First of all, did you check the md5 of the ISO you downloaded?

Grab a checker, https://help.ubuntu.com/community/HowToMD5SUM#MD5SUM_on_Windows

compare it to the md5sum for your ISO file here http://releases.ubuntu.com/oneiric/MD5SUMS

if it matches then great. what tool did you use to make the usb ? this one?
http://www.pendrivelinux.com/universal-usb-installer-easy-as-1-2-3

format the stick, make another and when you boot it, at the boot prompt, choose verify installation media and it will perform md5 checks on the files.
