Thomas, thanks for your clarification. I will rule out the check on wireless devices by using 'dev->speed' in v2, but not only because WUSB HC supports building a packet from discontinous buffers, but also below: - max packet size of wireless device's endpoint might be changed runtime - wireless devices can't be used in common USB(1.1/2.0/3.0) bus.
