Where? Don't mix this up with the purb_t definition, that is a pointer to an
URB, and it is initalized with alloc_urb...
The p*-stuff is a bit Windows-like, but that's how Deti writes his programs...

It was the first driver using the URB-API, and showed how to reliably do
isochronous streaming and firmware downloading for EZUSB. It has no big
protocol overhead, and is therefore much simpler to understand than a driver
that also has to care about complicated protocols. Since Deti also wrote the
Programming Guide, he referred to that driver.
