I recently updated my phone (Huawei G7) to android marshmallow 6.0.1. Everything was fine at first but after a few days, I realised I can't connect my USB stick (micro USB flash drive) to my phone. After that, I connected my phone to my PC and I got nothing!
My phone doesn't charge when connected to my PC and my PC doesn't show anything when I connect the USB cable. Huawei software also says no device connected. I tried different cables and the result is the same. I factory reset my phone, now it charges but still nothing shows up ion my computer or phone.
I enabled USB debugging. I used to get a message prompt on the phone to allow connection to my PC. But now there is no such message and there is no USB debugging notification in the notification bar.
I changed USB connection mode to Charging Only, file transport and photo transport. But it doesn't make any difference. It's as if my phone is not connected.
I feel like android is blocking the use of the phones USB port except for charging.
Does anyone have any idea?
Does your PC makes any sound on connecting your phone to it?

Can plug into computer fine, but when plugging into other devices via USB to play music the device detects the phone for a couple of seconds then disconnects. Tried different settings within the Settings > System > USB Settings, still the same issue. It used to work fine until recently.
Are you sure you're using Disk Drive mode? I've never seen it disconnect spontaneously. You may want to try a different cable.
Cable seems to be fine as it works perfect when connecting phone to computer. It connects the screen displays asking what mode, then disappears too quick to select anything as its disconnected.
Hi there,
since yesterday I have really weird USB connectivity problem - my computer doesn't recognise the phone - neither as MTP nor PTP device. I flashed two different customs and one stock rom and still nothing. Also changed my USB cable, turned Debugging on and off. It only charges now and the phone still knows that it's connected to the PC, because it requests removing the cable in order to toggle debugging.
Any ideas?
Hello Everybody
I have this strange Problem , When I plug my Razr XT-910 To my PC , after enabling usb debugging it works and it is identified among the drivers,
but after a period ( 5min) My PC connection gets disabled but windows cannot detect any problem,
the web sites just don't respond while Connection icon shows it's still available and other PCs In my house work just fine.
I disabled MTP Mode and decided to use it under mass storage mode and it worked without this issue
what is the probelm and how can I fix it ? My PC Spec :-
Phenom II X4 955BE
ASUS M5A99FX Pro R2.0
8GB Ram
My Razr :-
Running ICS , Stock , Unrooted , Middle East region

It sounds like your PC is trying to use the phone as a modem, i.e. USB tethering. The PC routes packets out to your phone instead of going out over the ethernet or WiFi connection. Your carrier is probably blocking USB tethering, so you get no internet on your PC.
Disabling MTP disables the USB tethering, so that is why the problem goes away when MTP is turned off.
I can't verify this solution, but I would try to disable USB tethering. On my phone (stock verizon version running 4.0.4) this is done under settings/techering/enable USB tethering, which you want un-checked. I think this option is only available after you are plugged into PC.
After successfully rooted my device and have xposed framework and modules like gravitybox[KK], i observed that when i try to connect my phone again to any pc using my USB connector, it seems that the "USB connection mode" (where you be able to switch to another usb connection mode, for example, mtp to charging, charging to mtp) are not showing up on my notification area. I regret my self because the last time the "usb connection mode" are still working, i choose the charge only. And when i try to connect again, i can't switch anymore. I also try to add some code related to usb connection in my build.prop but it didn't help. Any solution to this problem? Anyone out there have strong solution pls share. Thanks.
Hi
I connected a USB flash drive through the otg to my type c port on my samsung note 8 phone. After removing the otg , the "usb charging connected device" mode is constantly on and does not charge the phone that connects to the charger and now for charge the phone, I have to connect the phone to the charger when it's off and then turn on!
