Still that is not an option. However can not find anything wrong, it seems to be electrically good when measuring all routes around USB, nothing seems to be wrong or even can not suspect any routes.... error on the pcb. If not ... that is not an option.
However, I have one question, what should one see on D+ and D-?
Now those seem to be steady, about 100mV.
Darrel: that software you kindly provided as a hex-file... When not knowing what is inside I'm not sure about what I should see on those two pins (23,24)?
