It can be something else (buffer overflow)

I get this error with the latest firmware whenever I click on "Get settings" in Megadrum controller.
What does that mean? Also, I can't seem to get my megadrum to communicate properly thru USB. Is the AVR-CDC really unreliable? Do I need to convert to PIC18F2550?

I haven't used MegaDrum with AVR-CDC lately so I'll have to test it tonight again. AVR-CDC is really a brutal hack for USB. I'll probably remove this USB board from the description. If you can do it I'd recommend you to switch to Synthex's true USB MIDI board.

I just tested it with FT232 USB Board, Synthex's USB board and AVR-CDC board and I must say AVR-CDC is having problems. In my case
MegaDrum Controller doesn't experience any buffer overflow but whenever I apply settings to MegaDrum with AVR-CDC USB board it causes MegaDrum to reset(you won't notice it without an LCD) which means AVR-CDC corrupts data when it is transmitted in bulks (like with Sysex messages). I'll try to play with it to see if anything can be done about it.

Ouch!
That sounds bad! I've already ordered my PIC18F2550 but since it not here yet I'll just wait if there are any developments.

I might have misjudged AVR-CDC. This thread is locked. See follow up
