Failed USB?

[NosferatuOMeGa]

Maybe someone can help me out here...

I am having a problem with connecting my Diamond to my computer.
I've had the phone since release, have unlocked & flashed a number of times with no issues.

Now, I can't even connect to my computer (or another one...)
I get no popup on the screen of the phone or computer saying its been connected... It does not automatically goto disk drive or activesync.

I am leaning towards my USB port being toast, but I can still charge the phone...

Is it physically possible for the usb port to be able to charge but not communicate?
