Liebert GXT4 not Working on Synology (RackStation 815+)

[Nam00r4]

I tried to connect my Liebert GXT4 via USB to my RS815+.

The USB is also recognized

  |__usb2          1d6b:0002:0310 09  2.00  480MBit/s 0mA 1IF  (Linux 3.10.108 etxhci_hcd-170202 Etron xHCI Host Controller 0000:04:00.0) hub
  |__2-1         10af:0000:0000 00  1.10   12MBit/s 0mA 1IF  (Vertiv Co. Liebert GXT4 2034101151AFE13)

But the service wont start since it tells that the modell is not supported.
If seen for others, that it worked with this USV

:; sudo upsdrvctl start
Network UPS Tools - UPS driver controller DSM7-1-1-42930-workplus-version2-repack-42930-220712

This Liebert device (10af:0000) is not (or perhaps not yet) supported
by usbhid-ups. Please make sure you have an up-to-date version of NUT. If
this does not fix the problem, try running the driver with the
'-x productid=0000' option. Please report your results to the NUT user's
mailing list <nut-upsuser@lists.alioth.debian.org>.

No matching HID UPS found
Driver failed to start (exit status=1)

UPS -x not found in ups.conf

• ups.conf

driver = usbhid-ups
port = auto
productid = 0000

Sadly, their firmware bastardizes actual versions of the software they embed, but by other versions seen here (e.g. usbhid-ups 0.41) that is NUT v2.7.4 or near that. Released over 10 years ago now. See if you can get them to use a newer release?

sudo upsdrvctl start -x productid=0000

The upsdrvctl wrapper manages starting of driver configurations, and does not take many further parameters. What you tried here would have fit with running the driver directly, e.g. usbhid-ups -a myups -x opt=arg...

The ups.conf example looks wrong at face value, in reality does it have the specific driver configuration section starting like [myups] before driver=... and other lines?

[Nam00r4]

the ups.conf was not available, I created the file.
only the upssyno.conf was there - with configuration of UPS over LAN
Can some1 pls give me an example, how the content of the whole file should look like?

[jimklimov]

This one is almost okay:

[myups]
driver = usbhid-ups
port = auto
productid = 0000
vendorid = 10af

But generally there are many programs and config files involved in setting up NUT servers and clients. For a full syntax example and explanation, see https://github.com/networkupstools/nut/tree/v2.7.4/conf
