HDMI video can work, but USB connection is not working.

What should I do? Please ensure you connect the PC to the "HDMI In" Ports and "USB Host" Port in the same group.

Please ensure you connect your USB devices to the right three blue USB 3.0 ports on the front panel of the KVM switch.

Try connecting the USB host cable to another USB port on your PC.

Try connecting the USB devices to the PC directly without using the KVM switch.

Then check if the USB connection works.

2.What can I do if there is no audio output from the 3.5mm audio port? Check your headset’ s 3.5mm audio jack.

It should have 3 pins instead of 4 pins to match the KVM switch’ s audio port.

Check if you have selected the headset as an audio output device on your PC.
