How to determine the short circuit in the microUSB cable?

Question

Software testing

Hello. Half a year ago, an incident occurred: the apartment smelled strongly of burnt plastic. After a short sniffing run, it was determined that the victim was a surge protector with USB sockets for charging smartphones, and the culprit was the cable. The latter was established exactly after a relapse - the bastard burned the front panel of the card reader and additional. USB ports on the system unit, before that they sinned on Chinese SF.
And the question is this: there are several dozen cables, among which, without standing out in any way, there is a recidivist. It is possible that he is not alone there. What is the simplest way to sort out working cables and short ones without burning another half of the remaining ports on the motherboard?
