Video Out over USB Linux Mint Cable Matters SuperSpeed USB 3.0 to HDMI adapter

[firemedictj]

Hello,

I am running Linux Mint (cinnamon) and have purchased a

but the black one.

I would like to output the video to a tv to run Kodi. (linux native, not in wine).

I have a drivers CD for windows and Mac but I think that does not do me much good. I have searched online and found nothing about anyone trying this before. Supposedly there is some linux kernal support but it is unclear as to which kernal and how it is supported. If any one has any links or solutions that might help I am willing to give it a try.

Right now when I plug in the device it is not recognized by linux as far as I can tell (linux noob), and it does not output anything on the TV. The main screen and OS work just fine.

Open terminal, type 'dmesg', and look at the last lines printed when you plug it in. Basically you are going to want to look for whatever chipset is used in that monstrosity and what device it is being assigned to under /dev/***. You might just need to create a custom xorg.conf file. or maybe it is already detected and you just need to enable it in monitor settings, arandr, or similar software

[Edit] Not 100% certain but I guess this is a DisplayLink chip. [strike]ArchWiki mentions USB3.0 DisplayLink chips not supported on Linux.[/strike] Only supported for Intel video chipsets and kernel 3.17+

Question: Why are you bothering with this at all? Certainly your computer has HDMI, DisplayPort or at least DVI.

New USB device found, idVendor=17e9, idProduct=4301
New USB device strings: Mfr=1, Product=2, SerialNumber=3
Product: USB3 to HDMI
Manufacture: DisplayLink
SerialNumber King2711000000676

To answer your question, this laptop only has VGA output.
All outputs: 3x USB2.0
SD Card reader
Mgbt Ethernet
PCI Express (I believe)

Any ideas where to go from here?

It is a DisplayLink device. If you read the links I provided:

The USB3.0 chips are supported on kernel 3.17+ but only for Intel [Specifically only Haswell chipsets] video. Almost certainly you do not have Haswell chipsets...
Relevant Kernel commit:

I do not know if this has been merged for other intel chipsets, Nvidia, or[strike] ATI chips[/strike] It is currently being worked on for ATI chips.

You best bet is to get an older USB2.0 version of this device which are better supported.
