Hi everybody,

Linux USB host support for the CPM, CPM2 and CPM2 pro is far
from complete. Many people showed interest on this list (and on
linuxppc-embedded) in the past, but nobody managed to complete a
driver and get it merged.

that is mainly because of its semi-software nature. However, any
approach would be helpful I beleive.

The CPM/CPM2 USB host controller does indeed put some pressure on
the CPU. The PowerQuick III family is much better in that respect
as its USB host controller is EHCI compliant.

I didn't yet compare with CPM/CPM2, but I wonder if PQIIPro (MPC8360E)
USB controller is similar to cpms?..

=46rom what I recall, it is similar, but ucc usb  should work fine,
at least according to RM it does all the necessary things in hw
so the cpu isn't hogged with say SOF generation.

I tried to forward-port FHCI from Freescale 2.6.11 kernels. Twice.
But these efforts always stumbled over more important tasks.
