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.
ehci_hcd
uhci_hcd
If one of them does result in your usb devices being recognised, add it
to /etc/modules.
btw. You don't have to remove the ohci_hcd, as they don't conflict with one
another.
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.
Nigel.
