Greetings,
What's going on here?
I just purchased a Rosewill powered USB hub. I tested output and it is @ 5.1 V.
When I plug into my Arduino Duemilanovo TX and Rx plus PWR LED are lit.
But, if I plug into my USB on laptop Tx and Rx are not lit.
Thanks in advance.

Doesn't sound like comm's are being started when the hub is used.

Have you tested the USB Hub with other USB devices to ensure that it is working?
