I'm located in Oregon. But that is exactly what I purchased this modem to do. Unplugged the comcast modem, replaced it with this modem, called comcast gave a representative the MAC address from the label on the modem, and returned the old one. Now no more $7 lease fee. Hope this helps.

The USB is actially an output similar to the ethernet output. I think some laptops allow you to connect to the modem via USB instead of ethernet port. In that case, you can use this USB port.

As of today's(Oct 24th) local office visit, for Comcast "extended" basic 80(+/-) TV channels and Internet bundle(my choice), this version 2.0 modem is good to go! Best guess is there are several modems depending on your application. It appears to be a matter of how you will use it. It also appears to be more complicated than it needs to be; as it changes from region to region. Best regards!

Visit Comcast's DOCSIS Devices page for list of approved modems.
The only DOCSIS 3.0 Motorola modems listed are: SB 6120; SB 6121 and SBG 6580(modem gateway). Those available at W-M are higher cost than the SB 5101U.
Regret this answer is so dated - just getting around to my own "research".

No, the USB port on the back of the modem is a type-B connector and the connector on the Magic Jack controller is a type-A. They are made this way to prohibit backwards communications.

This unit is a "cable" modem, and you need a cable service provider in order for it to work.

If you don't want to own a cable modem, you can rent a unit from your service provider, for a nominal monthly charge.
