So this weekend I was toying around with the idea of rooting and hooked my phone to the pc for the first time in a good long while(I use Airdroid to sync files through Wifi). Each time I connected I kept getting the error message about the drivers as well as HTC Sync not recognizing that the device was connected. The phone will still show up on the computer to transfer files and such though. I'm running Windows 7 64 bit.
