Having spent a few hours across 2 days tracking this down, let me share my problem and the solution I found.

I wanted to use a sNES usb gamepad with XBMC on my Vista 32bit machine. On the XBMC.log file the name was "USB Gamepad" but using that name to set keymaps would lead to no change.

Using Regedit.exe I searched for the value "USB Gamepad" and changed each on to "ChangedGamepad#" where the # was a number higher for each one I found. Checking the log I found the new name (mine ended up being ChangedGamepad3) and added that to the keymap, and it worked.

Next problem: When using the dpad (it mapped as an x and y axis) each button push would give me 2-10 button presses, far faster than I could use. I downloaded AutoHotKey and use the following script:

PHP Code:

#Persistent  ; Keep this script running until the user explicitly exits it.

SetTimer, WatchAxis, 5
return

WatchAxis:
IfWinActive, XBMC
{
GetKeyState, JoyX, JoyX  ; Get position of X axis.
GetKeyState, JoyY, JoyY  ; Get position of Y axis.
KeyToHoldDownPrev = %KeyToHoldDown%  ; Prev now holds the key that was down before (if any).

if JoyX > 70
    KeyToHoldDown = Right
else if JoyX < 30
    KeyToHoldDown = Left
else if JoyY > 70
    KeyToHoldDown = Down
else if JoyY < 30
    KeyToHoldDown = Up
else
    KeyToHoldDown =

if KeyToHoldDown = %KeyToHoldDownPrev%  ; The correct key is already down (or no key is needed).
    return  ; Do nothing.

; Otherwise, release the previous key and press down the new key:
SetKeyDelay -1  ; Avoid delays between keystrokes.
if KeyToHoldDownPrev   ; There is a previous key to release.
    Send, {%KeyToHoldDownPrev% up}  ; Release it.
if KeyToHoldDown   ; There is a key to press down.
    Send, {%KeyToHoldDown% down}  ; Press it down.
return
} 


That allows me to map the dpad to the arrow keys of the keyboard, but only if XBMC is the active window. If an emulator is launched the gamepad is 100% perfect.
