Sorry for the delay in replying.
There are 2 other host controllers you could try modprobing. I remember having
problems with my usb midi keyboard not being detected on one install (Gentoo
IIRC). One host controller was loaded, but I had to specifically load a
different one to get the usb midi keyboard detected. Try the ones below.
If one of them does result in your usb devices being recognised, add it
btw. You don't have to remove the ohci_hcd, as they don't conflict with one
Sorry for CC'ing you, but your post was a few days ago, and I'm not sure if
you're still reading the list.
