I have problems with my usb cardreader in Linux Ubuntu 12.04 . I think the device is detected by the operating system, but not shown in category devices and therefore not available.

I have checked the following commands:

cardreader not connected:

1 Answer 1

The Card Reader does work on Ubuntu 12.04 but the OS doesn't seem to find the card when it is inserted. It appears you have 2 options in the short term :

A. Reboot with the sdcard in the slot ;-)

B. Do a pci re-scan (execute the following as root)

sudo su -l

echo 1 > /sys/bus/pci/rescan

The bug with the workaround is listed here

OR:

On the terminal type sudo blkid before inserting the device, this will print all the block devices currently on your system. Now insert the device and type sudo blkid again. Now you will see that the new device has been added (either as /dev/sdbx or as /dev/sdcx or as /dev/sddx, where x>=1).

Now go to the terminal again and type sudo mount /dev/sdxx /dir/to/be/mounted/ where xx are the last 2 letters of the device that you just detected.

Now, the files will be accessible at the /dir/to/be/mounted. Also make note that you have use sudo to copy files into the directory.

And before you remove the device, unmount it using sudo umount /dev/sdxx

@G Koe : I tried all solution methods, but unfortunately nothing did solve the problem. When I tried solution 3: sudo blkid did not show a new device after I inserted the cardreader including micro sd card. thx anyway for the help :). –  user304670 Mar 11 at 21:21
