Portable USB SD Card Reader

hitest · 02-11-2007, 10:39 PM

I've got a portable USB SD card reader that I use for my Nikon digital camera, it plugs into a free USB port on my Slackware 11.0 box. I know it is Linux compliant as I've used it in Debian and Ubuntu.
It doesn't seem to show up when I plug it in to my Slack box.
Do I need to mount it at a shell prompt? I mount my cd rom drive with
#mount /mnt/cdrom

Any ideas what command I'd use to mount it and view my SD pictures?
Thank you for any and all replies:-)

try one or all of the following:

this will show all connected usb devices (as root)

Code:

lsusb

usually all drives available for mounting are listed in '/dev/disk/by-id' (with udev at least):

Code:

ls /dev/disk/by-id

it will be scsi so is listed here: (as root)

Code:

ls /proc/scsi/scsi

Which kernel are you using? And does the card reader have more than one slot?

I'm running the 2.6.18 kernel in slackware 11.0. The SD reader reads a variety of formats, nine types. But, I just use the SD slot for my camera.

Thanks, H_TexMeX_H:-)

I'll give your commands a shot:-)

Okay,

Thanks guys:-) Here is as far as I've got. I may need to add my reader to my fstab, maybe. I can see the reader at the shell prompt:-)

My PNY USB card reader didn't work in Slack 10.2. It does now with Slack 11...but only if my pc boots with the card reader pluged into my old Compaq laptop. When it boots it finds LUNS and finds my card reader. I then have to mount it....fdisk -l will show if it's recognized and mount /dev/sda1 /mnt/sda1 will mount sda1 (need to be root).

I haven't put it into /etc/fstab...not sure how it would boot if the reader wasn't there.

You need to run rescan-scsi-bus after plugging it in. This is because multi-card readers are not usually on the first lun or use more than one. The slot you want to use is probably /dev/sd(b,c,d) instead of /dev/sda.

Okay, thanks, gnashley:-) I'm leaving for work now I'll give it a try tonight:-) After I've run rescan-scsi-bus would I run this?

#mount /dev/sd(b,c,d)

Thanks, man!

After running rescan-scsi-bus, you should be able to mount on any existing mount-point, like /media/usb.
The basic form is:
mount /dev/sdc1 /media/usb

Note that the partition number may or may not be needed, depending on the sd card itself. Most will have a partition table and you should give the number, but there are some which have no partition table, where you'd mount the completet device without partition number.

Code:

root@slackbox:/home/hitest# ls /dev/disk/by-id
...
usb-Generic_STORAGE_DEVICE_136916

This is the one ... I should have said 'ls -l /dev/disk/by-id', cuz it's a symlink to the real name of the drive.

hitest · 02-12-2007, 07:39 PM

Okay, I've run a few commands:-) Here's as far as I've got.

Code:

it's sdf, so mount it ...

Code:

mount /dev/sdf /mnt/tmp

make sure there is a disk in there ... then you'll be able to write to /mnt/tmp all the files you want to go to disk. Oh, and read files from there too.
