Hello,

i have a problem with a uDMX device running at 5V. The device could not be recognized by Windows. The fuses are programmed like this http://www.indyblog.cc/uDMX/fuses.jpg . Is this not right?
I am searching for a problem on the usb lines but two zener diodes with 3V3 at D+ & D- should work fine?
My schematic is this http://www.indyblog.cc/uDMX/schematic.jpg

Any ideas?


best regards
Xaptor

Hi, sorry to bring up an old post, and I don't even know if you're still around, but I'm having the same issue, and I was just wondering what your wiring problem was.
