Users report success with drivers for USB serial bridges when installing Windows 11.
So ive recently purchased a radar detector, and trying to get it updated. through some searching found that their update tool doesn't install windows 11 drivers. Managed to go to find the correct drivers and get them downloaded, but im having issues still. This unit uses a micro usb to attach to the pc. its got a helpful txt file with some intstructions on it, but it doesn't help that when going into the regedit the regestries aren't there, and the paramaters in the inf file are uncommented. ive tried installing the .inf file and says oem com port 194 installed on 0 devices. heres and excerpt out of the txt file for install The VCP driver package contains the following files and directories: - silabser.inf -- Driver information file - SLAB_License_Agreement_VCP_Windows.txt -- Software License - CP210x_Universal_Windows_Driver_ReleaseNotes.txt -- this file Additional files needed by installer - silabser.cat - x64/silabser.sys - x86/silabser.sys INSTALLING ---------- The VCP driver is automatically installed by Windows Update for CP210x with alternate PID values of 0xEA63, 0xEA7A, and 0xEA7B.
