We are not sure X-55 is supported or not,
for it's not a tested one in our list.
Sorry for that.
And for more details of hardware support,
please visit:
http://www.reasnow.com/forum/index.php?topic=27.0As for the shifter support on X1 consoles,
there are 2 choices for you:
1. expert mode(beta version) support,
in this mode, all features(H shift, clutch, etc) are enabled except the forcefeed back,
but this expert mode support is still a testing version.
your wheel will work as a real wheel, which can be recognized by the console.
2. legacy mode support
shifter can only work as +/- shifter and force feedback is only a simulated one.
your wheel will work as a controller, and it will also be treated as a controller by the console.
For now, G920 is a good choice for X1 consoles.
