Universal Adapter for XBOX360/PS3/PS2/PC USB issues with xbox 360

Hello there,

Does anyone own the Mayflash Universal Adapter for XBOX360/PS3/PS2/PC USB converter? I seem to have issues with it working on my xbox 360 when I am playing Super Street Fighter IV Arcade Edition using my modded Mayflash PS2/PS3/USB stick.

My layout for my Mayflash PS2/PS3/USB stick is as follows:

L1 [] ^ R1
L2 X O R2

My xbox 360 layout is

LB X Y RB
LT A B RT

There would be times that my LT (or L2) button would not work on my Mayflash PS2/PS3/USB stick. Anyone seem to have this problem using this converter?

Also, all my dipswitches on the back of the converter are switched to off.
