    The Minimorph doesn’t appear as a device on my host, when it is booted off my new image.

    You need to add the CDC Ethernet gadget module to your filesystem in buildroot.
    The main symptom of this problem is repeated ‘dwc_otg: USB RESET’ messages in the system log.
    Copy

    metag-linux/drivers/usb/gadget/g_cdc.ko 

    to

    buildroot/output/target/lib/modules/3.3.0/

    Then remake the ramdisk and kernel.
