usb Usage type for HID not the same for windows.

(1/3) > >>

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?

Jan Axelson:
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."

Jan

ulao:
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.

Jan Axelson:
Can you post the complete report descriptor?

Jan

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

I will have to remove the FFB stuff.
