1. Make sure this is the right driver: open Device Manager (right-click Start → Device Manager), right-click your device → Properties → Details → Hardware Ids, and compare the value with the supported IDs below. See how to find a hardware ID.
2. The driver comes as a .cab package. Open Command Prompt as administrator in the download folder and unpack it:
   mkdir C:\Drivers\pkg
expand -F:* 631de993-7b44-48cc-ae25-637ac98e8c31_c10cfd57acadd4e303f322d0eae4e2f24f2948d9.cab C:\Drivers\pkg
   (Alternatively, double-click the .cab file, select all files and copy them to a folder.)
3. Install the driver: pnputil /add-driver C:\Drivers\pkg\*.inf /install — or in Device Manager right-click the device → Update driver → Browse my computer for drivers → select C:\Drivers\pkg.
