How do I use my YPG-635 Keyboard as a midi controller in PT-10?

[sonlightcity]

Hey everyone! I have a Yamaha Keyboard that I'm trying to use as a midi controller for the virtual instruments in Pro Tools 10. I downloaded the Yamaha USB-Midi driver, but it doesn't seem to work (although I'm probably just missing something). Does anyone have any idea on how I can get this to work? The driver was downloaded @ http://download.yamaha.com/usb_midi/

My keyboard model is YPG-635.

More information: I've hooked my keyboard up via MIDI to USB and installed the driver for the keyboard. I looked in Pro Tools to add it as a midi device, and it didn't even seem to recognize that it was plugged in.

Info on the computer I'm using:
Mac OS X, Version 10.6.8
2.66GHz Intel Core 2 Duo
4 GB 1067 MHz DDR3

Things I've already tried: I went into the Pro Tools Peripherals and Midi Setup and had no success. The keyboard didn't even show up as an option to add as a midi device.

Thanks in advance for any help!
