When you say "bootable USB drive" (in your original mail), is it a CDROM 
connected via USB or is it a USB stick? I assume it is a USB stick, but 
it isn't clear.

How did you make that bootable USB drive? Did you just copy the ISO image 
to the USB stick with the dd command (or something similar)? That 
wouldn't work because the kernel knows that a USB stick is something 
different than a CDROM. The original ISO image expects to be started from 
a CD, not from a hard disk or USB stick. As a part of the pendrivelinux 
article the isolinux.cfg file is replaced by a modified version which 
doesn't look for a CDROM but uses whatever devive it is booted from. I 
suppose, you can just download the .zip file mentioned in the article and 
replace the isolinux.cfg file on your USB stick with the one in the .zip
