Im new in linux, just installed Ubuntu 11.10 in a Dell Inspiron 9400, everything works fine with the exception of the SD card reader, everytime I insert a card the computer doesnt do anything, its like the SD card reader is not there.

I did a $lspci and it shows the next drivers

03:01.0 FireWire (IEEE 1394): Ricoh Co Ltd R5C832 IEEE 1394 Controller

03:01.1 SD Host controller: Ricoh Co Ltd R5C822 SD/SDIO/MMC/MS/MSPro Host Adapter (rev 19)

03:01.2 System peripheral: Ricoh Co Ltd R5C592 Memory Stick Bus Host Adapter (rev 0a)

03:01.3 System peripheral: Ricoh Co Ltd xD-Picture Card Controller (rev 05)

Everytime I insert a memory card, dmesg shows the next

d status 0x600b00

and more of the same but with different sector number Im using Kernel 3.0.0-12-generic

By the way, when I was installing it and ubuntu asks about installation (If I want to install it along with windows or delete something or change the partitions of the HDD) if I go to the window to change the partition of the disc, linux detects the SD Card (if there's one inserted course).

Any help with this it would be appreciated -sorry for my english

Thank you
