11 is the error code returned by the call to usbd_set_interface().
With the FreeBSD USB stack 11 means USBD_NO_POWER. I don't know if
it's the same with the HPS stack.
Anyway, since the pwcbsd driver was designed for the official
FreeBSD USB stack and not for the HPS USB stack, i can not really
help you with it.
In fact i'm surprised that you somehow managed to get the pwcbsd
driver to compile and run with the HPS stack.
