[Nut-upsuser] megatec_usb and "fry's" UPS

[Craig Falconer]

Gidday all - I've got a 1700VA dynamix UPS which is USB.

The previous model (with a serial port) worked wonderfully with megatec,
but this new one with USB is not working.

It feels like the kernel is not handing the USB device properly.
The web has not yeilded any useful info.

What can I do from here?
I'm not sure if its a kernel problem or a UPS config problem, but I'm 
hoping someone else has seen this before.
