major 442

[Marco d'Itri]

I just installed the Debian 2.6.18 kernel package and I noticed that it
repeatedly tries to load a major 442 module alias, which appears to be
used by the usb_endpoint devices.
Does anybody know why? I am not even using the USB ports.

grep 442 /etc/modprobe.conf

It doesn't matter if you are using them or not, they are being created
by the usb core for the next-version of usbfs.  They currently are not
hooked up to anything properly, but people are working on them to fix
that soon.

And the number is just a placeholder, it's not a reserved major number.

As for what is trying to load the module, I have no idea, it must be
some userspace tool...

thanks,

Found it... I had this experimental udev rule which puts the devices in
/dev/bus/usb/ and pcscd keeps scanning the directory every second
looking for Cthulhu knows what:

SUBSYSTEM=="usb_endpoint",      PROGRAM="/bin/sh -c 'K=%k; E=$${K#*_}; K=$${K#usbdev}; K=$${K%%%%_*}; printf bus/usb/%%03i/%%03i_%%s $${K%%%%.*} $${K#*.} $$E'", \
                                NAME="%c"
