+ * @next_tx_frame:	The next frame this pipe is allowed to transmit on
+ * @flags:		State flags for this pipe
+ * @device_speed:	Speed of device connected to this pipe
+ * @transfer_type:	Type of transaction supported by this pipe
+ * @transfer_dir:	IN or OUT. Ignored for Control
+ * @multi_count:	Max packet in a row for the device
+ * @max_packet:		The device's maximum packet size in bytes
+ * @device_addr:	USB device address at other end of pipe
+ * @endpoint_num:	USB endpoint number at other end of pipe
+ * @hub_device_addr:	Hub address this device is connected to
+ * @hub_port:		Hub port this device is connected to
+ * @pid_toggle:		This toggles between 0/1 on every packet send to track
