Felipe,
I just checked your testing/next branch. 'git log' of that branch
doesn't show the complete commit log of this patch.

Two simple test cases for interrupt endpoints are added to the usbtest.c file.
These are simple non-queued interrupt IN and interrupt OUT transfers. Currently,
only gadget zero is capable of executing the interrupt EP test cases. However,
extending the same to other gadgets is extremely simple and can be done
on-demand.
The two new tests added are
- Test 25: To verify Interrupt OUT transfer
- Test 26: To verify Interrupt IN transfer
Since the default value of wMaxPacketSize is set as 1024, so interrupt
IN transfers must be specified with the size parameter = multiple of
1024. Otherwise the default value (512) in the usbtest application fails
the transfer. See [RUN 4] for sample logs
The application logs (usbtest) and corresponding kernel logs are as
following:
It only shows up to here. Rest of the commit log is missing.

I guess this is the culprit...

This code has been tested only with gadget zero and care has been taken so as to
not break the existing functionality. However, if anyone can test with other
gadgets then that would be great!
