Support for APC SMC2200BI-BR by usbhid-ups

[fernandolcx]

This is a new 2017 model targeted to brazilian market.
It does have a USB port and a RJ50 serial port.
Since I don't have a 940-0625A (RJ50 to DB9) cable, I'm passing through the USB port to a Ubuntu 18.04 VM on VMware Workstation, running NUT v2.7.4 and using the usbhid-ups driver.

But.. some important readings are missing:

fernando@ubuntu:~$ upsc worldbyte@localhost

ups.status: OL CHRG
ups.timer.reboot: -1
ups.timer.shutdown: -1
ups.vendorid: 051d

I was hoping to see somethig like input.voltage or ups.load .

Also:

fernando@ubuntu:~$ upscmd -l worldbyte@localhost
Instant commands supported on UPS [worldbyte]:

beeper.disable - Disable the UPS beeper
beeper.enable - Enable the UPS beeper
beeper.mute - Temporarily mute the UPS beeper
beeper.off - Obsolete (use beeper.disable or beeper.mute)
beeper.on - Obsolete (use beeper.enable)
load.off - Turn off the load immediately
load.off.delay - Turn off the load with a delay (seconds)
shutdown.reboot - Shut down the load briefly while rebooting the UPS
shutdown.stop - Stop a shutdown in progress

Through PowerChute on a Windows VM, I'm able to:

• Make all readings correctly
• Test beeper
• Run Battery Callibration
• Run Self-test

Any thoughts?

EDIT:
Here is the result of
sudo /lib/nut/usbhid-ups -DD -a ups -x vendorid=051d* 2>&1

Missing values are likely due to NUT's lack of Modbus support: #139
