Hi,
Here's a patch for the usb-serial drivers against 2.3.99-pre7-2 that
fixes the devfs support (if anyone still has problems with it, please
let me know), updates the documentation for the drivers, adds the
ability for the firmware tool to work properly with dos line ending
firmware files, and fixes the copyright notice in the source code files.
thanks,
greg k-h
