USB Ubuntu Still Being a Pain.

I have extracted all the initrd.gz images I can come across and fixed up the references to them in isolinux.cfg and syslinux.cfg but I still have the same problem. It would be nice if it told me which file in the archive was causing the problem. The problem seems to no longer exist when I have the computer up and running and I try and extract the files from the .img archives that I have created but during the boot up it insists that there is still an "invalid compressed format (err=2)".

I'm actually quite surprised that switching the names around in the config files and extracting the img archives from the gz ones worked to the point of actualy saying "loading initrd.img" not "initrd.gz". I actualy kind of suspected that it would cause the thing to go haywire when it tried to decompress the img as a gz but obviously it can tell the difference.

Another thing that happens when I boot Ubuntu up now off the usb is that it does it very slowly, much slower than of a CD. I have mentioned that before but now because the initrd.img is extraced it takes 3 times as long. I had a look at the file sizes and concluded the major bottleneck was reading the data off the USB. As a img the file is 3 times the size it is when it is a gz. I was wondering how I might be able to somehow put drivers in some archive is enable some option that would mean that it would take advantage of the 2.0 port instead of reading data of the USB in 1.1 mode.
