Want to program my own USB Driver for older Controller... help anyone??

Hey folks.
Not sure if this is where to post this, but, I have a very old (2006?) CME UF5 Midi/USB keyboard controller.
The CME company stopped their drivers for it with Windows XP, nothing later.
It does have a MIDI Output, which I am using at the moment, but some of the controls (i.e. Transport buttons) don't spit-out the MIDI port.
My wife put the damper on my getting a new controller, which I know is the best solution. So, being an older programmer, I was wondering if I could in fact program my very own USB Driver for this keyboard!
Any thoughts or avenues to go from you guys??
TIA!
