usb-storage detected but drive not assigned

Hi group,

I can't mount a usb music stick with a fat fs because
a drive letter eg /dev/sda has not been assigned.
Here's dmesg:

<snip>
usb 1-2: new full speed USB device using uhci_hcd and
address 2
usb 1-2: configuration #1 chosen from 1 choice
Initializing USB Mass Storage driver...
scsi0 : SCSI emulation for USB Mass Storage devices

scanning

usb 1-2: new full speed USB device using uhci_hcd and
address 3

scanning
scsi 1:0:0:0: Direct-Access     USB      FLASH DISK
V2.0  2120 PQ: 0 ANSI: 2
usb-storage: device scan complete

And $cat /proc/partitions only lists the two
hard-drives.

The device works OK in another gentoo unit with the
same kernel config and modules as far as usb is
concerned.

I did #mknod /dev/sda b 8 0 and tried to mount it
there and then tried /dev/sda1 but got "/dev/sda not a
valid block device" and "/dev/sda1 does not
exist"
respectively.

Yes, the fat and vfat modules are inserted.

Did you include modules for scsi disks?  I think it's
sd_mod.
