 # ezCoo managed multiport KVM switch
 
+!!! warning
+    While we provide this document for your convenience, this is a third-party hardware device in the same path as a PiKVM. Therefore, you may need to experiment (trial and error) to get it to work how you like. In the case of the U3P (hot key version), it may or may not work as expected.

-The ezCoo managed switch can be controlled by PiKVM to allow it to connect to multiple hosts. A typical scenario is a single PiKVM device which can control and switch between multiple hosts or servers using the ezCoo switch. UI elements can be added to the [GPIO dropdown](gpio.md) to allow switching between hosts from the PiKVM webpage. The instructions here were tested with the ~~[ezCoo SW41HA HDMI 4x1 switch](https://www.easycoolav.com/products/hdmi20-switch-4x1-with-usb20-kvm-4-port-usbsupport-4k60hz-444-and-hdr-audio-breakout)~~ [ezCoo EZ-SW41HA-KVMU3L 4x1 switch](https://www.easycoolav.com/products/hdmi20-switch-4x1-with-usb30-kvm-3-port-usbsupport-4k60hz-444-and-hdr-audio-breakout-36) OR [eccoo EZ-SW41HA-KVMU3P 4x1 switch](https://www.amazon.com/gp/product/B09ZKZK7ZB). Both older USB2.0 and newer USB3.0 variants are supported. The following was testing on a Raspberry Pi 4 but should also work on the Pi 2 and 3. This document was createdy using the contributions from multiple users in our [Discord](https://discord.gg/bpmXfz5) and the author appreciates their efforts.

 !!! info
     While most images of the switch do not show the sides, there is a Micro USB port on the side of the ezCoo switch. This is the management port, which is controlled via COM port on the ezCoo KVM. When plugged into the Raspberry Pi, it appears as `/dev/ttyUSB0`.
