/*
Test HCD interrupt pipe URBs
Purpose:
- Test that an interrupt pipe can be created
- URBs can be created and enqueued to the interrupt pipe
- Interrupt pipe returns HCD_PIPE_EVENT_URB_DONE
- Test that URBs can be aborted when enqueued
Procedure:
- Setup HCD and wait for connection
- Allocate default pipe and enumerate the device
- Setup interrupt pipe and allocate URBs
- Enqueue URBs, expect HCD_PIPE_EVENT_URB_DONE, and requeue
- Stop after fixed number of iterations
- Deallocate URBs
- Teardown
Note: Some mice will NAK until it is moved, so try moving the mouse around if this test case gets stuck.
