Query: Was not detected by Verizon V740 ExpressCard on two Dell laptops

Attempted to use this adaptor on two Dell laptops, one fairly old (2-3yrs) and one new (<1 yr), with a Verizon V740 ExpressCard, which I believe is USB-based, and neither PC could detect the card while using this adaptor. Perhaps bad luck? Who knows?
