im running the code below, what happen is that out packet seems to work(
it returns from wp.asyncSubmit(wrp); wrp.waitUntilComplete(); // i've
tried
wp.asyncSubmit(wrp) before) but unless wp.abortAllSubmissions(); i got
exception trying wp.close();).
The real problem is that i cannot recive data from the IN endpoint and
rrp.waitUntilComplete(); waits forever.
I've tested the USB protocol and the data sent in ep1 (OUT) are correct,
in anycase i'll get a answer for errors.
Thanks in advice,
