Thanks for that.
I tried downgrading pyusb but it seemed difficult.
I tried changing fousb.py to use the new version of pyusb but it seemed
difficult.
I tried making fousb.py use the legacy interface to pyusb but that turned
into a black hole of pain.
So I hacked fousb.py to execute the yepkit command directly. yuck! but it
seems to work.
Thanks,
Don
