#6335: Can't open CD drive file descriptor

----------------------------+-----------------------------------------------
Calling open() on /dev/disk/atapi/master/1/raw (on my laptop) currently
fails to return a valid file descriptor. This is causing CD Player to
report that a system does not have a CD drive installed.
Test code to reproduce the problem:
{{{
#include "CDAudioDevice.h"
#include <stdio.h>
#include <scsi.h>
int
main(void)
{
int devfd;
device_geometry g;
// This will need to be changed to suit the test system's
// hardware configuration.
BString name("/dev/disk/atapi/1/master/raw");
devfd = open(name.String(), O_RDONLY);
if (devfd < 0)
{
printf("Couldn't open device\n");
return -1;
}
if (ioctl(devfd, B_GET_GEOMETRY, &g, sizeof(g)) >= 0) {
if (g.device_type == B_CD)
printf("%s is a cd\n",name.String());
}
close(devfd);
return 0;
}
}}}
