On Linux it does not take even a second, its instant.

Almost all multi-card readers targeted for consumers are USB type. I'm not 
sure whether there are non-USB based multi-card readers available.

to create necessary device is alright, but asking people to reboot the 
computer after plug in a card is unacceptable.
