Comment 117 for bug 843431

Serge, you are right, looks like the patch had the ID of the Hercules Dualpix Exchange wrong as you can see here:
http://kernel.opensuse.org/cgit/kernel/commit/?id=2394d67e446bf616a0885167d5f0d397bdacfdfc

The patch says USB_DEVICE(0x06f8, 0x0804) but it should instead say USB_DEVICE(0x06f8, 0x3005)
I suggest you email the 2 people you see in the Sign-Off line of the above patch, and ask them to fix it. This should be fixed in the official Linux Kernel rather Ubuntu.
