Free Software Will Help Detect Faulty and Malicious USB-C Cables
Reader Mickeycaskill writes: The USB 3.0 Promoter Group, of which HP, Intel and Microsoft are members, has developed authentication protocols for USB-C and will offer free software to detect faulty or malicious cables.This tool will alert users if they are using a non-authenticated cable. It has been suggested that hardware manufacturers could ship devices with an authentication system already installed. It is hoped that the specification will help end a number of recent incidents where sub-standard cables have either ripped off buyers or damaged devices. Most recently, Amazon said it would be adding USB-C cables and adapters that do not comply with standard regulations to its list of prohibited electronics items.
There have been bad cables out there that put in the wrong spec resistor or are otherwise mis-wired. However, I don't agree that "authenticating" the cables is the answer. The word "authentication" implies that there will be key exchanges involved, which puts all the pieces into place for vendor lock-in (i.e. LG devices only charge with LG certified cables, etc... ), not to mention additional cost and complexity. I for one already have a selection of USB-C compliant chargers and cables (yes, using Benson's spreadsheet). Will those be accepted by new USB-C devices supporting this specification? Will there be a supply of cheap USB-C cables that support this "authentication" AND work with every device vendor? I doubt it on both accounts. I prefer Benson's approach of shaming the vendors that don't follow the spec.
