Description of what is Happening:
With the cable connected, the phone starts to charge normally, but it does not warn that on a PC (to choose the USB mode), it still like it was connected in a normal charger. The computer recognizes that something was connected, however warns "Unrecognized device".
Things I noticed:
- In Bootloader mode, the last line, which was supposed to say "connected to USB", it says, "USB cable connect", like it was not recognizing the cable.
- Sometimes, and rarely, he returns to connect normally, and even moving the cable it remains connected, however, when i trying to remove and connect again, it comes back to the same problem.
- if i try to turn off the screen, open some app, or do whatever thing (even scroll down the topbar or open the drawer, the USB connection closes, only still charging. When returns to the homescreen, it tries to reconnect, but still unknown.
Since then I tried to do the following things:
- Uninstall and install the USB drivers from Motorola
- Restore Windows to an earlier date that the last given problem
- Test different USB cables (including the original)
- Connect in different pc ports
- Test the USB cable to other devices, and worked perfectly, proving that the problem is not the cable or the computer ports
- Clean the external storage cache and media storage and reboot
- Format phone (twice, the second by Recovery Mode)
- Clean the USB port of the phone
- Connect with the MTP mode on and off, and the debug mode on and off
And nothing of this helped me!
