'Unknown port'from gphoto2, it either means that you typed the port argument (--port usb: ) incorrectly, or that gphoto2's USB support didn't make it into a compile somehow (if there's no mention of USB when doing gphoto2 --list-ports, above, this is your problem). Try the alternate installation steps for gphoto2 above, and give it another go.
gPhoto2 reported the error 'Could not find the requested device on the USB port'typically means that the USB camera isn't turned on, or plugged in.
