USB-C/3.1 Video and Linux

A couple days ago I got a Best Buy flyer, and they have this item: https://www.bestbuy.ca/en-ca/product/asus-zenscreen-15-6- fhd-60hz-5ms-gtg-ips-lcd-monitor-mb16ac-dark-grey/10737845.aspx? It's a portable IPS LCD screen from Asus. I have a similar item from about three years ago that has two connectors, one for USB power-only and the other for VGA/HDMI. There were other models at the time that used only one connector, USB for both data and power - but that required a driver (and would have been painfully slow if it was USB2). But now here's this new model: it's one connector only, USB-C. And presumably USB3.1. And USB3.1 can carry video. But at this point I get lost among the standards and their implementations and which one supports what. I have an Asus Zenbook (it's Linux-only at this point) that has a USB-C connector, but I suspect it's USB3.0. So the first question is: how do I check that? Second, does Linux support video-over-USB3.1? Do I need a special cable? Is this "Thunderbolt?" How can I check if my machine would support this? I admit that I'm probably not going to run out and buy this tomorrow as the old one is mostly sufficient for my needs, but I'm very curious about the state of Linux support for USB3.1 and Thunderbolt's many features. And I'd like to know if my USB-C port supports USB3.1. Thanks. -- Giles https://www.gilesorr.com/ gilesorr@gmail.com

The Spec you linked say it's DisplayLink, which is the software based video solution that requires a driver. https://en.wikipedia.org/wiki/DisplayLink USB-C is only a specification for a cable and connector, and somewhat agnostic about the data communications spec used across it. The cables are of high enough quality that they can support multiple data communications specs, generally referred to as alt-modes. https://en.wikipedia.org/wiki/USB-C#Alternate_Mode_partner_specifications Thunderbolt 3 for example co-oped the USB-C cable spec for it's cables, much like in the previous generations it co-oped the mini-displayport cable spec. Intel makes a point that a port carrying Thunderbolt 3 should also be cross wired with USB 3.X and Display Port hardware to output those signals as well. So if you want a monitor that uses a Type-C connector, your looking for a display-port monitor. Which your not likely to find in the portable market yet. -- Scott Sullivan

Thanks Russell, Lennart. I grabbed Fedora's very latest kernel this morning (4.15.12-301.fc27.x86_64) given Russell's point that there's been a lot of new feautures related to this. After a reboot I ran 'lspci' - I have USB3.0, not 3.1. This is backed up by the Zenbook manual. The manual calls the port "USB Type-C/DisplayPort combo port" and says "Use a USB Type-C adapter to connect your Notebook PC to an external display." I didn't find anything more specific than that, but it's promising. It'll probably be a long time before I test it though! I haven't got my head around the spec enough to know: does the fact that it's USB-C guarantee that it can deliver 20v and lots'o-watts to accessories? What about accepting that voltage from a charger? I'd bet that Asus hasn't bothered to set up that port to allow charging through it as the computer also has a dedicated old-style charger/plug combo. -- Giles https://www.gilesorr.com/ gilesorr@gmail.com

Well remember that to make things confusing, USB 3.0 was renamed to 3.1 Gen 1 by the USB 3.1 standard. So USB 3 now has: 3.1 Gen 1: 5Gbps (Was 3.0) 3.1 Gen 2: 10Gbps USB ports do not need to support the USB 3 PD (power delivery) spec. It is optional. USB 3 really has made USB very complicated (although also more useful). -- Len Sorensen

The spec for USB 3.2 was released last fall. This is what it looks like to me, so far. USB 3.2 "SuperSpeed+" is what will now provide double the bandwidth (2 gigabytes) over the existing USB-10gib/ 3.0, (1 gigabyte) bus. It does this by taking advantage of USB Type C connectors and vendors own (flip flop) logic. Logical states for a Type C cable are flipped, unflipped, twisted and untwisted. Endpoints may be ack'd either as a remote sink by their own servient demand for voltage or; in the case of "SuperSpeed+", the USB power lanes are co-opted for double the data rates. I suppose 3.2 logic will take care of all the possible signal switches, so you don't accidentaly send 100w to something asking for 15w. Since the specification allows for the data stream to contain timing bits, video and audio sink MUX is managable. As for Type-c DisplayPort video. The notes on Type-C connections & 3.2 host/sink protocols indicate that there is a fair bit of restrictive IoT type hardening going on; restricting firmware update requests etc. There is no reason not to use all that bandwith an connectivity for multi-media so its probably more a matter of when then if. So when it is decided on a single logo for an "omnibus" connectivity device and protocol stack, consumers will be able to say I can buy this because I can stream a movie to my device while charging it at the same time. Not my biggest priority, but people love the convienience. Where Linux distros may lack certain convieniences, they are replete with opportunities to do things in non standard ways that other OS's dont have. I think I just read that Windows 10 now has a virtual linux console. In 2000 I ran Win98 in Win4lin terminal albeit sans DirectX on a 300mhz Celeron OC'd to 500mhz. That was fun but pointless. I deleted Windows to make more room for Linux. It's more fun.

I thought USB C chargers were supposed to negotiate power and only provide higher voltage if the device was able to accept it. BTW, I recently bought an Asus ZenPad 10tablet. It came with a standard 5V charger, with a A connector and an A - C cable. I also recently bought a Google Pixel 2 phone. It's charger came with a C - C cable, but a 5V 3A output. So, it can provide higher current, but not voltage.

It's a portable IPS LCD screen from Asus. I have a similar item from about three years ago that has two connectors, one for USB power-only and the other for VGA/HDMI. There were other models at the time that used only one connector, USB for both data and power - but that required a driver (and would have been painfully slow if it was USB2).

The manual says it uses DisplayPort Alt Mode for USB Type-C. So if you connect it to a system that supports that mode on a USB type-C connector, it should just work as a DisplayPort screen. If your system does not support that, you can use any USB 3 port but you need a driver in that case to run it as a USB video adapter instead. Linux as of 4.6 kernel appears to support DisplayPort over USB Type-C at least on some systems. -- Len Sorensen
