Hello, after 10/24/2013 (glitched update) my keyboard, volume etc stopped working. I did a full reinstall of OS and volume up + power button for a few seconds. Now volume button is working. Type cover keyboard is not working only the damn touchpad. In device manager i have exclamation mark - unknown device and it was Surface Type cover filter device, however, i couldn't install a driver for it from a Device manager. Sometimes install of the type cover filter device ends with error code 1 and sometimes it says it's installed (Tried manual and automatically from the internet), but in the device manager it still says Unknown and i am not able to use my type cover keyboard, besides touchpad. MS totally screwed up my SPro2 with that update. Any help would be appreciated!
