tcgetattr is only applicable to serial ports. It looks like the
cyberpower driver has not been expanded to include their USB models

Can you use the serial port on the UPS?

The older hidups driver is going away soon; don't bother with it.

This driver has a debug dump for new USB/HID UPSes, but unfortunately
that feature isn't included in 2.0.3.
