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.

HTH,
