Attack code for 'unpatchable' USB flaw released

Theoretically, it could affect any USB device.

In reality, my thoughts are:

The attack is going to be more trouble than it is worth in most circumstances. I highly doubt that somebody is going to steal somebodies usb devices and rechip them with a malicious firmware chip.

What would most likely happen is that special usb attack devices will be made to look like normal usb devices.

This attack, from what I understand would require physical access to a machine unless you give/sell somebody a malicious device. (Don't buy generic usb devices from China).
