Try: (some of this you have already done)

$ git clone git://kernel.ubuntu.com/ubuntu/ubuntu-vivid
$ cd ubuntu-vivid
$ vi debian.master/changelog
  . change '3.19.0-20.20' to '3.19.0-20.20~tkelly01'
    WARNING: After the '~' stick to numbers and alpha chars. Other chars my
break
             the build in odd ways.
$ echo 'CONFIG_USB_SERIAL=y' >> debian.master/config/config.common.ubuntu
$ echo 'CONFIG_USB_SERIAL_CONSOLE=y' >> debian.master/config/config.common.ubuntu
$ echo 'CONFIG_USB_SERIAL_PL2303=y' >> debian.master/config/config.common.ubuntu
$ fdr clean
$ fdr updateconfigs
$ fdr binary-headers binary-generic skipabi=true skipmodule=true
