I am having problem with my usb port. I am basically trying to attach my mobile via USB cable but it always says device not recognized as in below image:
Universal Serial Bus controllers:
The device used to work fine previously. As can be seen in image above, when I insert the usb cable, it goes under Other Devices > Unknown Device
What I've tried
- Tried putting usb cable in other ports - same result
- Tried uninstalling all drivers under Universal Serial Bus controllers, unplugged everything and restarted
- Tried Microsoft Fix it (it said my windows version isn't supported :( )
- Tried unplugging laptop battery and all cables and restarted after half hour
- Tried updating drivers from dell's support site
- Tried Windows 8 refresh feature
- Tried disabling Allow this computer to turn of device to save power
- Tried disabling turning off device via Advanced Power settings
- Tried updating drivers via device manager automatically update option but it said it is latest driver already
- Tried connecting other usb cables with same result
Other Details
- When I put anything else in those usb ports, it works for example mouse
- Same mobile and usb cable works on others' computer
- If I put friend's mobile usb cable in these ports, it works fine
- Device manager says power required for usb devices is
0MA
Possible Hint
One day I booted my pc and it said there is no battery and when re-started it worked fine ever since then I have no same no-battery warning message. However, this usb problem I think has come up since then.
Had anyone had similar problem, should I change something in Bios ? is there kind of Microsoft Fixit utility for Windows 8 as well ? Overall, how do I resolve/get rid of usb device not recognized issue ?
FYI: I am using Dell Inspiron 15R 5521 laptop with Windows 8 64bit.
P.S: Please don't suggest solutions I've already tried listed above.
Thanks for the help :)
