Comment 1 for bug 553481

Actually I spoke too soon. My sandisk key mounts as a CDROM drive!

From dmesg:

[ 2393.506405] usb-storage: device found at 13

Not sure from the above whether sdk* or sr1 is the device, but regardless it doesn't exist if I ls /dev.

usb-devices sees it as:

T: Bus=01 Lev=01 Prnt=01 Port=06 Cnt=03 Dev#= 13 Spd=480 MxCh= 0
D: Ver= 2.00 Cls=00(>ifc ) Sub=00 Prot=00 MxPS=64 #Cfgs= 1

I: If#= 0 Alt= 0 #EPs= 2 Cls=08(stor.) Sub=06 Prot=50 Driver=usb-storage

Again, lsusb does not see it.

My pico usb key has the same behaviour as the kingston.
