Using grub as bootloader and hdc=ide-scsi hdd=ide-scsi where hdc is DVD and hdd is DVD writer , when logged in as normal user the o/p from cdrecord -scanbus only shows my writer , yet when logged in as root and perform the same command the o/p from the scan shows both devices , dvd reader device 0 and writer device 1 !!! . Why can't the normal user scan the bus??
Thanx in advance
