I have been using the T100 only infrequently but it has always worked fine. Then recently I noticed the Keyboards USB 3.0 port just stopped working. No power, no transfer ability, nothing. Te rest of the keyboard works. I also noticed I can't uninstall and reinstall Windows 10 now either. Every time I try to do a factory reset of any kind it fails and gives up a certain percentage into the reset. Anyone know if my USB port issue is software or just a bad keyboard? Oh, I did check the USB drivers and ports and tried reinstalling, etc, and nothing works. They are all listed as fine and working. Any help would be great! Thanks!
