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
