USB2.0 Card reader Manual

Inspect the kernel logs. If there isn't anything that could be USB related,
likely causes are use of the wrong driver (UHCI when you needed OHCI or
OHCI when you needed UHCI), not physically installing the hardware,
a BIOS configuration that disables USB or stuffing up the configuration or
installation of the kernel.
Use the mount command: mount -t usbdevfs none /proc/bus/usb. Note that the
'none' keyword is arbitrary.
If you do not want to have to mount the filesystem each time you reboot the
system,you can add the following to /etc/fstab after the /proc entry.none .
/proc/bus/usb usbdevfs defaults 0 0
*********************************************************************
5. Edit /etc/fstab
The exact syntax depends on the Card Reader. The best way is to make suitable
entries in /etc/fstab. The suitable entries for Card Reader would be:
/dev/sda1 /mnt/sm auto noauto,user 0 0
/dev/sdb1 /mnt/cf auto noauto,user 0 0
/dev/sdc1 /mnt/mmc auto noauto,user 0 0
/dev/sdd1 /mnt/ms auto noauto,user 0 0
6 . To check if all flash card has been attached, type the following line at console
mode cat /proc/scsi/scsi
Linux will response as follows if the flash cards are attached successfully
[root@localhost root]# cat /proc/scsi/scsi
