Device Descriptor Request Failed: PIC18LF14k50 (mla 'CDC-serial emulator' example program)

Question

Allright hello guys

Been lurking around here some time.

I started playing on an online casino and i have seen all these thread here about card counting and all that and most people dont recomend playing online for profit but i would like a few opinions on this idea.

As title says i am playing BS to a decent level ( i am not certain for only a few hands).

Anyway, i started with a 20 euro bankroll (a joke i know) but managed to turn it into 100 after about 30 minutes and quit. After i left i started thinking how would i be able to turn that to a small profil over time see post. I am almost certain that with this kind of money there is no chance of going big, so i though i would try and play that 100 and see where i go. My idea was that anytime i got 30 euros of profit each day i would call it quits and go again the next day.

That way i wont

Dear all,

I'm having trouble with the CDC-serial emulator example program of MLA (version 2015-08-10).
I programmed it on a PIC18LF14K50, available on an own-made PCB.
Schematics URL:

When I connect the USB connector (after removing the programming connector) to the PC I get the error message that the USB device could not be recognized. Opening the device manager learns that the 'Device Descriptor Request Failed).
Error message:
Device manager:
What can be the problem? The PC runs Windows 8.1 Enterprise.

For another project about 2 years ago I also implemented a serial emulator starting from the MLA example software (don't know anymore which version). At that time it was working and I was using windows 7. But when I try to connect that device, which was working and didn't change any code, to the current computer with Windows 8.1, it is not working either. So I'm thinking this can be a Windows 8.1 problem, but how to solve it? Or is there another problem?
I already searched online for solutions but none of them have worked so far.

I hope someone can help me out.
