Hello All.
currently we are trying to use an HD usb device. The problem is the
following:
- The first time the (attached) slightly changed version of
test_libhid.c is run, there is no problem, the device is connecting and
the communication is possible. When the test programm is run for the
second time most of the time we are unable to connect to the device. The
only solution is unplugging / plugging the device.
Resetting the USB device using libusb also does not solve the problem.
Debug output of libhid and libusb does not give me any clue what is wrong.
When pressing control-c during the execution of the program we are able
to restart the programm without any problem multiple times.
Does anyone have a clue why the program is behaving this way ? Currently
I am clueless.
Kind regards,
Johan Uiterwijk Winkel.

Hi,
don't know anything about this per se but you would get a better
response from libusb-devel list than from libhid list as I do not
think this can be a libhid problem. IIRC someone asked a about a similar
problem not long ago on that list, so searchin the archives might
be useful.
