USB auto detection in Linux
 

Hi, Can any one please let me know how USB device auto detection happening.
Is device auto detection is a S/W(OS) logic or H/W(mechanical) logic or both?
What OS internals in Linux identifies device presence or removed from system?

thanks in advance.

Hopefully this will provide a starting point where you can get a basic idea and then be able to search for more information about how the linux USB subsystem works.
