Q:

Dell XPS l502x: multi card reader

I'm running Ubuntu 13.10 on my Dell XPS l502x. 
kernel: 3.11.0-15-generic
arch: x86_64

I'm not sure if this is a bug, so I'm trying to get a solution by asking here. 
If I don't boot my laptop with an SD card inserted, the SD-card-reader won't be
detected. 
I have to run
echo 1 > /sys/bus/pci/rescan

as root every time I want to use the card reader.  This problem is present since Ubuntu 11.10. 
Any ideas for a workaround on this? 
Maybe an init-script? 
If you need more information, just let me know. 
By the way: booting an older kernel doesn't help. 
Thank you :)

A:

I just found a Solution.  It was a Kernel Bug listed here
Whatever caused this Bug was fixed as of Kernel Version 3.12. 
I just installed the V3.13 Kernel from the Ubuntu Kernel PPA
The cardreader works fine now :-)
