USB mass storage mapping problem
Hello, does anyone know what I might be missing with trying to get a valid
device for an usb SD card reader?
Thanks for any input,
Steve
sg_scan -i and sg_map show the following:
bash-2.03# sg_scan -i
/dev/sg0: scsi0 channel=0 id=0 lun=0 [em] type=5
LITE-ON LTR-48246S SS06 [wide=0 sync=0 cmdq=0 sftre=0 pq=0x0]
/dev/sg1: scsi0 channel=0 id=1 lun=0 [em] type=5
CD-ROM Drive/F5A B1.4 [wide=0 sync=0 cmdq=0 sftre=0 pq=0x0]
/dev/sg2: scsi1 channel=0 id=0 lun=0 [em] type=0
Generic USB SD Reader 2.00 [wide=0 sync=0 cmdq=0 sftre=0 pq=0x0]
bash-2.03# sg_map
/dev/sg0 /dev/scd0
/dev/sg1 /dev/scd1
/dev/sg2
sg2 is not mountable:
bash-2.03# mount -t vfat /dev/sg2 /camera
mount: /dev/sg2 is not a block device
The cd is mountable under two devices:
bash-2.03# mount -t iso9660 /dev/scd1 /cdrom
mount: block device /dev/scd1 is write-protected, mounting read-only
bash-2.03# mount -t iso9660 /dev/sr1 /cdrom
mount: block device /dev/sr1 is write-protected, mounting read-only
