Issue Description
When trying to use a KVM switch with TrueNAS or Debian Linux, you may encounter issues where the keyboard and mouse do not work properly. This can be frustrating, especially when trying to manage multiple servers or workstations.
Possible Solutions
Solution 1: Update Firmware
The first solution is to update the firmware of your KVM switch. This can often resolve compatibility issues with newer operating systems like TrueNAS and Debian Linux.
To update the firmware, follow the manufacturer's instructions. For CKlau KVM switches, you can download the latest firmware from their website and use the provided software to update.
Solution 2: Change KVM Switch Port
If updating the firmware does not resolve the issue, try changing the KVM switch port that the keyboard and mouse are connected to. Sometimes, the ports can become faulty, and switching to a different one can solve the problem.
Solution 3: Change Keyboard and Mouse USB Ports
If the issue persists, try changing the USB ports on the KVM switch and the keyboard and mouse. Sometimes, a USB port can become faulty, causing the keyboard and mouse to not work properly.
Solution 4: Change KVM Switch Settings
Some KVM switches have settings that can affect keyboard and mouse behavior. Try changing these settings to see if it resolves the issue.
Solution 5: Use a USB Hub
If none of the above solutions work, try using a USB hub to connect the keyboard and mouse to the KVM switch. This can sometimes resolve compatibility issues.
