APC used to do that. The first UPS I bought which was a 1500VA beast
had one as did IIRC a similar 1000VA one I got via eBay for my son to
use. I've no idea why APC used to do this but the last one I bought had
a standard USB socket, type B I think. If anyone needs a type A -> RJ45
cable let me know, I believe I have a couple of them somewhere.

Off topic but in my very limited experience smaller units seem to have
better longevity than the 1000/1500VA ones. I also have a second hand
Back-UPS CS 350 obtained via eBay in September 2004 for £20 - bargain!
- solely for protecting my DECT base phone, digital answering machine
and Virgin cable modem. All are still working perfectly whilst two
answering machines previously failed, possibly due to line surges.
Meanwhile both of the higher power units have failed. One of them kept
tripping in for no good reason several times each hour, the other one,
something inside it went BANG one day which was a little disturbing but
my server survived and ran on just filtered mains for a couple of days
until I received the new unit.

Perhaps I should treat the CS-350 to a new battery. It continues to sit
in the darkness under my desk, gathering dust while continuing to do
its job.

BTW both of these UPS are connected to a Belkin Gold unit, mainly
because it has a coax cable/satellite TV surge protector which the UPS
units do not.
