TS-8950-49xx USB OTG
The USB OTG port can be used either as console, or access to the CPU's USB OTG. When the "CONSOLE" jumper is off, this header can make the board appear is a serial, ethernet, midi, or some other device depending on how the kernel is configured. See #USB OTG for more information.
With the Console jumper on, this port connects to the CPU console using a CP210X driver.
