I wanted to report some success with monitoring this UPS, a "Geek Squad"
brand GS-700U that I purchased earlier this year from Best Buy Canada.
Information about this... thing is very scarce so here is what I know:
The unit itself is probably made by Cyberpower. It has a 9-pin serial
port on the UPS, as well as a serial-USB adapter thing. I cracked open
the serial-USB adapter and printed on the PCB inside is "CYBERPOWER USB
1.7" which was a major tip-off.
I'm using nut 2.2.0 on a Pepper Pad 2 - which is a UMPC type device
based off of an Intel XScale CPU with a modified version of MontaVista
Linux Pro 3.1. (Linux kernel 18.104.22.168, gcc 3.4, *no* udev). The serial
port I used was actually a Belkin F5U103 USB to Serial port adapter. I
compiled nut against libusb 0.1.12.
Using the serial cable connected to a serial port, I was able to get NUT
monitoring it with the "genericups" driver with upstype=7 (CyberPower
Power99). At lease, the On-Line / On Battery status works with this
upstype setting - I haven't yet tested any of the other signals.
The serial-USB thing is identified as 0764:0005 on the USB bus, which is
supposed to be identified by usbhid-ups. However, when trying to use it
I got USBDEVFS control errors in the system logs, the same as this
I also tried the cyberpower driver and cpsups driver with no luck.
I have never tried to use the included Windows software that came with
the UPS, so I don't know if it even supports non-contact closure
features like voltages, load percentages, etc. I suppose I could try it
out in a VMWare virtual machine running XP and see what it does...
