/dev/bus/usb/ has vanished under 2.6.22.1?

[ael <law_ence.dev@xxxxxxxxxxxx>]

I reported two days ago that libusb could not find an usb scanner when
run from a member of the scanner group, but that the scanner was found
when run by root. This happened under kernel 2.6.22.1 but was fine under
2.6.21.*.

I now discover that /dev/bus/usb/ exists and is populated under 2.6.21.6
but is not created under 2.6.22.1. I am hazy about how udev creates
these files, and now suspect that this is the root cause of the original
problem. I will need to read some udev documentation, I guess, but can
anyone confirm this or suggest what may be wrong.
