two usb issues, digital camera only as root and scanner module not found

i am running debian sid on a machine with regular usb ports (not 2.0).
i am able to use my digital camera through gphoto2, but only as root. i've searched all over and the only answer i see is "use hotplug". i do have hotplug installed and running but i can't seem to find out how to change the permissions.

as for my scanner, i've installed sane and done my modprobe scanner which returns:
# modprobe scanner
FATAL: Module scanner not found.

where/which module must i install?

thank you in advance,

Scanner module only works in 2.4 kernels, so if you have 2.4, it might not be enabled in the kernel. 2.6 kernels don't use "scanner", you'll need to set up your scanner with libusb. Ther'e more info here

About gphoto2,

in order to use hotplug, your camera must be supported bu gphoto2. Actually, if your camera is not explicitly supported, but supports either USB mass storage or PTP mode, you may still be able to use it. You have just to add the corresponding keys into /etc/hotplug/usb.usermap or into a corresponding map (I don't have my debian box here right now, so I cannot check).

You can find the corresponding keys by /sbin/lsusb. They were called idVendor and idProduct, AFAIR.

Well, there is another and easier and less secure way. You have to mount usbfs with write access to non-root users. Use sth. like

usbfs /proc/bus/usb usbfs defaults,devmode=0666 0 0

in your /etc/fsatb file. The devmode option givew rw access to everybody. Look for more options, e.g. corresponding group options may be handy. But beware, this does not work before 2.6.8, AFAIK.
