PC5750 Aircard

What is the correct desktop card readder required to use the PC5750 card?

Hello,
I purchased a Verizon PC5750 to use with my laptop. Wife wants to use it in her desktop, which does not have a card reader.
I found: Digigear EXP-USB USB to USB Mode ExpressCard Host Adapter for 3G AirCard AT&T Cingular Sprint Verizon Marlin Novatel EX720 V740 XU870
But I cannot tell if will work.
Thanks!
