I have the same problem. Dell inspiron win 7 home premium 64bit. Last week tried to connect galaxy (Android) tab to copy files. Done this many times before no problems. But now the tab is not recognised (still charges). Yest tried other Android phones same problem. Reinstalled drivers and restarted multiple times w no success. Upon checking driver installation status, showed installing HP B110 (my printer), which failed. Puzzled but thought Ok, I'll unplug my printer USB and while I'm at it unplug all USB devices, the only other one was the wireless keyboard n mouse USB. Ran reinstall Android drivers and got Err msg for printer AND wireless keyboard and mouse. All failed. Now the bloody keyboard n mouse don't work. Ran hardware device troubleshooter many times. Same Err, can't find driver for printer (which still works Btw) and installation failed for wireless keyboard and mouse. Tried to reinstall keyboard and mouse driver from device control panel, and got the Err msg 'windows found software for your device but couldn't install it. USB composite device. Access denied'
Can't use keyboard or mouse. The pc is touchscreen hah
