USB Killer, wut?

Long story short, some Russian guy made USB-pluggable device to burn your computer; exhibiting high current on your USB port. Here's the story from Ars: http://arstechnica.com/security/2015/10/usb-killer-flash-drive-can-fry-your-computers-innards-in-seconds/

His personal statement are http://kukuruku.co/hub/diy/usb-killer (English) and http://habrahabr.ru/post/251451/ (Russian).

Most USB ports already have positive current limiter (simple diode to your GND, which serves as the current sink); this guy got around by using negative voltage on VCC or data pins (any pin will do given the high current); also supported by the fact that N-channel transistors allow higher current compared to P-channel counterpart on the same physical dimension.

Manufacturers better start equipping our USB ports with transistor-based current limiter making it dual-bias if necessary (adding another pair with reverse bias), or putting in some (small) user-replaceable fuses.

All in all, those small caps aren't that small!
