Another gentlemen posted his X-52 mappings, so I'm posting my X-55.

I didn't bother to make a throttle mapping, since the options are pretty binary and I'm still relying on the keyboard for various unfrequently used buttons, so hitting backspace every now and then isn't an issue.

Note: The X-55 uses weird "A, B, C, etc" identifications for some buttons.

Button
A = Cycle Weapon Config ("X")
B = Cycle Weapon Systems ("W")
C = Target Ahead\Roll (JOY2)
D = Match Speed
Pinky = Toggle Beam

H1: Target/Energy Stuff
---
H1Up = Adjust laser recharge
H1Right = Select Previous Target
H1Down = Adjust Beam Recharge
H1Left = Cycle Target Components

H2: Shield Stuff
---
H2Up = Adjust Shield Config
H2Right = Transfer Laser Energy to Shields
H2Down = Adjust Shield Recharge
H2Left = Transfer Shield Energy to Lasers
