I use a KVM to switch between computers. The KVM allows for a single keyboard and mouse to control up to 4 computers. This KVM has 4 inputs:
1) USB Keyboard connection
2) USB Mouse connection
3) Generic USB connection
4) Another generic USB connection
When selecting a computer, all 4 of those inputs get connected to the selected computer.
The keyboard connector seems to be different from the generic USB inputs in one respect: It intercepts the keystrokes from the keyboard and looks for the sequence CTRL + CTRL + 1/2/3 or 4. Likewise it also looks for ScollLock + ScrollLock + 1/2/3 or 4. For either of those keyboard sequences, it causes the KVM to switch to the selected system. For example, if I press CTRL + CTRL + 2, the KVM will switch to computer #2. This has always worked fine, however, I finally just replaced my ten year old mechanical keyboard with a new one and I cannot get the keyboard to work on that keyboard port of the KVM. This keyboard is one of those that supports a very high polling rate of up to 8,000 Hz whereas a standard keyboard is only 125 Hz. I initially thought that this might be the problem, but my new keyboard allows me to change the polling rate, so I dropped it down to the standard 125 Hz and that still did not work.
I have found that if I connect the keyboard to one of the generic USB ports, then the keyboard works just fine, however I lose the ability to switch to another computer using the hotkey sequence on the keyboard.
My KVM does have a physical button on it that I can use to switch between computers, but the KVM is out of reach from where I sit. I could relocate the KVM to my desk, but that would require that I purchase longer USB and HDMI cables to reach each of my computers.
Is this an issue for which anyone knows of any sort of corrective action or setting?
The keyboard in question is a Corsair K70 Max RGB Magnetic-Mechanical keyboard.
The switch is an AIMOS AM-KVM401.
