Hey -
    just wanted everyone to know that the problem turned out to be that
I was plugging in this modem to the front USB ports of my Dell PowerEdge
2850 server -- and when I plugged the modem into one of the back ports,
it was recognized immediately!  hopefully this will help anyone else
having a similar problem (cos it drove me nuts!).
