I recently had a USB power surge on my Windows 8 tablet Acer Iconia W700 And now my USB is no longer working. :/ I have tried unstailling the USB drivers but when it's finishing Unstailling all the USB drivers my Windows 8 tablet always becomes unresponsive and i had to turn off the tablet after by switching the hardware/physical on/off button. I really really NEED the USB 3.0 working again as i can't transfer my video clips for Youtube or backup my stuff. So can anyone help me please? I was thinking of factory resetting my tablet again but i can't do it because of the USB not working!! :/ This is the 1st time ever i had a USB power surge..
