Usually you'll want to use a USB debug cable in this case. That's different from a USB<->serial adapter such as you would use to connect a USB host to a serial peripheral such as a modem. It provides a serial-like connection to the host, using a simple driver implemented in SourceLevelDebugPkg/Library/DebugCommunicationLibUsb or SourceLevelDebugPkg/Library/DebugCommunicationLibUsb3. Usually only one serial port on a platform is available for use as a USB debug port. You'll need to consult your board schematic and chipset documentation to see which one. I haven't used one myself (my targets have serial ports), but you should be able to find more info online. -- Brian J.
