To determine if Windows detects your expansion card, you need to check Device Manager to see if the card is listed under the appropriate heading or listed with an error. An example of an appropriate heading for a USB controller card is Universal Serial Bus controllers. The expansion card is listed in Device Manager as the name of the chipset. You can find the name of the chipset on the Technical Specifications tab for the product ID on https://www.startech.com/.
To open Device Manager, press the Windows key + R, type devmgmt.msc, and press Enter.
If you install a new CardBus or ExpressCard expansion card and Windows cannot detect the card, there are some quick tests that you can complete to identify the issue.
