It looks as if the MK-149 is simply midi. I'm assuming you have a midi interface that you plugged the 149 into? In that case, you need drivers for your interface, not the keyboard.
The mk-149 doesn't have USB, either you are mistaken about how you are connecting the computer, or you have a different(newer) keyboard. Either way, your driver questions are answered in your similar thread in the KVR forum.

Everytime i connect my mk-149 i get a pop up on my status bar informing me that the USB is not recognised , but i can use my flash drive , external hard drive via the USB and will get no error message. But i get the same error message everytime i use the midi keyboard , so i actually think it is the driver for the keyboard.
