USB Implementers Forum, the support organization for the advancement and adoption of USB technology, today announced the publication of the USB4 specification, a major update to deliver the next-generation USB architecture that complements and builds upon the existing USB 3.2 and USB 2.0 architectures. The USB4 architecture is based on the Thunderbolt protocol specification recently contributed by Intel Corporation to the USB Promoter Group. It doubles the maximum aggregate bandwidth of USB and enables multiple simultaneous data and display protocols.[…]
As the USB Type-C connector has evolved into the role as the external display port of many host products, the USB4 specification provides the host the ability to optimally scale allocations for display data flow. Even as the USB4 specification introduces a new underlying protocol, compatibility with existing USB 3.2, USB 2.0 and Thunderbolt 3 hosts and devices is supported; the resulting connection scales to the best mutual capability of the devices being connected.
How many years until USB4 (or later) replaces HDMI and DisplayPort? Since everything is data packets now – analog is a thing of the past – do we really need to have separate video cables? I’d love to one day build a PC that just has an array of USB-C ports on the back, with the ability to plug anything – monitor, keyboard, mouse, serial port adapter for the Windows CE mini laptop I’ve been craving to buy for ages, you know, the usual stuff – into any of the ports.
One can dream.
As far as I’m concerned, micro usb, while a marketing success, was an engineering failure. It was shoddy and after a hundred normal uses electrical contact and grip would fail. Mechanically micro usb was just too fragile and never deserved to be a USB standard. The usb port/cable on all of my microusb devices either failed or were on their way. Some might accuse me of being too rough, but even a slight pressure over time would cause the pins to eventually loose contact. On top of this, it was too hard to tell the orientation in the dark.
Apparently a lot of manufactures agreed it was terrible and many of them stuck with miniusb or the old usb type b for non-phones peripherals, thankfully!
IMHO USB-C is a good standard though and I’ll be happy when microusb finally dies.
I agree this ought to be possible, but you’ve got various consortiums who don’t want to give up power or become redundant so unless they find a way to rise above the politics, I’m not sure this will happen.
And then you’ve still got things like ethernet ports that still need magnetics for long distance transmission.
