Unfortunately, I have to take up this problem a second time. 
I considered the issue fixed, and in fact it was using Jiris patch.

However, the same problem came back while testing 2.6.36-rc4 and the
following -git's. /var/log/warn shows the same warning as mentioned in
the first mail in this thread:

 Sep 20 08:18:42 liesel apcupsd[5436]: apcupsd FATAL ERROR in linux-usb.c at line 609 
 Cannot find UPS device -- For a link to detailed USB trouble
 shooting information, please see <http://www.apcupsd.com/support.html>.
 Sep 20 08:18:42 liesel apcupsd[5436]: apcupsd error shutdown completed

No additional oops this time, only the warning, and my UPS is no longer
working.

Jiris patch obviously didn't made it into 2.6.36-rc4, and it doesn't
apply nay longer either.

Thanks,
Heinz.
