Joystick support

[GoogleCodeExporter]

I've been trying to add joystick support to the driver using the following 
report descriptor (see bottom). This is replacing the report descriptors given 
in vmulti.h.

The driver builds and install correctly but when I try and view "Properties" 
for the device under "Game Controllers" I get an error reading that "The game 
controller is not connected properly".

Do you have any advice or is there an example of this working?

Many thanks.

I have added this joystick descriptor (with the small modification of having a 
report id) to the vmulti source repo along with a test in testvmulti.exe.

It seems to work ok (you can see the joystick properties changing in the game 
controller control panel applet.

That's strange, I actually tried this. There must have been a small difference 
some where - I will investigate. Thank you.

On closer inspection it seems that the problem is that my driver is not being 
reinstalled after I make a change. What is your workflow?

I'm running (in an x86 checked build environment)

> buildme.bat
> cd bin
> devcon remove hid\vmulti
> devcon install vmulti.inf hid\vmulti

The first installation (after clone) was fine (and I got a confirmation dialog) 
but every subsequent build returns "Drivers installed successfully".

But the actual controller profile doesn't update to reflect my changes (I think 
this was the problem originally!).

Am I doing anything obviously wrong?

Thank you!

"devcon remove" just deletes the device stack (doesnt actually remove the 
driver from the driver store)

you could try "DevCon Dp_delete" or "DevCon Update" but what I have been doing 
is just delete the vmulti device node from device manager and select the 
"delect driver files" checkbox (which I think removes the driver from the 
driver store)

How would I go about adding Z rotation reporting to the joystick? This is 
crucial to be able to use it in actual games.
