I connected MD in USB for the first time and windows XP found new hardware. Megadrum at first, and then just USB audio device. After installing drivers, i got a message that hardware may not work correctly. I went to hardware/device manager and i found out that windows were scanning for new hardware continuously!!!! This loop stoped when i shut MD down.
Is this normal?

The crystal (12MHz)?

Problem solved... changed the crystal with a new one, and resoldered everything around the area of pic18f2550
