Practically i modify the boot source and i set up sda2 like primary boot. On the usb is installed raspbian jessie, and once started i cannot using keyboard and mouse because the system not read this, but the light of keyboard and mouse are on. Can i fix this problem? Maybe edit something file? Thanks in advance
