Switch Panel

A tiny little tool to enable the Logitech (Flight Sim) Switch Panel to work with any game, by intercepting the USB serial stream from it and translate into keystrokes.

For my own purposes specifically for use with:

• IL2
• Elite Dangerous

To enable this, when starting the app, it'll load in a config file containing the keystrokes it will output. By default it'll load in the config file 'keys0.json' but by setting an option on starting the app, any other keys file can be loaded. These files however must follow the format 'keys+number.json'. So by the command 'sPanel 4', it'll load in the file 'keys4.json'

This should allow existing owners of the Logitech Switch Panel to use it with newer games that Logitech do not provide plug-ins for - like for instance Flight Simulator 2020 from Microsoft.

Build

Will require libusb-1.0 or newer installed on the system. For Windows (or Mac) builds, please reference the guide from the gousb library README:

https://github.com/google/gousb

Linux should have this installed already, and if not is easily accesible from your distros package manager. Again reference the above link.

Binary

In Linux it will have to be run using sudo. In Windows, you'll probably have to agree to it being not signed and potentially even run as admin. I'll know when getting it compiled in Windows. Which as it turns out is a bit of a hurdle that I'll have to figure out.

Reason for these elevated priveliges is two-fold. For one, at least in Linux, without root/sudo, it won't grab the usb interface. Secondly, in the README for the keybd_event library it states it won't work unless running as root/sudo.

Windows may or may not be more forgiving.

USB info

From probing the USB devices (in linux) I fished out this info regarding the Logitech Switch Panel:

001.005 06a3:0d67 Pro Flight Switch Panel (Saitek PLC)
  Protocol: (Defined at Interface level)
  Configuration 1:
  --------------
  Interface 0 alternate setting 0 (available endpoints: [0x81(1,IN)])
    Human Interface Device (No Subclass) None
    ep #1 IN (address 0x81) interrupt - undefined usage [63 bytes]

and this:

T:  Bus=01 Lev=01 Prnt=01 Port=04 Cnt=02 Dev#=  6 Spd=12  MxCh= 0
D:  Ver= 2.00 Cls=00(>ifc ) Sub=00 Prot=00 MxPS=64 #Cfgs=  1

I:  If#= 0 Alt= 0 #EPs= 1 Cls=03(HID  ) Sub=00 Prot=00 Driver=usbhid

There should be also be an OUT endpoint, to control the landing gear status lights, but alas I've not found it.
