Yes, please. This will change later when Pat Mochels devicefs kicks in,
but for the time being, it'd be very useful.

I'm not sure, I may have proposed it. I'm not sure of the outcome

the devices - there is no other way to differentiate between two
identical USB mice.

Do you think it could be added?
