I am having problem with my usb port. It always says Device cannot be recognized :(

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 :)
