I didn't know that USB could get to 4.8Gb/s :) For USB 2.0 speeds, the tty layer should be just fine, right? Put a microcontroller doing data acquision on the other side of it, and I would be amazed if it could keep up with the data rate. But hey, Ron knows his system better than us, perhaps it can do this, and if so, then you might want to look into something else. thanks, 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
