Hi Marco,

Thanks for the patch. I'm switching this to the nut-upsuser list to get a wider audience for testing.

In case others run across this problem, could you please send the output of "upsc" for your UPS, and also the output of "lsusb -vvv -d 09ae:"? If you want to mask out part of the serial number, it is listed in "ups.serial" (and "device.serial") but the more information you can leave, the better we can identify any patterns.

If there is firmware version information in the USB descriptors, we might want to limit the scaling to certain versions.
