Tonight did some debugging on loading uhci / usb_keyboard.
For starters: it is confirmed that it is uhci where everything fails
so far as "insmod uhci; echo 1; insmod usb_keyboard; echo 2;
terminal_input usb_keyboard; echo 3" (as suggested by nyu on irc I
think) did not produce a single echo output.
I inserted some debug statements which so far led me to bus/usb/usbhub.c

Output.
bus/usb/uhci.c:661: at uhci init
bus/usb/uhci.c:663: at inithw
bus/usb/usb.c:36:device=uhci
bus/usb/usbhub.c:152:ports=2
bus/usb/usbhub.c:156:determined speed
bus/usb/usbhub.c:160:assigned device

These debug statements were all added by me iirc.
To see what I added: http://paste.debian.net/28056/ (usbhub.c)
http://paste.debian.net/28058/ (usb.c)
btw, did anyone notice that in usbhub.c it says "usb.c" in the header?
confused me for a moment.

As far as I can tell so far it fails to enable the port with "err =
controller->dev->portstatus (controller, i, 1);"
Why that fails I have no idea though, but I will try to continue with
it tomorrow.

Best regards, step21
