ttyUSB0 not appearing

Hi all,

Since an unplanned reboot yesterday, my USB<->RS232 adaptor is no longer appearing as /dev/ttyUSB0.

dmesg shows the following when it's plugged in:

usb 2-2.1: USB disconnect, address 4
usb 2-2.1: new full speed USB device using uhci_hcd and address 5
usb 2-2.1: configuration #1 chosen from 1 choice
input: MCT Corp. Serial Mouse Adaptor as /class/input/input9
input: USB HID v1.10 Mouse [MCT Corp. Serial Mouse Adaptor] on usb-0000:00:1f.4-2.1

Similarly, it's entry in /proc/bus/usb/devices appears to be:

T:  Bus=02 Lev=02 Prnt=02 Port=00 Cnt=01 Dev#=  5 Spd=12  MxCh= 0
D:  Ver= 1.10 Cls=00(>ifc ) Sub=00 Prot=00 MxPS=16 #Cfgs=  1
P:  Vendor=0711 ProdID=0231 Rev= 1.03
S:  Manufacturer=MCT Corp.
S:  Product=Serial Mouse Adaptor
C:* #Ifs= 1 Cfg#= 1 Atr=a0 MxPwr= 50mA
I:  If#= 0 Alt= 0 #EPs= 1 Cls=03(HID  ) Sub=01 Prot=02 Driver=usbhid
E:  Ad=81(I) Atr=03(Int.) MxPS=   8 Ivl=8ms

Sadly, I don't know what it used to appear as, whether it's always been treated as a "Serial Mouse Adaptor". In any case, I'm not using it for a mouse, I'm using it to talk to a temperature sensor module, and so I need to access it through ttyUSB0.

I haven't been able to find anything specific on google. Some posts relating to other distributions have pointed to it maybe appearing under /dev/tts/ but I don't have any such directory myself.

I'm using a fairly up to date install of Etch.

Many thanks in advance for any help,
