I've started my driver based on the edgeport code and so far it's looking quite promising, except for one thing… My device has descriptors based on the CDC-ACM scheme: in other words two interfaces for each channel, one with an interrupt IN endpoint for notifications, and another with a bulk IN and bulk OUT pair. Do you have any suggestions on how I can get the USB serial driver infrastructure to play nicely with my descriptors? I see that there is a hack in place to support PL2303 devices that have some similar problem, but I'd like to avoid that approach if at all possible. Thanks, Rob.
