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.
