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!
