Ah, this is a very good observation of you! I did run a 'service ups 
restart', but the usbhid-ups process wasn't killed. I had to manually 
kill it. From now on, a restart of the ups service does restart the 
usbhid-ups process as expected. Perhaps I should have issued a 'service 
ups stop' before I upgraded from 2.2 to 2.4 as I expect that the 2.2 
/etc/init.d/ups would killed the usbhid-ups process.

Furthermore, the 'usbhid-ups did not claim interface 0 before use' 
messages now have disappeared. So also Arjen's advice to upgrade was 
useful :)

Thanks,
Mark
