Description: Ubuntu precise (development branch)
Release: 12.04

When rhythmbox is not launched, & when I plug in my usb Sansa Express (2GB) from Sandisk along with a 2GB microSD, nautilus opens both partitions. Here dmesg when doing this:

When I launch rhythmbox I can see, under Devices:

2.0 GB Filesystem
Media Player

Selecting the first displays the tracks.
Selecting the second (i.e; Media Player), the first (i.e; 2.0 GB Filesystem) disappears from "Devices" & I get the following dmesg:
[ 2728.456046] usb 2-1: reset high-speed USB device number 7 using ehci_hcd
after afew seconds the tracks of this memory are displayed.
