Lost USB Connection

[BuffaloBill23]

I have a HTC Touch running on the Sprint Network. I have never had a problem with my USB connection. However, since about a week ago, I can not connect the phone to the computer with the USB connection. Active Sync does not see the phone as connected. I cant see the device in My Computer. I have tried to use the tools in Active Sync to diagnose the problem without success. I have tried differnt cables and I have tried 2 other computers. I get the same results. I tried a soft reset, powering down the phone and removing the battery. None of that fixed the problem. I tried reviewing all the settings on the Active Sync program on the phone, unchecking and resetting them all. Still didnt work. I called Sprint tech support and they had me uninstall and reinstall Active Sync on the computer. That didnt work. I havent tried a hard reset. I am trying to avoid that because I dont wont to have to reinstall all my programs and customizations.
I would appreciate anybody's help
