   Just a guess, but does you home-brew kernel have have USB support built 
statically (ie, non-modular)?  If it does, the RH init scripts see that 
the usb-controller driver is loaded and assume everything is already taken 
care of.  That is, the init scripts don't even try to load the device 
support modules at boot time.  Re-plugging the device after boot will 
force the usb subsystem to load the appropriate driver(s).
   I ran into this issue with USB mouse on my laptop.  The solution is to 
either hack up the USB detection in the rc.[something] script, or rebuild 
your kernel with the USB controller as a module.  I chose the second 
option, as it makes upgrading much cleaner.

   Speaking of upgrading, Valhalla (Red Hat Linux 7.3) is available for 
download starting today.
