Hi Stuart,
Thank you for the link. It does seem what I am looking for. Are you aware
of any similar standard created for a serial device? I have a working CDC
usb setup, which is why I am asking. If required, will switch to HID though.

Many of the HID-based UPS use the Power Device Class, docs are at
