* For USB Device operation; insert jumpers in position 1-2 in JP17/JP18/JP19. GPIO28 controls USB
* connect functionality and 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.
* For USB 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

/* USB1
* When USB channel #1 is used as USB 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
*
* When USB channel #1 is used as USB 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.
