Hi,
I think that your device is broken, and goes bad when it receives a
clear-stall request for the interrupt pipe. That is not very uncommon.
Could you be more clearer? I'd like to communicate this problem
to the firmware developer of PICKit 2 inside Microchip. Thanks.
Could you try the attached patch. Just apply the patch by hand if "patch"
won't take it.
The file in question is /sys/dev/usb/ugen.c .
After that, compile a new ugen module or kernel.
If you are using the "ugen" module, then you can simply do like this after
that you have re-installed it:
kldunload ugen
kldload ugen
--HPS
The patch works! Thanks a lot.

Thanks again. Now I also get the real pk2 application works
for PICkit 2.
