So I've looked through every page I could come across in google and every search result on this site. I've yet to come across anything that fixes this problem for me.

I have a Touch Diamond running GrooveRom5.

I've tried connecting this phone via activesync on Windows XP and also WMDC on Windows Vista with no luck on either. I've unchecked and rechecked the settings in "USB to PC". I've restarted PC and phone multiple times, cleared the profiles on both phone and PC. I've uninstalled and reinstalled activesync and WMDC on each PC as well. I've tried to open a bootloader and load the stock rom, which is unsuccesful because there is no USB connection. The phone will charge by USB though. There is no visible damage to the phone's USB port. I've tried 3 USB cables. I'm running out of options here. Anyone have any other ideas? Any help here is appreciated.
