How to install the non-free firmware for Keyspan USB <-> serial converters

KeyspanDriverHowto:: This Howto documents how to get a Keyspan USB-to-serial converter working with Ubuntu. Most of these devices require firmware to be downloaded to the device each time you connect it to your USB bus. The problem is that this firmware is distributed with a license too restrictive to allow Ubuntu to redistribute it.

Use a kernel.org kernel

Compile your own kernel from kernel.org source. See the KernelCompileHowto for more information on how to do this.

Patch the ubuntu kernel

This is a bit sneakier. For now, I will say that you need to download the kernel.org kernel, and copy keyspan* from drivers/usb/serial to drivers/usb/serial in the unpacked ubuntu kernel tree. Also, copy the relevant bits from Kconfig in the upstream drivers/usb/serial directory into Kconfig in the same directory under the Unbutu source tree.

Then compile it, using the KernelCompileHowto as a guide.

This is a very rushed stab at an explanation, mainly so I can get the page out there, and tidy it up later. Sorry for the mess. :(
