And illegal as per the GPL. Stay away from that driver as far as you can, and if you are able, stay away from that chip. There are many others just as good out there, that cost the same. > The solution seems to be migrating to the cp2101 kernel module.

Can't you use something else? If not, then try it out and see how well the cp2101 driver works for you, like you would do for any other driver :) thanks, greg k-h ------------------------------------------------------- This SF.Net email is sponsored by xPML, a groundbreaking scripting language that extends applications into web and mobile media.
