[sane-devel] USB scanner and mounting usbdevfs with devmode 0666

Hi,
I'm normally testing my (usb) backend on the following systems with different 
access methods (scanner module/libusb):
SuSE Linux 7.3, kernel 2.4.17 (updated)
SuSE Linux 7.0, kernel 2.4.16 (updated)
SuSE Linux 6.4, kernel 2.2.20 (updated)
Caldera OpenLinux 3.1, kernel 2.4.2

While it's possible to mount usbdevfs with devmode=0666 (the number of the 
beast ?:-) on all SuSE system, it fails with Caldera, i.e. permissions still 
look like this:
-rw-r--r--   1 root     root           18 Oct 24  2002 /proc/bus/usb/001/001
-rw-r--r--   1 root     root           18 Oct 24  2002 /proc/bus/usb/001/002
after mount -av returns
...
none on /proc/bus/usb type usbdevfs (rw,noexec,nosuid,nodev,devmode=0666)

Does someone else have the same problems (maybe with other distros) or knows 
what's causing this? Or is this maybe just a bug in Caldera 3.1 ?

Thanks
Michael
