Description of problem:
(Opening a new bug per Ernie's request, rather than adding more to
125975 which has already been marked "closed".)


ehci-hcd fails to init on my system, as shown here (the same behavior
also occurs at boot time):

4# modprobe ehci-hcd
/lib/modules/2.4.21-20.EL/kernel/drivers/usb/host/ehci-hcd.o:
init_module: No such device
Hint: insmod errors can be caused by incorrect module parameters,
including invalid IO or IRQ parameters.
      You may find more information in syslog or the output from dmesg
/lib/modules/2.4.21-20.EL/kernel/drivers/usb/host/ehci-hcd.o: insmod
/lib/modules/2.4.21-20.EL/kernel/drivers/usb/host/ehci-hcd.o failed
