hi
I am using ubuntu 8.04
i have samsung2120 with 2GB micro sd card connected inside.
in settings it is configured to be used as 'mass storage'.
When i connect mobile via data cable in windows xp then as desired I get accessible drive just like USB stick plugged in.
In ubuntu 8.04 following happens
Code:
#lsusb
