/*
* Quick and dirty hack to implement the HS Electrical Test
* SINGLE_STEP_GET_DEVICE_DESCRIPTOR feature.
*
* This code was copied from our userspace app "hset". It sends a
* Get Device Descriptor control sequence in two parts, first the
* Setup packet by itself, followed some time later by the In and
* Ack packets. Rather than trying to figure out how to add this
* functionality to the normal driver code, we just hijack the
* hardware, using these two function to drive the hardware
* directly.
