Some NDIS USB drivers try to call URB funcs like URB_FUNCTION_VENDOR_xxx
or URB_FUNCTION_CLASS_xxx with HAL preemption lock that means it's
non-sleepable during USB requests though usb2_do_request() requires a
sleep so it needs to send queries to the default pipe without those
interfaces to avoid sleep.
