It waits about 5 secs (timeout=5secs) seems like all is ok.

after I press CTRL+C device is present //// in devices file..
if I rerun the prog it start again with one timeout and subsequent
errors (libhid: interrrupt read failed)...

As a notice: sometimes device really reinitializes especially after
calls to hid_get_input_report or feature report (which it doesn't
support) with bad params...

I receive at first (libhid: timeout)
after: libhid: interrrupt read failed.

Besides I have:

hid_set_debug(HID_DEBUG_ALL);
hid_set_usb_debug(5);
hid_set_debug_stream(stdout);

so all of the errors I've already mailed...

Best regards, Serg.
