 ALso Pi-KVM can be connected to a multi-port HDMI/USB switch and the switch's buttons can be connected via optocouplers to [the Pi's GPIO to switch channels](gpio.md).
 
 If your KVM switches channels using keyboard shortcuts, there is a chance that it will not be able to work with OTG (v2 platform, see bellow), since it does not fully implement the USB stack. In this case, you will have to [use an Arduino board](arduino_hid.md) to emulate the keyboard & mouse (Pi-KVM supports this configuration)

+* ![#f03c15](https://placehold.it/15/f03c15/000000?text=+) - Everything is working as expected. There may be some subtleties.
+* ![#ffaa00](https://placehold.it/15/ffaa00/000000?text=+) - The switch does not work with OTG (**v2**) and requires an [Arduino HID](arduino_hid.md) or soldering [GPIO](gpio.md) to switch channels or something like that.
+* ![#f03c15](https://placehold.it/15/f03c15/000000?text=+) - The keyboard or mouse does not work at all, the switch loses the image, etc.
