No, I just didn't know which ones were FLOSS-friendly when I was at the 
computer store. :-)  I picked the Belkins because I liked their case-design
hack of putting the plugs on the top surface, which is more accessible 
than the uusual rear-of-the-unit placement.

In any case, the device more or less seems to work with the megatec_usb 
driver.  Or it did, anyway -- with latest trunk it's not finding the USB 
device.

Serial-over-USB transport layer for Megatec protocol driver [megatec_usb]

Megatec protocol UPS not detected.
Driver failed to start (exit status=1)

System log has many entries that say:

May 24 12:18:37 snark kernel: [136718.407859] usb 3-2: usbfs: process 26061 (megatec_usb) did not claim interface 0 before use

How do I troubleshoot this?

By the way, see where it says "2.1.0 (916M)" there?  Thst's my patch to include
SVN revision in the version string operating.  As soon as I actually get
nut working again, I'll ship it to you.

Maybe.  Are you going to fix things so that nut is inoked and automatically
configures itself when a user plugs in a USB UPS?  Because if not, I have some
ideas and even code to contribute towards that.  I made it happpen in gpsd.
