How to read data sent from a Joystick?

[$200]

Hi,

I am able to detect the joystick device and store the dev in a "usb_device":

struct usb_device *dev

I was told by the guy who did the firmware in the device that my program will need to read the following usage data sent by the device:

USAGE(x) - 0x30
USAGE(y) - 0x31
USAGE(Throttle) - 0xbb

Can anyone suggest how to do this?

Thanks a lot!
