You mean the generic usb-serial drivr works for this device?  Nice.

Short answer, you can't automatically load the generic usb-serial driver
for any devices.  Use the modules /etc/ files to do it for you at boot
time.

Long answer, write a very tiny usb-serial driver that uses these
vendor/product device ids.  Then it will be automatically loaded
properly.  Someone has done this for another type of device in the
latest -mm kernel if you want an example of this.

Yeah, that's a kernel bug, sorry, haven't gotten around to fixing it
yet...  Nothing udev can do there to help you :(
