OK, so it's a wireless network card...nothing to do with USB
Did you take a look in Device Manager to see if there are indications of problems with it? It should be reflected under the Network Adapters category and...tell us if you see any yellow or red markings (indicating a problem with the device).
Start/Run...type devmgmt.msc, hit OK.
What info is reflected in Device Manager (maker, model)?
Manufacturer and model of computer system?
And...why did you think there's a connection between this card and USB? Are you having problems with USB devices?
