    doubts about usb bootable keyboard



      can anyone tell me ??


      while booting when bios identyfies a usb bootable keyboard what exactly it does ( at firmware level)??


      and is it true that the keyboard communicates with host only using the control endpoint (as bios is still active and no OS is in pitcure) .when OS comes in picture the device can use Additional endpoints ( INTERRUPT IN to send the reports of the keys)..Please correct me if i am wrong...
