Not everything is hardware. :)

No problem, how about this:
  /sys/class/input/
  |-- input0
  |   |-- event0
  |   |   `-- dev
  |   `-- mouse0
  |   |   `-- dev
  |-- input1
  |   |-- event1
  |   |   `-- dev
  |   `-- ts0
  |   |   `-- dev
  |-- mice
  |   `-- dev
  `-- interfaces
      |-- event0 ->·../input0/event0
      |-- event1 ->·../input1/event1
      |-- mouse0 ->·../input0/mouse0
      |-- mice -> ../mice
      `-- ts0 -> ../input1/ts0
