[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.

Pc not detecting android but charging

Hi Basically plugged my S4 i9505 in via usb. Nothing shows in my computer, but phone remains charging. I have tried uninstalling and reinstalling all samsung usb drivers but it does nothing. Tried installing kies/older usb drivers, still no luck. Regardless of if there are drivers or not on my pc, there is no detection what so ever. My pc is detecting my second S4 I9505 perfectly. Anyone know the solution to this?

Tap 5 times buildnumber in settings menu under: about phone to open developer settings. Enable USB debugging. Now you can choose what to do when phone is plugged in pc.

USB debugging is Enable still nothing happen

USB debugging is not required in order to have the phone recognized by the computer.
Have you tried different USB cables and USB ports? Is the phone detected on other computers?

i had the same problem.... and we found out that the pins or the usb connection sh1t from the phone doesn`t make good contact. si try to push a little but or force up and down the usb cable to the usb from phone maybe you will manage to find a stable connection or something.
when i connect to phone to the pc i have to hold the usb cable connected to the phone in a weird position. that works for me

I had the same problem and I had to replace my usb port (the whole thing including the microphone). It cost me no more than 6€ on amazon. But before replace it, check if you have the port a bit rusted or dirty and reboot the phone a few times and then plug it again.
In my case, apart from that problem, I had other problems too, a few kernel wakelocks related to the usb that didn't let the phone to get into deepsleep. Sometimes after charge the phone and unplug the cable the phone shutdowns itself, etc.

It´s a driver problem in your windows OS, go to settings, system, about system, info system, device administrator, and go to android Phone. Change or update driver, select one in your system, select one of a list, and choose adb driver.
Works for me.

Zenfone 5 t00j charging, but is not recognized by the computer

Hi all, I have bought a second hand t00j however it seems that when i connect it to the computer via usb, it is not listed anywhere, but it is still charging. I tried different USB ports. I have tried with one windows and one linux computer. The phone is in MTP mode, I have the latest intel drivers. It is not showing up in the devices tab on windows. I tried enabling usb debugging. I opened the phone to make sure the connector ribbons between the usb board, the sim card and the mombo are connected properly. Please help.
