I'm running FC1 x86_64 and having trouble with the USB mouse in
the 2.6.3 kernel. I read that the problem is that RedHat/FC1 uses
usb_ohci for the usb mouse driver but 2.6 uses ohci_hcd. I found
ehci_hcd.ko and ohci_hcd module objects and installed that without
any help. I also tried modifying:

alias eth0 tg3
alias eth1 tg3
# alias usb-controller usb-ohci
alias usb-controller ohci-hcd

I looked at changing /etc/modprobe.conf.dist to adapt to the changed
name for the driver; fix wasn't obvious.

said he fixed this problem by setting up his .config file to build
the kernel with:


set to 'y' to compile the modules into the kernel to KISS.

Unfortunately this obvious possibility doesn't seem to be handled
will in user space and during startup the stupid module scripts seem
to get confused and think the modules aren't available and the mouse
fails to work. Insmod reports the problem, looks like mousedev wasn't
found, perhaps linking a few more modules into the kernel will do the

Another interesting point is that Fedora on the dual AMD64 MSI MS-9131
(Ver 0.B) hangs if the mouse is in the USB port but runs ok if it's
installed after the system is running. The 2.6 kernel also seem to
hang if the USB port has a mouse in it at boot time. It hangs just
after printing "ohci_hcd 0000:03:00.1: OHCI Host Controler". Looks
like a candidate for kgdb.

I was wondering if this might a problem with the Ver 0.B board or the
BIOS. The 2.6.3 kernel is also locking up after running for just a
few minutes but the 2.4 kernel bundled with Fedora for the AMD-64
runs fine.
