Please help - flashing to 6.5 broke USB syncing

[katenok]

I tried searching for a solution to this but didn't find anything. I flashed my Sprint Diamond to MightyRom 6.5 kind of a long time ago. I don't remember exactly when, but in Settings->About the build is 23001.5.0.60 Mighty.

After I flashed, everything worked okay but connecting the phone to the computer by USB, the computer wouldn't recognize the phone. This didn't bother me too much because I was able to sync by Bluetooth which is my preferred method anyway. I only use USB to charge sometimes.

Now I want to flash to a different ROM, and would like to finally fix this problem. Can anybody help?

Thanks in advance!
