The host controller drivers (HCD) and the whole host side USB stack
use a common 'URB-based' API. There are drivers (HCD) available
(at different states from operational to unfinished yet) for
OHCI, UHCI, EHCI, CRIS HC (ETRAX100), MPC850, isp1161 .
On the other hand there seems to be different individual approaches
on the device controller (DC, USB function) side. There are some drivers
available (or will be available)
e.g. Strongarm (SA1110 DC), MPC850 DC, isp1161 DC/isp1181, ...
from different developers that implements different functions
(Serial, Network, ...).
But there is no DCD (device controller driver)
API so far. So there is no direct sharing of the function driver code.
