HTC 8125 / 8100 / MDA (USA) / K-JAM / P4300 (Wizard)

I have had my 8125 for about 1 year now. I have never had any syncing issues until know. Activesync is not recognizing my phone all of the sudden. I uninstalled Activesync and reinstalled 4.5- no luck. I checked all settings on my phone (sync w/all PC to this connection & USB is checked). I connected to my work laptop and the same issues. Last time I synched was about a month ago. When I check the device manager on my PC the phone does show up under USB device and I note that the power icon is listed on the phone. I called HTC their solution was to remove and re-install activesync from pc , remove all sync relationships from phone and retry- didn't work. Any ideas out there? Anyone else have this happen? Thanks
