No USB devices (xpad/xir) in MCE

[Radak]

I've installed MCE on my xbox and I am unfortunately unable to control it, because I have neither xpad nor xir working once it boots. (This same problem was described by someone else in passing in another thread.)

It seems my problem is one of lack of USB devices working:

Code: Select all

# cat /proc/bus/usb/devices
T:  Bus=01 Lev=00 Prnt=00 Port=00 Cnt=00 Dev#=  1 Spd=12  MxCh= 2
B:  Alloc=  0/900 us ( 0%), #Int=  0, #Iso=  0
D:  Ver= 1.10 Cls=09(hub  ) Sub=00 Prot=00 MxPS= 8 #Cfgs=  1
P:  Vendor=0000 ProdID=0000 Rev= 0.00
S:  Product=USB OHCI Root Hub
S:  SerialNumber=c5ece000
C:* #Ifs= 1 Cfg#= 1 Atr=40 MxPwr=  0mA
I:  If#= 0 Alt= 0 #EPs= 1 Cls=09(hub  ) Sub=00 Prot=00 Driver=hub
E:  Ad=81(I) Atr=03(Int.) MxPS=   2 Ivl=255ms

And that's it. It claims to see a hub (and only one, where there should be two) and nothing else.

If I boot the Gentoox Stardust CD, xpad works fine, and I find something very different in usbdevfs:

All devices are properly seen, including both hubs.

Both kernels have all the appropriate USB modules loaded (usbcore, usb-ohci, input, hid, keybdev, usbkbd, usbmouse, mousedev, xpad, joydev).

Any ideas?

Okay, I figured it out. I was neglecting to pass the kernel kbd-reset on the command line and that was apparently breaking USB.
