I got litle trouble after upgrading to karmic koala, since the upgrade I’ve had problems with usb-storage. After i plug the device, system not mount anything. Actually this issue happened in Jaunty, but finally working after i did litle trick, add this line into /etc/modules :
usb-storage option_zero_cd=2
But in Karmic, it doesn’t work as i expected . This problem happened because device id 05c6:1000 is not initialized correctly and stopped with result :
[ 144.565583] usb 2-1: configuration #1 chosen from 1 choice
[ 144.576078] usb-storage: probe of 2-1:1.0 failed with error -5
So i guess this happened in all devices which share these IDs (used by a Qualcomm chipset for storage device)
I wish i can find a solution immediately, Damn, i’ts so annoying if i remove first memory card from my mobile phone, then connected through Card Reader just for data exchange
