It seems OHCI and EHCI support is commented out in:


And the files aren't there if you try to comment it back in.  So 
using FILO, it seems it's  necessary to use UHCI if I want the new 
USB stack, if requiring OHCI, I have to switch to the old (obsolete) 
USB stuff.  Switching back to the old FILO USB stack requires a 
code fix.  Looking at:

It seems that parse_device_name() always returns DISK_NEW_USB
and not DISK_USB, regardless of which USB stack was selected
in make menuconfig so subsequent call to devopen() will always 
fail to find a device.

I'm mainly posting this to try to understand what's going on,
and if I missed something.  It seems very few people are using
USB with FILO.  I really had to struggle to find the device
name I'm supposed to specify to boot from USB (uda), so 
I'd propose to put that in the README.

I can submit a patch for both of these, but I'm unsure how far 
it gets us!
