Similar problem has been "resolved" by skipping the USB String matching 
sequence in libhid.c :  match_function_exact()
The "Device Match" is therefore only made on Vendor and Product IDs.

Of course, this is only a workaround ;-)
This problem appears also on a kernel.org-based linux.

For information, here are the logs we had :
[root at xa000000 root]# newhidups -a ups_on_usb -DD

Hope it helps.
