The value for the port string is ignored, though it must be present - you can change that to "auto" or "dummy" if you want. (See the usbhid-ups man page for details if you need to distinguish between multiple UPSes on a single system: http://networkupstools.org/docs/man/usbhid-ups.html#_extra_arguments )

You can also add "productid=0000" here, and try running the driver and upsd. (Either use the usbhid-ups command line below, and run "sudo /sbin/upsd", or kill the driver and run "sudo service nut-server restart"

Added that productid:

   https://github.com/networkupstools/nut/tree/Liebert_GXT4

If you had to manually change permissions, you could add the following to /lib/udev/rules.d/62-nut-usbups.rules for the next reboot:

#  Liebert GXT4  - usbhid-ups
ATTR{idVendor}=="10af", ATTR{idProduct}=="0004", MODE="664", GROUP="nut"

Most of the numbers look good, but it is unclear why some values (such as Voltage and ConfigVoltage) are not being reported correctly:

   0.230714	Report[get]: (5 bytes) => 05 51 00 48 00
   0.230729	Path: UPS.PowerSummary.Voltage, Type: Feature, ReportID: 0x05, Offset: 0, Size: 16, Value: 1
   0.230738	Report[buf]: (5 bytes) => 05 51 00 48 00
   0.230750	Path: UPS.PowerSummary.ConfigVoltage, Type: Feature, ReportID: 0x05, Offset: 16, Size: 16, Value: 0

(This should not affect the OB/LB status, though I would advise testing just the same.)

After starting the driver and upsd, what does "upsc ups" return? If you can also include "upsrw ups" and "upscmd -l ups" output, we can update the DDL.
