I own 3 of the 6 Steinberg control surfaces CMC series

To run them, I added some entries in the (usb) quirk-table.

They are midi input and output of vendor ID Yahama and products as the following CMC-CH 0x1060 CMC-TP 0x1061 CMC-AI 0x1065

I wonder what the other three IDs might be ... ;-)

Where to notify that

Here.

For the patch, should I paste the lines in the last Linux Kernel version and create the patch?

Yes. See Documentation/SubmittingPatches for details, but a patch like this is really trivial.
