I have a Samsung Galaxy S, using the default firmware (version 2.2). It is configured to select "Mass Storage" when plugged in via micro USB.
When I plug the phone into the cable, I receive the "Click here to connect via USB" button.
However, when I click it, the phone thinks for a bit and then tells me that it's connected; yet Windows makes no mention of it and the drives are not accessible from the computer. It has worked in the past, but has apparently decided I am no longer worthy or something.
I have rebooted both the phone and the computer with no change in behaviour.
What am I doing wrong? Is there something obvious I've missed?
