ok i don't understand how a radioshack charger works and the htc one doesn't. they are the same, its usb and there's not much that can change (unless you have an apple product where the charging requires a data connection before it charges). so it could only be the wall charger itself...but that should have nothing to do with you pc connectivity problem.

now i know i saw an option where you can pre set it to "disk drive" when connected to a pc, possibly in power settings, don't have my phone with my so can't check. but i noticed when i had mine set to this it would not active sync, not sure about not charge, never checked that. so make sure you don't have that setting applied then you should be able to active snyc. but the fact that a radioshack charger works means your phones port is most likely not the issue
