Hi everybody,
I have this problem with my MegaDrum module: I have built Synthex's kit and I'm using USB port. USB device is recognized in Windows as USB Audio Device and everything works. But only few seconds (about 5 or so). Then the device is disconnected.
When I set MIDI speed to 38400 the device is not recognized. When I connect module via MIDI cable it works perfect.

Yes I did. On my laptop (pc and laptop run win xp) it does not disconnect but when I run MIDI-OX it receives midi signals for 5 seconds and then stops communicating. Same thing happens in Reaper.

Check for short-circuit around 18F2550 and check your USB cable.
