Sure, if you're the one who created the USB drive then you could make it not actually a USB drive. But this sounds like an infected machine infecting previously safe USB drives and turn them into malicious ones. And I'm not sure I get how a USB drive can be turned malicious. I vaguely remember there was a bit you could flip in older USB drives to make them appear as disk drives and enable autorun, but I doubt that's how this is done.

Once you can manipulate the code on the firmware, its probably pretty easy to find a kernel level exploit. Here is a reference with a virus. https://superuser.com/questions/854918/manipulating-firmware-of-usb-flash-drives https://superuser.com/questions/854918/manipulating-firmware...
