Re: m8xxhci USB host controler on FADS823

There is a later (and much better) driver on my web site.  Send me
email for details (don't want the .  I've been testing on the
BrightStar ipEngine.  It should work on the EP boards also, but I
haven't tried it yet.

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
        usbdevfs
        hub
        hid

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.
