Hm, I don't know the ehci stuff, so I can't comment on that, but as far as the idea goes, I really like it. I get a few questions a year about using Linux to run USB compliance tests, especially from embedded people who do not run any other operating system on their machines. So anything you can do to help this happen would be greatly appreciated. thanks, greg k-h ------------------------------------------------------- This SF.Net email is sponsored by xPML, a groundbreaking scripting language that extends applications into web and mobile media.
