No, you add it to the physical device node.
The usb mouse on the system I'm working on is here:
zweiblum kraxel $ ll /sys/class/input/ | grep usb2
lrwxrwxrwx. 1 root root 0 Dec 2 12:07 event7 ->
../../devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1:1.0/input/input7/event7/
lrwxrwxrwx. 1 root root 0 Dec 2 12:07 input7 ->
../../devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1:1.0/input/input7/
lrwxrwxrwx. 1 root root 0 Dec 2 12:07 mouse2 ->
../../devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1:1.0/input/input7/mouse2/
So "/sys/devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1:1.0" is the device
node of the physical device, and the input devices belonging to it are
in the "input" subdirectory.
If the mouse would be a usb IR receiver the IR attributes should go to
/sys/devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1:1.0 or maybe a 'ir'
subdirectory there.
