Hi
Thanks very much for the help. Your suggestion did work. The following line
modprobe usbserial vendor=0x0403 product=0xd738
did get us node in /dev when the device is plugged in, and dmesg gave us the following;
Apr 21 14:09:44 nors kernel: drivers/usb/serial/usb-serial.c: USB Serial support registered for Generic

and then...

Apr 21 14:13:12 nors kernel: drivers/usb/serial/ftdi_sio.c: v1.4.1:USB FTDI Serial Converters Driver
but unfortunately we ran into other problems. We still cannot communicate through the device, but that is most likely because our assumption that it was a straightforward usb->serial converter is not valid.
Thanks for the help!
