Nut upsuser - Nov 2008 - Is usbhid-ups compatible with APC Back-UPS ES 550VA and 700VA devices?

Hello,

I would like to know if usbhid-ups is the right and best driver for
these devices.

I'm confused. The data list mentions only the "APC Back-UPS
ES/CyberFort
350" as compatible and does not give more information about the full
APC/MGE family devices. Also, I'm not sure that an APC Back-UPS ES 550VA
or its equivalent 700VA is the same device as the described Back-UPS ES.
For instance, APC Back-UPS ES 400VA doesn't  even have an usb port to
communicate with the pc. It becomes hard to know if all such devices on
the market are nut compatible.

Thanks for your help.
