Can not connect to PC. Only battery charge

[upirish22]

Help!! For some reason my mogul will no longer communicate with my pc. It will only charge the battery..nothing else not even recognize at an external storage device. I tried to re-flash but the ph pc will not even detect the device when it is in boot loader screen mode. I have reformatted pc, and reinstalled wmdc but still no connectivity establesihed to any pc....only battery charging works. Any ideas...It seems this problem started right after I tried to use internet connection sharing and tether it to my laptop. Is there a registry tweak or something I can do to get this connection established? or can I flash from the sd card? Any help is appreciated. Thanks.
