Shookie, use Shift+delete if you are using Nautilus (or I imagine any other filemanager) that will skip the .Trash folder and delete totally.
If you prefer to use rightclick menu for deleting then enable "Include a delete command that bypasses Wastebasket" in Nautilus prefs on the Behaviour tab.
Then go and hassle Ubuntu to fix USB devices using wastebasket at all, I know it bugs the hell out of me
