[Nut-upsuser] Bug#671444: LiebertPSP

Tim Gould tgould at reverb.com.au

I upgraded to trunk (3652) - it worked, but again with the seemingly spurious RB during DISCHRG.

-DDD output attached. RB turns up just before battery.charge.low is reached (around 1551 sec), at the same time LB turns up too. 

Once a slave client (on the same UPS) shuts down battery.charge goes back up above battery.charge.low, so LB goes away, but RB stays.

I didn't have upsmon running on this host so it ran until the battery was depleted rather than shutting down.

Hope this helps, thanks, Tim.

>>> In this message, Alastair cited Pier's patch which changes the subdriver for 10af:0001 from belkin-hid to liebert-hid. Due to the way that we match the HID usages, we probably could have put the scale fixes in the liebert-hid subdriver instead, but I agree that belkin-hid is probably the right mapping under the hood.
