Try the upgrade procedure on another PC. If doesn't help, the only option I see is to send your MegaDrum to me to debug. PM me to arrange this if you want.

Make sure MegaDrum is shown in the Windows devices list.

Just for the info....

I've tried on 2 different computers running Windows XP, both detected a new device and showed "USB audio device" in device manager/audio controllers, video & games, BUT, in control pannel/Sound and audio/ there was no way I could choose Megadrum as the MIDI input or output. The main sound card was the only option.

Then I tried on a third computer, running Vista, and just like Windows 7, it automatically detected the device and appeared as an option in MIDI I/O of the firmware utility.

Conclusion...
I still cant update the firmware. The process remains at 0, exactly like it did when I tried at home
:(

kimouette, the board has arrived and I found the cause of the problem and fixed it.

PIC18F2550 was programmed with the old Synthex's USB firmware version and apparently it has a problem passing some Sysex messages from/to Atmega.
I have programmed PIC with the firmware version I developed and which is available at http://www.megadrum.info/content/downloads (direct link to the file: http://www.megadrum.info/sites/default/ ... _20MHz.zip).

After that the firmware upgrade process went flawlessly.
