To solve this problem, I worked with an engineering firm to create a custom circuit board that splits the Pi's USB-C port into two. The first port accepts USB power, so you can still deliver a full 3 Amps to the Pi. The second accepts USB data out, so the Pi can still impersonate a USB keyboard.

Install the TinyPilot software Unlimited Video Walls – create multiple video walls with up to 12 x 12 (144 displays max.) in each layout Ultra High Definition (UHD) video quality – up to 3840 x 2160 @ 60Hz (4:2:0), 3840 x 2160 @ 30 Hz (4:4:4); 24-bit color depthWant an pre-made, high-quality KVM over IP device? The TinyPilot Voyager is a pre-assembled, plug 'n play solution with a smaller form factor and higher quality video capture than the HDMI to USB dongle. Parts list Some types of active KVM switches do not emit signals that exactly match the physical keyboard, monitor, and mouse, which can result in unwanted behavior of the controlled machines. For example, the user of a multimedia keyboard connected to a KVM switch may find that the keyboard's multimedia keys have no effect on the controlled computers.
