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 below), 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).
❗WARNING:exclamation: - AiMOS has a back powering issue that makes the Pi behave differently, there is a work around [here](https://github.com/pikvm/pikvm/blob/master/pages/Community_FAQ.md#misc-stuff)
❗WARNING:exclamation: - If you choose AiMOS, be aware that it has a back powering issue that you need to use work arounds for. Limitations are are listed below

Limitations:
- HDMI backpower needs to be mitigated - Please see Solution 2 or use a [Cheap 13$ HDMI splitter will work](https://www.amazon.com/dp/B07DQBY5TX)
- MSD work around is needed as it will not work OOB
- **Solutions**
- Solution 1: RPi4 OTG needs to be in the KB port for mouse and KB funtionality, ZeroW is required and needs to be connected to the HUB port for HK switching and MSD functionality - ✔**KNOWN WORKING**✔
- See [here](https://github.com/pikvm/pikvm/issues/128)
