Hi all,
I am trying to use Brad's HCI driver (m8xxhci.c) on my FADS823 board. I have
some modifications in m8xxhci.c to adapt it to the FADS board.
When linux boots, the following messages appear:

It seems everything is OK because it detects a device (usb bus: NOT idle),
but it doesn't recognize de device (usb.c: null device being checked!!!).
If I mount usb dev file system I see that it is an error when I try to read
devices:
# mount -n -t usbdevfs /proc/bus/usb /proc/bus/usb
# ls /proc/bus/usb
001 devices drivers
# cat /proc/bus/usb/drivers

It is clear that it doesn't understand something. What I am doing wrong?
If someone knows what I am doing wrong, please help me.
Thanks.
