Hello, this sounds reminiscent of a discussion posted a couple of months ago; possibly the change was even proposed and integrated to NUT master branch - but can't say for sure, currently on phone not PC.

Beside that, there was a salicru subdriver merged some time ago, though maybe after the 2.8.0 release.

Hi, although my UPS brand is salicru it doesn't use salicru vendorid (2e66), it uses 06da.
So we can assume it's not a salicru but a rebranded ups.
The code 06da:ffff is assigned to 2 subdrivers: Phoenixtec/Liebert and MGE (only if vendor is "AEG" but mine is "PPC"). The problem is Phoenixtec/Liebert subdriver is very basic and doesn't support shutdown. Old version using MGE subdrivers was ok.
UPS shutdown is a very important feature, I need it to protect battery and to turn on my servers on again when power returns.
May be you can add same exception you do for 06da:ffff AEG vendor work if vendor is PPC. Or allow any way to select the subdriver to use.
Thanks

Selection of a subdriver in usbhid-ups (similar to how nutdrv_qx and blazer allow it) was logged some time ago, but so far nobody contributed the code... So I can hope it would eventually be there, maybe even I'd get some time to give it a shot, but no certainly present solution so far.

That all said, "PPC" is something I see often. Wondering if that is a generic chip identifier - so for some devices the Liebert mapping does work better... Or if there is some other field to (additionally) match for?..

I think #1968 is the PR/discussion I mentioned, which ports some abilities into Liebert mapping, including a shutdown.stop backend for an instant command.

See also #1967 and #1357.
