* USB0 Device operation:
* - Insert jumpers in position 1-2 in JP17/JP18/JP19.
* - GPIO28 controls USB connect functionality
* - LED32 lights when the USB Device is connected. SJ4 has pads 1-2 shorted by default.
* - LED33 is controlled by GPIO27 and signals USB-up state. GPIO54 is used for VBUS
* sensing.
*
* USB0 Host operation:
* - insert jumpers in position 2-3 in JP17/JP18/JP19.
* - USB Host power is controlled via distribution switch U20 (found in schematic page 11).
* - Signal GPIO26 is active low and enables +5V on VBUS2.
* - LED35 light whenever +5V is present on VBUS2.
* - GPIO55 is connected to status feedback from the distribution switch.
* - GPIO54 is used for VBUS sensing. 15Kohm pull-down resistors are always active
*
* Note:
* - Insert jumpers in position 2-3 in JP17/JP18/JP19
* - Insert jumpers in JP31 (OTG)

*
* For USB1 Device:
* - a 1.5Kohm pull-up resistor is needed on the USB DP data signal. There are two methods to create this.
* JP15 is inserted and the pull-up resistor is always enabled. Alternatively, the pull-up resistor is activated
* inside the USB OTG chip (U31), and this has to be done via the I2C interface of GPIO52/GPIO53. In the latter case,
* JP15 shall not be inserted.
* - J19 is the connector to use when USB Device is used. Normally it should be a USB-B connector for
* creating a USB Device interface, but the mini-AB connector can also be used in this case. The status
* of VBUS can be read via U31.
* - JP16 shall not be inserted.
*
* For USB1 Host:
* - 15Kohm pull-down resistors are needed on the USB data signals. These are activated inside the USB OTG chip (U31),
* and this has to be done via the I2C interface of GPIO52/GPIO53.
* - J20 is the connector to use when USB Host is used. In order to provide +5V to the external USB
* device connected to this connector (J20), channel A of U20 must be enabled. It is enabled by default
* since SJ5 is normally connected between pin 1-2.
* - LED34 lights green when +5V is available on J20.
* - JP15 shall not be inserted. JP16 has no effect
