[Q] Connecting to computer with USB in KK 4.4.4 - Nexus 7 Q&A, Help & Troubleshooting

Hi folks I have a rooted N7 and have used plenty of different ROMs in the last 2 years. Since installing KK 4.4.4 I cannot connect to my computer by USB, neither Windows 8 or Linux.
OTG is working as I can access external USB cards, there is nothing wrong with the USB leads, needless to say I have tried different leads in different USB ports, the tablet still charges when connected by a USB cable.
In settings, storage has MTP activated, I have tried PTP and it still will not work.
In developer I have activated USB / Android debugging.
I am using multirom and have done so since it came out
My main rom is MAHDI 2.7
Secondaries areCM11 20140903 and pac_grouper-1-20140903
Any help would be appreciated.

Think it's solved
All my other Android devices connect with my computers by usb so I have to conclude that there is something wrong with the N& OTG port.

[Q] USB Mount or Mass Storage not working on MT4G

The probem:
USB Mass Storage not working in Recovery. I tried everything, reflashing different recovery but its not working, it doesn't give an error message. When card is not inside however it does complain. SdCard is fine because I can flash zips that are on it. Tested on both windows and ubuntu. tried another card as well
USB Mount doesn't work in CM7.2 or any rom or nand restore i've done recently. I had Insomnia at some point, then inferno, then cm 7.1, none of these restores work. Again here no errors, I do not even see the sign for usb detection. usb debugging is enabled/disabled no difference. phone however still charges though.
I'm on a trip right now, but I've not had the chance yet to get another usb cable but the two I have dont work.

He has tried two cables, so I would tend to lean toward the port.

i am in the same boat. looks like my charging port is bad. anyway to replace the charging port? i am not good with soldering
it's not ur usb port
it's htc.. htc devices doesn't support usb host feature.
If you have a rom and kernal that do support usb host then try powering the usb as the htc devices do not provide power out.. use usb Y cable

What? He isn't trying to host the connection. He is trying to use his phone as a USB mass storage device.
Where did you get USB host from in his questions?

Hi all,
I am having the same problem, except perhaps with a different cause. My user account on Windows 7 became corrupt and I can no longer log in, so I had to create a new one.
On the new account, my myTouch 4G is not recognized for mass storage/disk drive mode via USB. The USB cable does work, the port is okay, and I've used both with other devices. The myTouch shows as charging when connected to the computer. I have uninstalled and reinstalled all of the myTouch drivers, restarted computer and phone, to no avail.
When it is connected in USB, it shows as generic "Drive F" and is inaccessible. When I check properties it says mytouch4g. When I check "Devices" it is recognized as portable storage. I have tried with USB debugging on and off, and have set "connected to computer" mode to disk drive.
Any thoughts? I thought possibly loading the generic ADB driver again might help, but I cannot get to the stage where I can force it to load that driver instead of the HTC one.

The computer doesn't recognise nexus 10 on usb 3.0 port

My nexus 10 is only being charged when I connect it to my computer on usb 3.0 port, the computer doesn't recognise it as a storage so I cannot transfer files. My galaxy s3 is working fine with usb 3.0
They are both working fine on usb 2. Is that normal?
not normal, my Sony laptop with USB 3 port see Nexus just fine. Running all stock on Nexus. Weird.
I'm also on Stock rom, but the bootloader is unlocked and rooted.
Did you ever find a fix for this? I'm having the exact same issue after rooting...Tabelt and recovery work great only my computer is not picking it up as storage...
Not "normal", but quite common. It's not the Nexus 10s fault, USB 3.0 is very buggy depending on the chipset.

[Q] Nexus 4 gone stealth

... and is no longer recognized when connected to a computer via USB, meaning I can't return to stock to get ready for the Lollipop OTA.
Got a rooted Nexus 4 running the latest PA beta.
What happens when connecting to PC:
- On two different Windows machines: systray popup saying "USB device not recognized. The last USB device you connected to this computer malfunctioned etc.". In device manager it says "Unknown USB device (device descriptor request failed)"
- On elementary OS, based on Ubuntu 12.04: nothing, besides charging.
No USB debugging connection notification on the Nexus 4 either when plugging in.
What I've tried (USB debugging enabled, all relevant drivers installed):
- Settings > Storage > USB computer connection > check Camera PTP (used to be required in order to get an RSA key prompt when connecting to a computer, now it does nothing)
- Flashing latest stable CM to see if PA was to blame. Made no difference.
- Uninstalling device through device manager in Windows and reconnecting. No effect. Driver update doesn't work either, finds nothing.
- Using Wugfresh's Nexus toolkit to see if that worked, but that obviously doesn't work either when the device isn't recognized, same with the Universal Nexus Linux Toolkit on Linux.
- Scouring the net for solutions and coming up with nothing
I have flashed factory images before on this phone without problems. Should I consider it a hardware failure by now, or is this a known issue with a fix?
Try a new wire, different usb port on computer, finally look into cleaning your charging port on the phone/replacing it.

Tried three different cables, every port on two laptops, no joy - my girlfriend's phone connects normally.
Wouldn't replace the charging port, then I'd just get a new phone since it's a 2 years old Nexus 4. If only there was a way to flash the factory image using only TWRP.

Flash this in twrp http://forum.xda-developers.com/showthread.php?p=47476426
Sent from my Nexus 5 using XDA Free mobile app
Thanks jd1639, that seemed to be exactly what I was looking for -
- but then I had an extremely blonde moment and formatted everything in TWRP, wiping the ROM I was gonna flash in the process, on a device where USB file transfer doesn't work anymore
My phone is now a paper weight.
Have you tried the file manager in twrp yet? I've found it connects when nothing else will...

[Q] No usb after 5.0.2

Hi i have a nexus 7 (2012) everything was working fine until android 5. The device was slow and almost unusable. Then the 5.0.2 update came out and guess what? I updated it and now my laptop wont recognize the device so i tried a different cable and nothing. I plugged the nexus 7 in my second computer and nothing not even the sound that means you plugged something in the usb port. So i went to my brothers house and tried his computer.... the same... nothing. We plugged his nexus 7 (2012) 5.0.2 wich is the exact same device as mine and it works so we thought that it was the usb connector on the device and we switched my connector with his....NOTHING happens. computer wont recognize the device, no sound, no pop-up, no ADB detection. Does anyone have the same problem or a solution on how to downgrade 5.0.2 back to 4.4 without usb cable?
Thank you
Did you tried out to start n7 into fastboot mode and recovery mode?
Is usb not available also there?
fastboot and recovery mode also has no USB. absolutely nothing happens. when i connect the device it charges but the lightning icon does not appear on the battery in the status bar. and its not the usb port on the N7 i changed it.
?????????????????
Same here
I have the same Problem - a N7 GSM with 5.0.2 and no communication via USB.
I have tried different computers with Win7 and Ubuntu14.10. As well as differnt cables. (And all combinations of that work with my HTC M7, by the way)
Under Linux, not even lsusb shows the device, or dmesg shows any connection to a usb device.
To be completly honest, I did not give much love to my N7, I have been using it hardly. But when I did, I have been flashing some differnt Roms and testing different bootloaders so this might be some kind of my fault.
i updated to 5,1 and still the same problem so i assume its hardware related. but i know it is not the USB connector because i tried it on my brothers N7. and it works
Mine is quirky, comp recognizes it and can order boot but sideload and push to device don't work. Its odd.

Nexus 4 5.1.1 LMY48T not recognized by PC at all!

Hello everyone I've got an issue with my Nexus 4 which is why I registered, as I simply don't know what to do anymore.
My Nexus 4 is not recognized via USB at all, there is no connection sound and ist does not appear in the device manager.
It is charging and does show USB charging if I tap the battery icon.
Things I tried:
Uninstall/Install Driver with and without WugFresh Toolkit (USBDeview)
different Pcs (different USB Ports)
different USB cables which all worked with other mobile devices such as Samsung S3/4/5 mini
checking and unchecking MTP,PTP and Usb debugging
fastbootmode
factory reset
replaced the USB flex cable as i figured it would be defect
I tried to root it with some of the apps available bur none of them work with LMY48T.
I think it might be firmware related but because I didn't flash a Custom Recovery the last time I rooted it I have no possibility to flash another rom.
The root access was lost when the last OTA Update arrived which is why I can't install a custom recovery via the clockworkmod Rom Manager.
The Pc I'm working with is running on Win 10 I'm running out of ideas.
Please help me, thank you
