Mount USB Disk on Debian Etch that doesn't have a module node?


Hey guys, this is my first post. I'm a relative beginner with linux, but I am pretty good with the Google so I've been doing a decent bit of poking around.

I have a machine that has an integrated USB flash drive somewhere in it that I can not seem to mount. The OS knows it is there, as I can see it in the dmesg output, but the actual "node" in /dev doesn't actually exist. I'm baffled. Will you help me figure this out?

Here's what I came up with so far. The disk is attached to the USB bus, used as a SCSI block device. In dmesg, it is referred to at one point as sdf, as well as under /sys/class/scsi_device. When I go check /dev, /dev/sdf does not exist!:

Code:
cat /proc/bus/usb/devices
T:  Bus=02 Lev=01 Prnt=01 Port=00 Cnt=01 Dev#=  2 Spd=480 MxCh= 0
D:  Ver= 2.00 Cls=00(>ifc ) Sub=00 Prot=00 MxPS=64 #Cfgs=  1

E:  Ad=02(O) Atr=02(Bulk) MxPS= 512 Ivl=31875us

I have no idea what else to look at or where to begin. I would greatly appreciate any tips or tricks you might have, as I am flat out stumped!

Does it show up on fdisk -l (as root of course)? And in your "mount" output, what is the directory /USB? Is this a homebuilt machine, or a model number you could give us?

No, it does not show up on fdisk -l.

The box is a linux appliance from Netgear. I was toying with the idea of implementing ZFS on it and was trying to figure out how I might go about it.
