Comment (by pulkomandy):

 No, same error.

 I noticed that the device is connected to USB only when I insert a card,
 and removed when I remove it. Seems like the card detection switch powers
 on the USB logic. So, I expect a "media change" event immediately on first
 access to the device, but retrying should get past that, and we shoundn't
 get any other "media change" event, as removing the card will cut power to
 the device before it can send it anyway.

 I have seen other devices sending media change on first connection as
 well. Maybe we should ignore that only the first time ?
