Bug#716911: Seems the same problem here

[Alexander Prokoshev]

Hello.
It seems I have the same problem with Jessie here.

USB sticks detected successfully, but an Android phone (in mass storage
mode) not.
It had stopped working after upgrade from squeeze, I think.

I can help my laptop to show a USB volume's icon on my XFCE desktop by
executing "fdisk -l /dev/sdb" as root.



My dmesg's output:

Below is an output of "fdisk -l /dev/sdb" itself:
