I'm sorry, I simply have not had time to look at either of these patches. The basic idea is okay; there's no good reason not to have testing available for interrupt endpoints. What happens if you try to run this gadget but the UDC can't provide more than 4 endpoints? Would it make more sense to have the new altsetting provide only the two interrupt endpoints?
