Where could I explore this further? Are these sequences specific to the device?

My current setup includes two Dell monitors (U2415 with 2x HDMI "MHL" inputs and built in USB-3 hubs.) I'm using these with a Linux X86_64 desktop. I also use Logi vertical mouse and ATK (A.JAZZ) keyboard, both on Bluetooth and both also have dongles.

I would dearly love to use the keyboard/monitor/mouse on a Raspberry Pi 5 (BT and two micro-HDMI ports) with a pure S/W based solution rather than spending $$$ for a H/W KVM switch.

Thanks!

Edit: WRT messy code - no judgement, no shaming here. BTDT.

This works for me:

  import hid

  VID = 0x046D
  HID = 0xB023 # 0xB35B

  if __name__ == "__main__":
      h = hid.device()
      h.open(VID, HID)
      h.set_nonblocking(1)

      # this works for keyboard
      # h.write([0x11, 0x01, 0x09, 0x1F, 0x01] + [0] * 15)

      # this works for mouse
      h.write([0x11, 0x01, 0x0A, 0x1E, 0x01] + [0] * 15)
      h.close()
