I've been looking at this today.  I've changed my hplip patch so that it
uses some of the existing hpmud machinery to fetch the Device ID using
libusb.

Could you try again with CVS revision 1.3 of
devel/hplip/hplip-device-id.patch?

http://cvs.fedoraproject.org/viewvc/devel/hplip/hplip-device-id.patch?revision=1.3

Yes, it's possible.  Is that actually what the problem is?  Can you look
with strace (i.e. strace -f cupsd) to see?

Which rule sets the permissions, anyway?  Is it 70-acl.rules
from /lib/udev/rules.d?  Perhaps printers.rules ought to be set later
than that (although since 'p'>'a' it already should be).

Thanks for helping out with testing.

Tim.
