Hi, just assembling the first units.. maybe too long ago, that I did it last time

OK. PC interface is running...
D1 is always on (of course..)
D2 is off
D3 is on
D4 flashes very short after 1-2 times after USB cable plugged in.. then is off for app. 4-5 seconds, then stays on.. -> PC interface says .. Interface not detected..?
Any hints, on where to search for faults..? CPLD is been verified 2 times.. ok. Ft245 seems to be detected ok.. What should it look like in the windows system/hardware tab..?
EDIT: Forget it.. found it.. I had a wire for L1 and the pad next to it.. but soldered just both ends and not the 2 pads in the middle.. now soldered all 4 points and it works..
Thanks, Peter
