Slight correction: "port" can be set to anything for the USB-based NUT drivers (it is ignored in the driver, but other parts of NUT need some non-empty value for it), so the statement "the first serial console was being used to communicate with the UPS" does not follow.

Does the output from "upsc mustek" look reasonable?

Thanks for the report,
