Hi list,

is there a way to disable the mouse pointer for a specific HID on os x? I want to use an external usb mouse with [hidraw] without having it act as a mouse pointer in the user interface.

On Debian/GNU Linux I can achieve this with xinput in the following way:

List all X input devices xinput --list filter for numeric ID of "USB Optical Mouse" xinput --list | grep "USB Optical Mouse" | cut -d "=" -f 2 | cut -f 1 get the number for the "Device Enabled" parameter of that mouse xinput --list-props xinput --list | grep "USB Optical Mouse" | cut -d "=" -f 2 | cut -f 1 which in my case is 164. Then change its value to 0 or back to 1 xinput --set-prop xinput --list | grep "USB Optical Mouse" | cut -d "=" -f 2 | cut -f 1 164 0 xinput --set-prop xinput --list | grep "USB Optical Mouse" | cut -d "=" -f 2 | cut -f 1 164 1

It seems xinput is (was?) available via MacPorts. https://ports.macports.org/port/xinput/ I don't have an os x box to test this right now and am wondering if anyone has already done this.

Thanks for any hints! Peter
