I tested 4 flashes and 1 USB HDD - you can read my test report (https://docs.google.com/spreadsheet/ccc?key=0Ao5e713Ig9g_dHJBalI2b09TQ2ZNOHJOQnhFbEVXaXc). The conclusion is very bad: I tested Ubuntu 12.04 LTS, Ubuntu 13.04, Fedora 18, OpenSuse 12.3. All they can't remove power from USB drives like it was in GNOME 2 and previous versions of GNOME 3.
