USB keys do not automount, cannot be manually mounted

[Reuben Firmin]

Binary package hint: mountmanager

dmesg reports that my USB key has been attached:

[ 1617.001891] scsi 14:0:0:0: Direct-Access Kingston DataTraveler 2.0 1.00 PQ: 0 ANSI: 2

However, it is not automounted by nautilus/gnome. Further, when I try to manually mount it, I get strange behaviour:

sudo mount /dev/sdk2 /tmp/usb
mount: special device /dev/sdk2 does not exist

And indeed, it does not exist:

ls /dev/sd*
/dev/sda /dev/sdb /dev/sdb2 /dev/sdc /dev/sdc2 /dev/sdc4 /dev/sdd1 /dev/sde1 /dev/sdg /dev/sdi
/dev/sda1 /dev/sdb1 /dev/sdb3 /dev/sdc1 /dev/sdc3 /dev/sdd /dev/sde /dev/sdf /dev/sdh /dev/sdj

lsusb does not see it.

usb-devices _does_ see it:

This is reproducible with my other two USB keys, which have different manufacturers. All three mounted fine in karmic.

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

S: Manufacturer=SanDisk
S: Product=U3 Cruzer Micro
S: SerialNumber=2204620CD800141A
C: #Ifs= 1 Cfg#= 1 Atr=80 MxPwr=200mA
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.
