I need to be able to use the USB serial/JTAG interface while the Cmod S7 is powered externally using the VU pin. The datasheet says "To avoid risk of damage, any power source attached to the VU pin must be disconnected before a USB host is attached." This is a problem if you want to communicate with the module via USB while installed in a carrier card.
The USB circuit is missing from the schematic. Can diode D17 be removed to prevent the board from being powered via USB? If so, will the USB circuit still function? If not, what is Digilent's recommendations on using the USB port while the Cmod S7 is powered externally?

Hello,

Thanks,
