I am really comuter illiterate, but here goes.
I have a verizon PC 5750 aircard,and I would like to be able to use it on my desktop computer. Is there a way to do that? An adapter of some sort?

Here is one of the more expensive adapters: Cyberguys.com - Byte Brothers PCD-X/U142-E USB to CardBus Adapter for 3g Modem PCMCIA Card

There are two standards. I think this is the right one.
