I got a duet ethernet that has never been used and cannot get it to connect to any of my computers.

It looks like this:

On two windows machines I get a unknown device (error 43).
My linux box has this in the syslog:

Aug 24 20:39:53 server kernel: [2407929.900833] usb 2-1.5: new full-speed USB device number 66 using ehci-pci

Aug 24 20:39:55 server kernel: [2407931.636247] hub 2-1:1.0: unable to enumerate USB device on port 5

I also tried reset and erase and a number of different cables.

Is there anything else I can try or is the device simply broken?

Thanks,
Jan
