tiny USB high res smooth scrolling

[VedantaHatwal]

trying to make high resolution scroll wheel I know it should be using the wheel 0x09, 0x38,
but i can get it to scroll but not smoothly i also know the resolution can be set with :
0x09, 0x48, // USAGE (Resolution Multiplier)
but i cannot get it to work

this is what i have so far it works just not high res or smooth
