The USB-C standard is still far from universal, yet it enjoys today a major new certification proposed Wednesday by the USB Implementers Forum. It is also almost a reset for this new connection intended to replace on our PCs and our smartphones previous generation USB.
For there was danger in delay. Launched a year ago, the first C-type USB cables have multiplied but obviously a bit anarchic. So chaotic that many of them can cause damage and permanent cripple the machines that are connected to it. This discovery Benson Leung, a Google engineer who is “entertained” for months in test scores, purchased from Amazon
The result:. A too high proportion of cables defective, disrespectful of the first criteria and therefore dangerous. A painstaking job that allowed Amazon to establish a black list of products that will sell more.
And to explain that it will stop distributing “All cables and adapters USB Type-C which do not respect
specifications standard USB Implementers Forum Inc “.” This is very good news, but we must all
continue to pay attention and to highlight the wrong products
we find on Amazon or other stores when we
find, “said the heroic engineer
Enough to clean This is doubtful.?: given the importance of this standard in the consumer, a simple black list may be insufficient to guide and alert customers. the USB forum therefore has decided to go further by proposing a new specification paving the way for an authentication system cables. History to filter the bad students.
It will therefore integrate a chip bringing together a number of related data cable
question, the manufacturer, the model, the type of cable, etc. These
Data is transferred to the machine before it establishes a
connection through the USB cable-C and thus allow the latter to
check that the cable meets the specifications laid down by
USB-IF.
cable do not have these certifications and therefore not having been
approved by the USB-IF will be inoperative on the machine. The approach will not prevent exotic manufacturers to distribute dangerous cables but at least it will not work on associated machinery because this cable authentication occurs before
connection between the cable and the machine, even if it is not
used for charging a battery with no data exchange.
To go further, a certification logo will be affixed on
cables to this specification. In short, the USB Implementers Forum intends to clean house before the USB-C becomes the world standard it claims to be.
