How do I check if my ExtremeCap UAC is ready or not?
Go to Device Manager on your PC and make sure AVerMedia ExtremeCap UAC is listed under Imaging devices and Sound, video and game controllers.
*In some rare cases, your ExtremeCap UAC might be detected as a question mark (?) or a USB audio device. If that happens, right-click the device name and select Uninstall, and then reconnect the USB cable.
Note: after Windows 10-1709 update BU110 Extreme Cap UVC will be listed in Device Manager under “Cameras” instead of Imaging devices.
