How to install

  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:* d148221c-a849-4521-adab-75fe4eeaae9f_a88ef9d328c06688d2addaac6e1a501465c88326.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.
  4. Restart the computer and check that the device no longer shows a yellow warning sign in Device Manager.
