After many exchanges via e-mail with el_supremo and numerous trials, the final CD burned today with USB2.0 enabled in the burned knoppix26 CD option of v3.4.

The hang-up in utilizing edits of the minirt26.gz file seemed to be the cloop.o version installed in my knoppix minirt26.gz file. After editing that exact minirt26.gz file from the knoppixLiveCD, the result was a good boot and USB2.0 enables file transfers at 17.9MB/sec.

The actual procedure is due to el_supremo because my use of his procedure did not produce the same result. Thus, I sent my file to him to edit and process and re-installed the result in a copied knoppixLiveCD file.

Mkisofs was then used to prepare the burn:

as ...su.....
mkisofs -pad -l -r -J -v -V "KNOPPIX" -no-emul-boot -boot-load-size 4 -boot-info-table -b boot/isolinux/isolinux.bin -c boot/isolinux/boot.cat -hide-rr-moved -o /root/knoppix.iso /root/CD. (spaces are important).

The destination for the .iso file is /root and the source file is /root/CD. The file size is in my computer is 687.9MB.

I am indebted to el_supremo for his support.
