Firstly, bugs on the Ubuntu installer belong on the debian-installer source package in Ubuntu, not on the debian-installer upstream project.
Secondly, as of Ubuntu 8.10, unetbootin should be changed to pass cdrom-detect/try-usb=true as a kernel command line option if it wants the installer to try to probe USB devices. (Sorry, this won't work with 8.04.) See bug 234185.
