TS-7970 USB Device Port
From embeddedTS Manuals
The USB type B device port is connected to the onboard Silabs for USB to serial console, or to the CPU's #USB OTG. The USB functionality is picked from the "CON EN" jumper.
|Note:||Previous to REV C TS-7970, the USB device port can prevent the CPU from booting up if "CON_EN" is removed, and USB is plugged in before CPU power is connected. As a workaround on earlier revs you can cut the red wire from your USB cable.|
