Public bug reported:
# lsb_release -rd
Description: Ubuntu karmic (development branch)
Release: 9.10
I have connected a Polhemus Patriot tracking system to an USB port. I attempt
to connect to the device using:
/bin/sh -c 'modprobe usbserial vendor=0x0f44 product=0xef12'
This causes the kernel to log:

I had expected the kernel to create ttyUSB0 and ttyUSB1.
This works under Ubuntu 9.04 (after usbserial became a module).
