I can remove even mounted device. So it is not problem.

Problem is that I should do something after replace card by another card
of different size to be able mount new card.

camcontrol detach da0; camcontrol rescan all 
helps, but, it should be much better if it will be issued automatically.

Yes.

No. (If be more exact it does not depends on mount state).
USB device never disappear. Probably it reflect real state, I guess,
card-reader itself hardwired to USB hub inside notebook and never
disconnected.

Probably there is kind of disconnect notification on CAM level ?
