err... no thanks that wasnt really what i was after. by not using devfs
you really missing out on some fantastic features of a modern kernel.
static device nodes in the filesystem are a burden nobody should have to
bear... never mind the reduced overhead in registered devices which the
kernel now enjoys :-D. trust me, dont be afraid... give it a go! my
problem wasnt even devfs related in the end, in fact i have had next to
no problems with devfs.

yes, a silly question :-D it is of course as a module and not built in
at all. There is no problem if it is built in, but i rather have as many
modules as possible in a kernel config.

yeah... its very strange _why_ it doesnt pick it up... i fixed this in
the end and allowed auto-loading by adding this in my /etc/modules.conf
(first line is the important change from before, which i personally
think should be a standard /lib/modules/2.4.20/modules.dep entry)
probeall /dev/usb usbcore
alias /dev/usb/scanner* /dev/usb/scanner
probeall /dev/usb/scanner usb-uhci scanner
which fixes my scanner issues, and to fix the usbdevfs issue, i made use
of the above and the redunadant first field in the fstab rules for
usbdevfs, by adding this line
/dev/usb /proc/bus/usb usbdevfs defaults,devmode=0777 0 0
so that when mount looks at /dev/usb, the kernel loads the usbcore
all works :-D
(1) Never draw what you can copy.
(2) Never copy what you can trace.
(3) Never trace what you can cut out and paste down.
