# This VID/PID is owned by VOTI, a small dutch company. Usage is granted

# for 'internal lab use only' by VOTI under the conditions:
|
| 46 |
|
|
# - the gadgets in which you use those PIDs do not leave your desk
|
| 47 |
|
|
# - you won't complain to VOTI if you get in trouble with duplicate PIDs
|
| 48 |
|
|
# (for instance because someone else did not follow the previous rule).
