As far as I know, in Fedora "nousb" is never used as a module parameter.
It came about because interrupt tables are sometimes bad and once
a request_irq() is done in an HCD, there's an interrupt storm. So,
the "nousb" is mostly used in the SysLinux's command line, rarely
in the real command line, and never in /etc/modprobe.conf.
I'm adding Jeremy to cc: for confirmation.

I think it would be good to try and drop "nousb" option in Fedora 11.
The conflict with "nousbstorage" would resolve itself too if we do.
