The drivers below, and directions are based on Windows 10/11… There is more than one way to skin a cat in Windows; this is the manual way, as I find the update driver via Device Manager does not always find the most current driver.
-
Disconnect the DigiRig from the USB cable (If you have Device Manager open, the Silicon Labs with the exclamation mark notation under Other Devices, should disappear);
-
From your web browser, download this file link previously listed by @Constrainted, into your Download (or directory of your choice, but I’ll use Download in this example) Directory:
https://www.silabs.com/documents/public/software/CP210x_Universal_Windows_Driver.zip
-
Open your Download directory either from your web browser menu, or Windows Explorer and locate the CP210x_Universal_Windows_Driver.zip file;
-
Right click on the CP210x_Universal_Windows_Driver.zip file, and select Extract All;
-
Leave the suggested directory location in the pop-up, which will be the same directory that you’re already in, and check Show Extracted Files When Complete if it’s not already checked, then click Extract;
-
You should see 6 files (UpdateParameters, CP210x_Universal_Windows_Driver_Release (You should read this file as an FYI plus install details), 2 of silabser, SLAB_Licence_Agreement_VCP_Windows, and UpdateParam), and 4 directories (x64, x86, arm, arm64);
-
Right click silabser.inf (it’ll be the one with the gear in the icon);
-
Select Install from the pop-up;
-
You will see a security warning, asking if you want to open this file - Select Open;
-
If you are not logged into your Administrator Account (you should normally be in a User Account as it’s harder to wreck things by accident, plus better for security of the computer), a pop-up will ask for your Administrator PIN - enter it;
After a moment you should get a pop-up that says, The Operation was Completed Successfully; then
- Plug the USB back into the DigiRig and the driver should install, and you’ll see the Silicon Labs CP210x USB to UART Bridge (COM X) show up under Ports (COM & LPT) in the Device Manager, no longer under Other Devices.
If that doesn’t work let me know.
