That sounds right, but here we have a situation where a keyboard and a mouse will overwhelm the bandwidth, but a Class-10/UDH-1 SSD will not. I really don't type that fast. I should be able to tell the driver that I don't type several billion words per minute or move my hand faster than sound, yes? OK, I'm being a little facetious, but it does seem to me that if a HID device is being used, there should be a way to downgrade the claim that it is a "full speed USB device". In any case, "better to" question, in my case, it's "no". I do not like having three keyboards stacked one on top of another. So I really need some way to fix this. :( -- 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
