Re: no usb drive detected
Hate to ask, but HOW do you know no drive is detected? In earlier Ubuntu versions, plugging in a drive to a USB port popped open a window on the desktop. In 11.10, the default is NOT to do that.
So, if you're expecting to see a popup window, there won't be one.
Instead, it adds an icon to the Launcher.
So, next time look into the launcher and see if a new "drive" icon got added to the bottom of the set.
