Arkmicro Technologies Inc. ARK3116 Serial

[Darran.Lee]

Hi
I am trying to use an Arkmicro Technologies ARK3116 USB to serial cable to communicate with my C118. I have compiled Osmocom-bb successfully on my Debian Squeeze laptop.
When I try to run the osmocon utility I get an error "Cannot open serial device /dev/ttyUSB0"
My dmesg etc output is:
[  769.752182] usb 5-2: new full speed USB device using uhci_hcd and address 5
[  769.908979] usb 5-2: New USB device found, idVendor=6547, idProduct=0232

So I am assuming the drivers are installed correctly but if I run osmocon I get:
./osmocon -p /dev/ttyUSB0 -m c123xor ../../target/firmware/board/compal_e88/loader.compalram.bin 
Cannot open serial device /dev/ttyUSB0
My Question is, does anyone here have any experience with the Arkmicro Technologies ARK3116 Serial cable?
Is there something I have missed?
Thanks
