 With the appended patch the ubt initializes for me, even if usb2/ehci
 is used by the host controller.
 The "16" happens to be the "wMaxPacketSize" in the endpoint descriptor;
 I'm not sure yet whether it should be the driver's duty to check that
 or the framework should care.
 I'm also not sure whether the builtin Dell hub is somehow limited or
 the translation problems are to be expected under the timing/size conditions
 imposed by the ubt driver.
 
 best regards
 Matthias
