My dku2 kernel module doesn't seem to work under 2.6.17.8 so I thought 
I'd try pkot's libusb stuff, since that is "the right way".  With the 
suse modified libusb I couldn't get the permissions to work (it uses 
resmgr) so I switched to a tarballed libusb-0.1.12.  With that (as root) 
gnokii --identify works but segfaults at the device close.  More 
complicated commands fail earlier at the second device write, but is due 
to the device data being corrupted (eg the endpoint is incorrectly 
zero).  Debugging got a bit tricky when I started getting dwarf errors 
when using backtrace in gdb.  Those seemed to be helped by using 
malloc'ed memory rather than "large" chunks on the stack.  That's as far 
as I got late last night.  I'll look properly when I get time...it's a 
64bit machine btw.
