My failed attempts to make this work with apcupsd and nut have so
far been on two different physical Linux machines.

To try to prove fault I had to use Powerchute Serial Shutdown in a
Windows VM, but it doesn't misbehave there. I don't think I want to
go as far as installing Windows on a physical machine; I think PCSS
would still work there and so I'd learn nothing.

Trying different USB ports and/or a hub is worth a try I suppose!

It's what I fear.

I'd really like to hear if there's any other users of Back-UPS
BX1600MI or similar models out there. If there are no known
successful users of my model out there then I think this is a report
that it doesn't work and it's not just flaky USB on several of my
computers.

I guess in future I would have to hear from an apcupsd/nut user of a
specific model before I would be confident in buying it, especially
as APC customer service seemingly won't listen to any diagnostics
that don't come out of their hardware or Windows software.

Thanks,
Andy
