mounting USB card reader with SD card

[mr.popper]

I can't mount my SD flash card with a USB card reader. I typed "mount /dev/sda1 /mnt/usb", but I get "/dev/sda1 is not a valid block device". I tried this for sda1, sda2, sda3... but I get the same error every time. What should I do?

thanks,

with the card in try:

cat /proc/bus/usb/devices

That may tell you what device it is u need to mount.

This is what I get:

I don't understand any of it...

What device should I use?

[mr.popper]

fdisk -l showed a list of the devices... it was sdb1. It works now, thanks!

cool

WHY do i never remember to try fdisk -l first?!

I can't mount the card if my reader has multiple card slots. is there a solution for this?

[pablix]

It worked for me to change the kernel. as a 7in1-Reader seems to be treated as a scsi-device with more then on LUN, they have to be probed. After reboot I got required all devices.

# Some SCSI devices (e.g. CD jukebox) support multiple LUNs
CONFIG_SCSI_MULTI_LUN=y
