How do you know this isn't the fastest your device can handle? How about the host is it the bottleneck? Are there long periods of empty time on the bus if you look at it with an analyzer? Are you keeping the endpoints constantly full? What is the host doing to ensure the data is constantly flowing? In short, there's lots of questions here, you are going to have to be a lot more specific :) greg k-h -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
