Hmm... Well, I'm not at his computer right now to be certain, but it's a westell Wirespeed B90-210015-04, as I recall. The Router... Netgear 54 Mbps Wireless Router Model WGR614.
I still think it has something to do with his computer, though. The Verizon software "detected" that he should use the USB connection, but he definitely has an Ethernet port. I think the problem lies somewhere in there.
Thank you for the replies.
