Beats me, it works for me with the CVS version. Try killing the hal
daemon (pkill hald) and run 'hald --daemon=no' as root and post the
output if it doesn't work. Also try using hal from CVS and run as root

 HALD_VERBOSE=1 hald --daemon=no

and see if that works.

Right, the CVS version is wrong; it should be usb_device. The spec at
http://freedesktop.org/~david/hal-spec/hal-spec.html also needs to
update; I'll look into it.

Btw, I've made a small callout, hal-hotplug-map that reads the
files /etc/hotplug/usb.usermap and /etc/hotplug/usb/libsane.usermap and
automatically tags the device with the proper capabilities for devices
driven by libgphoto2 respectively libsane user space drivers. This is in
CVS under tools/linux.

Cheers,
David
