I've read some (but not all) of this thread.  AFAICT, you want to prepare
an Ubuntu-type USB installation disk, and you tried to use the Debian 
installation manual, as described above, but it didn't quite work.

I would recommend having a look at the corresponding section in Ubuntu's
installation guide.  It's very similar to Debian's but I remember noticing
some small differences.  Maybe try
https://help.ubuntu.com/11.04/installation-guide/amd64/boot-usb-files.html

Around 4 or 5 years ago, I was doing an Ubuntu installation with a USB 
stick.  The guide looked very much like Debian's so I assumed they were
the same and tried to do it like Debian, but it didn't work.  (I think 
the difference I experienced was that in Debian the "easy" method required
one to copy an iso after copying the image to the USB, whereas in Ubuntu, 
one just copied the image and that was it (no iso to copy).  I'm not sure,
though.)
