    The usb-uart adapter (PL2303) will be visible as a usb device.

    Omega2+ 0.1.10-b160
    I simply connected / disconnected various USB-to-serial adapters to Omega's USB host port:

    Q (if USB webcam connected to Omega2's serial port)
    A NO

    Q (if USB webcam connected to Omega2's USB port)
    A Yes, will be recognized as a USB (webcam) imaging device. All subject to a suitable device driver's availability.

    Q if webcam's USB connecting to USB-serial dongle
    A NO (both are USB "end point" devices, end point device needs to talk to a USB "Host")
