usb Usage type for HID not the same for windows.

[ulao]

In windows I can use this list and its correct.

Generic Desktop
0x00 Undefined
0x01 Pointer
0x02 Mouse
0x03 Reserved
0x04 Joystick
0x05 Game Pad
0x06 Keyboard
0x07 Keypad
0x08 Multi-axis Controller

My devise is a  Game Pad  as it uses force feed back so I must use 0x05. Now in linux 0x05 shows up as a mouse? Does anyone have the list for linux ubuntu (debian). If the list is in fact not the same, how is a developer going to deal with that?

These values are from the USB-IF's HID Usage tables document.

I don't know what you mean by "in linux 0x05 shows up as a mouse."

Just simply that. If I do the following.

0x05,0x01, // Usage Page Generic Desktop
0x09,0x05, // Usage gamepad
0xA1,0x01, // Collection Application

In windows I get a gamepad. In linux ubuntu (debian) I get a mouse. Even if I move the x/y analogs on my stick it will move the mouse. Looking in the device folder its a mouse.

On a side note:If I change 0x05 to 0x04 it now shows as a joystick and works that way. Though , this is no good because its now a joystick not a game pad, so windows wont use the FFB.

I'm told this implementation may not be the same for linux.

Can you post the complete report descriptor?

OMG, you crazzy! LOL .. ok you asked for it.


urr,ok I cant

I will have to remove the FFB stuff.

You could start with a basic report descriptor like the one here:

http://ww1.microchip.com/downloads/en/AppNotes/91054c.pdf

or model your descriptor on one from a working gamepad.

If it works under Windows, check Device Manager to see if it's using additional drivers.

Yeah I did all that basic testing and it still just as I described. So based on your response, you would say this is not the case? In that the implementation should be the same x-plat form? So it must be a kernel issue ( bug ).

It only uses the one HID gamepad driver.

[Jan Axelson]

Do your descriptors match those for a gamepad that works under Linux?

Jan

[ulao]

hmm you lost me a bit there? Unless you mean do my descriptors match another games pads descriptors . I will have to see if I have another usb "gamePad" type around.

[ulao]

Well I found another gamepad but I can not see in windows what it is? DM calls it a game controller but that is a lot of good? So here is usbView. This device does not show the descriptor, any idea what it is?

but that does not tell my what the 0x09 usage is.
