. Can anyone help me telling me how I can have a USB connection to my computer??
Thank you.
do you have tried to start and hold volume button... than connect to usb and simply install a stock rom (for example from your provider) - this must work... if not - you have bigger problem.

Answered so many times. turn your phone off then turn it on "while holding volume down.It will then take to bootloader(rainbow screen).It suppose to have a cotulla written above the rainbow screen.Now flash it with a stock rom came from HTC site..No need to sync your phone to your PC..Just flash it..Start all over again..Now you can search before doing somehing with your phone.If that didn't help you. You have a bigger problem..
Yes I tried this also but it doesn't work.
What didn't work? Can you boot into bootloader - ie switch off, press and hold vol down button and switch phone on.
You should then boot into a multi-coloured screen and should see "serial" at the bottom of the screen.Then connect device to usb port (preferably one at back of your pc and a different one that you haven't used before if possible) - let the drivers install if applicable - does "serial" change to "usb"?
Do wat d above posters have suggested then try different usb ports or even a different windows pc...For all we know, your usb cable might be faulty....Also did u perform HARDSPL before anything else?
I've started experiencing this very same thing. HD2 wont regognize usb connection while in bootloader screen. I get the usb connection sound but never says usb at bottom of screen like it used to. I've been trying android builds via sd but wanted to try my first flash but cant even instal MAGLDR cos it just fails at bootloader cos of no connection. Has been driving me wild for 3 days now.
try plugging the phone into a different USB port it should work then...
Tried that all day and it said couldn't install drivers, then just tried the same ports now and its worked. I think it was mobile device center had 2 set-ups for my phone, i deleted the older one and all seems fine now.
This is crazy, now i'm stuck on magldr and won't find usb.
I'm leaving nand now cos i'm close to smashing my phone to pieces, magldr usb flasher will not find the connection no matter what i try, so i'm staying with ****ty windows mobile. Not happy but i've been trying for days now.

I am experiencing this exact same problem. Bootloader wont recognize the USB stays in SERIAL. Tried different ports, cord is fine. What is the problem.
Before this, my HTC HD2 would just hard reset on its own ONCE A DAY! Why was it doing this?
Now it gets stuck on the white HTC loading screen. Wont get passed it. I used to be able to hard reset by doing the volume keys down and reset but NOPE... still wont load past that white screen.
HELP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Have you guys tried deleting the drivers using a utility like USBDeview? Try deleting anything that relates to HTC OR HD2, replug the phone in, re-install the drivers.

Of course it won't work without drivers. The computer needs drivers to communicate with the phone. In normal mode, unplug the phone, Google the application, download it, open it, click everything that has HTC or HD2 in it and click uninstall. Plug the phone in, let the drivers install themselves again. Try again.

Ok... i rebooted into Normal mode, downloaded the utility, did a search for "HTC" found nothing, did a search for "HD" found nothing. So i am now installing windows mobile center for windows 7 which should have the appropriate drivers.
Install Windows mobile device center 6.1, problem solved.
Sent from my HTC HD2 using XDA Premium App
I'm able to view through USBDeview that my HD2 is connected, however I'm unable to view/open it.. I screwed up by naming the 'temp' folder to 'copy_to_sd_root'..
The instructions confused me. I figured this was the folder that needed to be copied to the sd root... however when i rebooted the phone, I was unable to access it. Any recommendations?
SOLVED
I was overlooking the USB Flash option.
If you are still having problems, let your phone turn on(no multi-color screen), select: USB Flash, click the DAF.exe installation file, follow the prompts.
You're done.
I had this problem and I solved it disabling an option in activesync. I can't remember what was exactly the checkbox, but was in "options" and it said something like "allow usb connections" or something like this.
I just disabled it and rebooted the device holding volume down.
Good luck!
Make Sure Phone is not connected to PC
Goto cotrol panel in windows
Uninstall HTC BMP USB Driver
Uninstall HTC Driver Installer
Uninstall HTC Sync
Unisntall Windows Mobile Device Center
Restart the PC
start the phone holding power and vol dn and now connect the phone to PC. should detect and install the drivers and you should be able to see USB on phone screen.
if this does not work
Delete all the USB root HUB but keep as last option in device manager.
PS: This will cause ALL the USB devices to redetect.
Let me know if this works
Loaded Android on my HTC HD2. Had issues with android, so I went back to Windows. Used the following to load Android
SPL-2.08.HSPL
Radio that support 576 MB RAM
DFT MAGLDR Bootloader v1.13
ClockworkMod Recovery v1.3
Now want to load android ROM again, but USB port will not work when I power on phone holding down volume button. Goes into multi colored screen but I never get USB in the white field. USB works fine when phone is being charged. When plugged into USB port on computer when in Windows mobile, PC does not recognize phone. Searched forums and it seems like a lot of people are having this issue, but no one seems to have the solution to the problem. Was hoping someone could help with this. Thanks!
Are you sure you have Active Sync or Windows Mobile Device Center installed on your computer? You have to have the correct version of this to have the correct drivers on your computer.

Yes, I have WMDC installed. My bigger concern is why the connection will not change from serial to USB when I boot into the multi colored screen by holding down the volume button while powering on the phone. If I have the USB plugged in when I'm booting to the multi colored screen, it just displays a white screen where it should say serial or USB.

If I am understanding you correct if you have the USB plugged in when you boot to bootloader(multicolor screen) it only displays a white screen. Does it x the Sam thing if you boot to bootloader and then connect your USB cable? Also I reread your first post and I see you also say your computer does not recognize the device when you are booted into a Windows Mobile ROM and you plug the device in via USB. Now this is really not good as it might mean your micro USB port on the device nolonger is functioning for data transfer. I suggest you connect your device via USB and then go to Control Panel and open Device Manager and seecwhat your device is listed as there, post it back here in this thread too pleased. I have a feeling though that you are just having a driver issue.

If I boot to bootloader and and then connect USB cable, it stays on serial and never changes to USB. When I plug it into my computer, the light comes on to show it is charging, but the computer never sees it. Even if I scan for HW changes, it never sees the device. Windows doesn't make the sound it normally does when you plug a device in via USB.

I definitely think you are having a driver issue, try this if you do not have a Windows Mobile ROM on your device and see if you can do any kind of data transfer via USB. Try doing some file transfer on your SD card, if you can do this then yes you most definitely have a driver issue. I would then re install WMDC and then boot to bootloader and see if you get the USB in the in the white bar of bootloader that shows you have the HTC Sync connection.
Unable to do any kind of transfer via USB because PC does not see phone as being plugged in when I connect it to the USB. Storage on the phone does not show up under My Computer as additional storage when connected. Attempted to reinstall WMDC and it gives an error saying that it can not install the device drivers. You mentioned Windows Rom, phone is running Windows Mobile, if that is what you meant. Thanks!

Man in that case I hate to say it but it sounds like the two data pins in the micro USB have stopped working.
Have you tried another computer?
I did OTA update to 4.3 of my N7 3G which was rooted and unlocked (I know now I shouldn't have done it...).
I got an error at the end of the update (when was installing radio).
Rebooted, and got stuck in the google loop...
NOW, I CAN ENTER FASTBOOT MODE, BUT THE PROBLEM IS THAT THE USB DEVICE IS NO MORE DETECTED BY THE PC (I tried Windows XP, Windows 7, Linux), so I cannot re-flash it... It's not a driver's issue, because at USB level the N7 is not even detected when connected to the PC (for instance, dmesg shows nothing in ubuntu and windows does not "beep").
Is it possible that that was corrupted only the "USB stack" of the bootloader??? I could not find a similar issue in this or other forums (??).
Is there any chance to get the USB working again?
Is there any chance to send it for repair to ASUS (I bought it one month ago) with this described symptoms and with the "unlocked" icon on power on?
Is there a payed service to flash it with JTAG?
Thanks to anyone who can give me a clue...
Same problem - updated to 4.3 OTA today, N7 not recognized as an USB device at all. Still haven't tried on a Mac but I doubt it will be any different. The device isn't detected in normal mode or fastboot

I solved by sending it to assistance. Excellent service by ASUS... I did not have to pay although the tablet was unlocked/rooted.
Andrea.
since the new update to 4.3, N7 requires authorization with your pc before you can use ADB. I had this issue and had to go into developer options and click on the 'Revoke USB debugging authorization'. when I connect it to the pc again and ran adb, my N7 then asked for authorization to allow pc access. That restore my ADB.
Also make sure you have the lastest SDK installed on your pc too.
If you can enter Fastboot via pc you certainly can reflash it.

In my case (and probably the same for Colblooded) I got stuck with the N7 NOT BOOTING and NOT DETECTED by any USB host (tried also with dmesg on linux), so there was no chance to re-flash it. The only thing I could do was to send it to Brno for repair...

you said you could boot into fastboot, did 'fastboot devices' on your pc not detect it? Does it detect it now?

That's the point: I could boot into fastboot but 'fastboot device' was not detected by the PC (so I could not re-flash it). Now if I boot into fastboot the PC correctly detects the device...
What I find very, very strange is that an OTA update to 4.3 caused the USB port to stop working!! From what I read googling around, even with a problem during a system update going to fastboot mode (on + volume down) should always allow a connection to the PC for reflashing, or, at least, you could enter APX mode (on + volume up), which is an even lower level mode that is detected by the PC with different drivers (for direct programming, but need encryption key and SW not yet available for Nexus 7).
Maybe it was just a coincidence: an USB hardware failure just before I did the OTA update, which I realized only afterwards, when I needed USB for reflashing...
However the ASUS Service Repair Report states:
Problem/Symptoms: Pad Battery can't be charged. OS ERROR
Replaced Part:
ME370TG BAT COSLI-POLY FPAC
ME370TG MAIN_BD.1G/T30L/NFC
The first one looks the battery (????)
The second sounds like the mainboard...

Ok so long story short, i have a nexus 7 2012 which a rooted and installed cyanogen mod.
I was using it as a car install and works perfect, i'm using an otg cable to mount usb sticks, triggering soft shutdown and powering the nexus etc. So usb seems to be working fine.
Basically i removed the tablet it to modify the bootloader to turn on automatically with ac power applied, if the battery runs out i have to manually power on with button, but now i'm running into a problem.
Ever since taking the tablet out and trying to connect over usb, none of my computers detect the tablet.
I've tried different operating systems, drivers, cables etc etc.
Also changed from mtp to ptp in storage and also turned on usb debugging mode. If i connect an otg cable the nexus see's the otg and i can mount usb's etc.
So i thought i might try recover the nexus back to factory, maybe there was an issue with the rom corrupted etc, I've downloaded the original 4.2.2 firmware which is currently installed.
Booted into recovery and tried re-installing the 4.2.2 zip, it keeps aborting. A guy in work tried to use sideloader and connect via adb. no luck.
I'm not very familiar with the android platform so i've no other ideas what to do and other idea's how to recover now.
The guy i work with mentioned using a usb jig, would that be the way to go or can anyone else suggest some else that might help.
Thanks
Before you updated when was the last time you connected your N7 to your computer?
When you connect your N7 to your computer does it act like it is charging? Have you tried more than one computer? I had a similar problem with mine last year & sent it in 3 times. Asus replaced both the USB port board & the main board on different occassions. I suspect your mainboard might be faulty.
Does adb see the device

I last connected the nexus to the laptop a few monts back to load some music onto it, didn't have a problem. It's only been connected to a computer maybe 3 times. once to root/rom it then another few times to load music etc.
I can't see why the usb board maybe faulty as i can read data from a usb key when the otg cable is connected.
It's a strange one. You could be right, i might try pick up a broken nexus and swap some parts. Usb board etc.

I am having this same problem on my (unrooted) HTC One after attempting to "convert" it from an AT&T to a Google Play Edition device with the procedure described here.
As part of the procedure, I attempted to flash the stock Google Play Edition ROM using fastboot commands, but I got an error message. The instructions say to just try the flash again, but the phone no longer connects properly via USB (error 10) while in bootloader mode. While in bootloader mode, the phone indicates there is some sort of problem (a line showing the OS version is highlighted in red), and attempting to enter recovery mode does nothing but display a phone with a big red X in it. The phone seems to operate fine and responds to ADB commands when the phone is fully booted, albeit with the old OS (not Google Play Edition) still in place.
Any Android device could theoretically get in this state. We're sort of "paralyzed", because everything we want to do to regain control of the bootloader and fix the situation seems to require issuing fastboot commands from a computer connected to the phone while it's in bootloader mode. Yet entering recovery mode or getting a computer to connect to it via USB no longer seems possible.
I wonder if there's another way to issue fastboot commands without relying on the USB connection to a computer?
I own an LG G2, i recently got this phone yesterday from a person on craiglist. Don't worry i didn't pay him i gave him my older phone i dont use anymore. SO This phone is practically stuck in Firmware Update (As i read that post) , i spent about a day and half figuring it out and what happens is that.
I CAN get into recovery its TWRP v2.7.0.0 by Turning off the phone first and then Holding Vol UP, Power, Vol Down at the same time until the LG Logo comes up and then i am still holding them down, and it says Recovery Mode please wait and bam TWRP.
But heres the problem i can't mount my OTG and i can't ADB Sideload. So what do i do from here?? this guy rooted this phone and soft bricked it i think? and he wiped the phone but i also did when i had the chance and wiped it completly via recovery.
The only way i got into "Download Mode" / "Firmware Update" was to take the back cover off and unscrew a few screws on the side and unclip the battery for a few seconds and then plugged it back in and then I held the VOl UP button and plugged my USB into the phone and the other end is in my PC. My phone says "Download Mode please wait" and then prompted with the Firmware Update screen. BUT my pc doesnt detect the phone whatso ever and i've already installed drivers and etc from this forum ( http://forum.xda-developers.com/showthread.php?t=2432476 ) its the 2015 method that i downloaded.
so what do i have to do, i havent tried using different usb cables, the port seems fine to be plugged in since in TWRP it says 84+ so i meant its charging right? help me out guys idk what else to do or flash or anything.

I think the methods leave out that you need to change your phone to com port 41 on device manager > ports in order to be detected. Then you need to unplug it and reconnect to computer when the program shows waiting for device, with the phone in download mode already.
Also, to get to recovery you hold vol down and power, when the LG logo comes up release power and hold it again until the reset screen comes up.
To get to download mode you turn the phone off then hold up while plugging the USB cord in with it connected to pc... This launches download mode.

Well you see man , I cant change anything in Device Manager since my phone isn't being detected. It didn't install drivers fully fully since my phone isnt recognized. Even in TWRP or "Download Mode/ Firmware Update" Nothing happens no drivers installing or anything even but it does boot it up to that point....and its just normal boot up i see the LG logo and my led goes from green to blueish in a smooth transition and it doesnt stop until i turn it off. The method i got into recovery is holding all those buttons down its not a problem for me to get into it. I also have another problem it doesn't seem to want to mount my usb otg by samsung.
what do i do
So i tried the otg route but I can't mount it. I have everything connected and once I go into recovery to mount usb-otg, nothing happens.
I just need some way to get a ROM.zip in my phone
Computer does not recognize my phone.
Stuck at LG logo unless I enter recovery.
Sideload doesnt work.
OTG doesnt work.
I've tried at least 4 different guides with no luck.
Why don't you manually install drivers from online?

ive tried that already and it doesnt list anything from the LG folder.
I realized the phone will say start the adb sideload feature. so, when i put the "abd sideload file.zip" command on my pc i just wait a few minutes and it says daemon not running on port 5037 and then start successfuly and then error :device not found.
it can seem to reognize my device wether its in recovery, or download mode or fastboot mode.
Try again in other pc that has never been conected to an LG Phone before. It can perfectly be a conflict with drivers installed in the OS.
I've tried man
AFter i cleaned the usb port in one of the chats or forums, i waited a day ovbiously without turning on the phone and cleaned the usb port with alchohal and a q tip and i plugged my phone into my computer and my PC detected something but it only says "Unknown Device" everytime no matter what pc i use it says that. nothing else. but before that none of my pcs would detect theirs a phone plugged in at all.

No there is no problem with your USB cord or port. You need to do following steps.
