But note, as these almost always fall under the "you have physical access" category, their security impact is generally considered low.As far as publicly known, it's likely that Stuxnet was originally spread via a security problem with USB. Also, I'd doubt the "physical access" category. It may just require a bit of social engineering ("I have the file you requested on this usb stick"). Considering that I'd strongly disagree classifying such issues "low impact". At least for pluggable devices, I'd consider such issues rather serious. It's another thing with PCI or other devices that require significant work to attach to a piece of hardware.
If you are using cvss2, the flaw itself should have a low impact, and how it will affect your environment may have a higher impact. See http://www.first.org/cvss/cvss-guide.html#i2.3. It's hard to give a single rating that can be applied to all scenarios because obviously in some environments, this is not an issue, while in other cases like public Internet kiosks, it can be a big headache.
