Hi,
When I use hid_get_input_report() on a device (with at89c5131), I get
the 'Broken pipe' error. On the same device, hid_set_output_report is
working great.
Guess I'm messing up some addresses. Can someone help me out?
And is there some function to read the paths (to use in the
hid_..._report functions) from the hid tree?
Thanks in advance!
Best regards,
Jacques.
