Memory Card reader is not working in Ubuntu

Could you report result of command:
   sudo lsusb
I presume your card reader uses an internal USB link.

Can you give the full make / model of the netbook

Thanks

After running "sudo lsusb" it gives me the following result:

Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 001 Device 002: ID 174f:1122 Syntek
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

The model of my Netbook is "Compaq Mini CQ10-500 EEE PC". In Windows it used "Realtek Card Reader Driver" for the internal memory card.

The model of my Netbook is "Compaq Mini CQ10-500 EEE PC". In Windows it used "Realtek Card Reader Driver" for the internal memory card.

"Bus 001 Device 002: ID 174f:1122 Syntek" is the webcam.
So card reader is not connected via USB (or there is a hardware issue).
Could you paste in http://paste.ubuntu.com/ the result of command:
   sudo lshw

Could you put a card inside card reader, and report result of command:
   sudo fdisk -l
where "-l" is lower case "-L".

Dear Delance,
Thanks for your suggestion and guidance. I've pasted the thread in http://paste.ubuntu.com But perhaps I couldn't publish it properly. The link of the post is http://paste.ubuntu.com/550099/plain.

I've run the command "sudo fdisk -l" after putting a card card in the card reader and got the following result:

Disk /dev/sda: 160.0 GB, 160041885696 bytes
255 heads, 63 sectors/track, 19457 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x000841d0

   Device Boot Start End Blocks Id System
/dev/sda1 * 1 19076 153219072 83 Linux
/dev/sda2 19076 19458 3068929 5 Extended
/dev/sda5 19076 19458 3068928 82 Linux swap / Solaris

Your card is not seen by system.
The results of "lswh" make me think that card reader is not properly managed by Linux kernel.
I can't do more.

Actually I've got the same problem over here with the very same netbook, but I've found the solution as well (even though reading this thread I almost gave up actually…☺).
I did it actually on Arch Linux, but it shouldn't make much difference.
 You have to download the Linux driver sources from over here (the Ralink website):
http://218.210.127.131/downloads/downloadsView.aspx?Langid=1&PNid=15&PFid=25&Level=4&Conn=3&DownTypeID=3&GetDown=false
Unpack, go to that place in a terminal, then
1) make
2) make install
3) depmod
4) reboot your computer
(as copied from the README file from the archive)
Actually I didn't reboot my computer, however I issued the command “sudo insmod rts_pstor.ko” to test it out. It works like charm.

For this to work, you need to have the header files for your kernel installed.
