* In very rare cases, some motherboards contain a buggy BIOS that does not understand the keyboard of the **v2** platform (bellow). The reason for this is that the BIOS doesn't fully implement the USB HID stack for composite devices correctly. Meanwhile, Mass Storage Drive can be detected. For this case, we suggest using the Arduino HID from the **v0** platform with **v2**. Thus the Pi-KVM will be connected by two USB cables to the motherboard: one of them will be responsible for the keyboard and mouse, the other for everything else. See [here](pages/arduino_hid.md).

* A similar problem can be observed on devices with UEFI: the keyboard works fine, but the mouse does not work. This situation occurs when UEFI does not support absolute mouse mode, which prefers to use Pi-KVM. To solve this problem, [you can enable relative mouse mode](pages/mouse.md).
Our future [v3 platform](#the-future-v3-platform-work-in-progress) will contain an optional HID module for such cases, so you won't have to build anything yourself.
