USB-C to HDMI - Huawei Mate 9 Pro Questions & Answers

Hi guys!
I've got a Mate 9 PRO with a powered USB-C hub. Whilst the keyboard, memory stick, mice etc. all work through the hub, I am not getting any HDMI signal from the hubs built in HDMI socket. Is it possible I need to turn something "on" on the phone?
Thanks!

[Q] Question about SlimPort

So the Nexus 4 doesn't have USB OTG support. That sucks. I'm fairly certain the answer on the following question will be "no", but I've still got hope.
With SlimPort, you can connect your Nexus 4 to a HDMI monitor, similar to MHL. It also charges your device. In my amazing Dell ST2220T touch monitor (well, the touch isn't so amazing, but the screen quality is), there are four USB ports. When I connect my Nexus 4 to my monitor with SlimPort, would I be able to plug in a keyboard and mouse in the USB ports on my monitor?
If not, I could use bluetooth (if you can connect multiple devices at least, both mouse and keyboard) or use the touch functionality on my monitor, but I'm not sure that works because it's a seperate cable.
It would be really cool to use the N4 as a sort of mini computer. Like Ubuntu had in mind. I can connect it to my speakers, to my monitor, I'm only hoping that I won't have to buy bluetooth accessoires. I prefer to use my wired accessoires, or if that isn't possible the touch functionality of my monitor, but I'm fairly both won't be possible.
the usb on your monitor would have a upstream connector that goes into your pc, so it won't work with phone,
you have to use bluetooth keyboard and mouse

So even if the N4 had USB Host support, I still wouldn't be able to use a wired keyboard and mouse together with the SlimPort, right? I doubt there's some adapter that can do both.
The slimport controller acts as a switch, it either routes usb or displayport signals though the data pins, the usb lanes are not connected while it's in use.
While displayport does contain aux pins for handling additional stuff such as usb (hypothetically?), those pins do not exist in our setup.

RAZRi XT890 USB OTG Capabilities (Thread for all Devices)

Me and few other people still asking about OTG capabilities so lets make combined thread for all.
What I figured out for now.
First of all RAZR i does not support OTG itself cause has no power on micro USB port so You need more than regular USB OTG cable.
You need minimum 1A powered USB HUB which means just buy regular 3/4/8 ports USB HUB but with 1A (can be 2A too) AC adapter.
So connection should looks like:
RAZRi -> OTG Cable -> USB Powered HUB -> USB Device
It's simple part. Lest make something harder.
List of devices which I tested:
USB HUB
KitKat should bring more OTG capabilitiesfor us so to prepare for that I bought new USB HUB with built in OTG support.
It the same like THIS one and it's dedicated for Samsung S3, S4 etc.
Hub is made not so bad, it has built in OTG support so no need other adapters and it has power connector.
To use this HUB You need to connect it to DC 5V/1A with 1,35/3,5 to USB cable. I used this cable and regular Moto wall charger. You can also use power bank as power for more mobility.
All my USB devices working fine under this HUB so I can recommend this for RAZRi.
Mouses and Keyboards
RAZRi has no problems to detect and handle with most of mouses and keyboards. No modifications are needed. Just Plug & Play.
USB Drives (Pendrives, HDD's etc)
Unfortunately none of them are working. Phone detects devices in some apps but drives are not detected as drives, just devices and they can't be mounted. I think without any kernel modifications drives can't be mounted. Apps to mount drives can't handle with it too.
USB Audio Devices / DAC
Unfortunately I have only 2 devices like that. Sound Blaster Surround 5.1 USB and Logitech Stereo USB Speakers.
Both tested with USB Audio Tester ROOT.
Creative is correctly detected but there is no sound on every setting.
Logitech USB speakers are detected correctly too but I was able to make it works but only to hear sound from internal microphone. No way to hear music or any sound from phone.
I tested SoundAbout Pro tp force playing from USB host but it failed. I don't know any other app can make it. Also I'm really noob at Linux so I have no idea what to modify in Alsa driver to redirect sound on USB audio device.
USB Game Controllers / PAD
I have only wireless XBOX360 pad so can be hard to make it work but heard somewhere that can be possible. In few days i'll check what can be done with it.
Tested with Logitech Cordless Rumblepad 2, working like a charm without any mods. OFC You need to use button mapper or any similar app cause after connect pad is working like mouse but after remap we have fully working cordless pad.
USB Network Adapters
At this moment I tested only cheap RJ45 to USB adapter but it doesn't work. Strange cause activity led on adapter is blinking sometimes and it stops when phone is off but nothing except this.
Any other news, suggestions, tests of working devices are welcome.
Network adapters updated.
Wysłane z Motorola RAZR i.
You need to mod the kernel to add usbstorage like the samsung S3 and the framework apk i think, maybe some hardcore developers can help on it.
xbox 360 controller is detected as device but is not working something is missing cuz i added the keylayout for the device and is not working. but you can remap any keyboard keylayout to work as joystic XD.
Updated GamePads section.
USB HUB with OTG added.
Very nice, I tryed, and it works like a charm. I could use a keyboard and mouse runing Ubuntu 15.10 on CHROOT

Let's get our M.O.J.O. on(line)! Post pics your M.O.J.O setup!

Here's my simple little setup. Consists of two Logitech F310 controllers, Seagate 2TB USB 3.0 had drive, Pluggable Peripherals 7 port hub and of course the official controller. Also has a keyboard and mouse dongle plugged in. I'd love to see others. Post em! (BTW, forgive the white extension cable, it is actually connected to the hard drive as I am in the process of backing it up)

6months old photo, but still using the min combo BT keyboard, charge the AAA batteries on the TV usb with the USB hub under it.
And I keep the mojo on it's side.. i think it looks cool and lets the heat rise.

I wont recommend the mini nor the micro (button keys instead of real keys unless it a remote maybe), it's okay for quick surfing/emailing but not for chat etc.. great for my travel bag.. but I would use it more if was more fullsize... I need to replace my old wired keyboard mouse.. so i'll be looking for a fullsize BT combo.
From top left:
AverMedia Capture HD II C285, MOJO 4way USB hub, 32GB roms, cheap twin PS clone controllers on one USB, Behringer headset for late night gaming sessions.
My old USB keyboard and MS laser mouse, 7inch Hyundai T7s, Travel clip with my tablet mod.
MOJO CTRLR, retail CTRLR, Shintaro Mini Bluetooth Keyboard.
And under the TV I have a 4way USB hub powered by the TV's USB port.
Attached are two USB AA/AAA battery chargers and a retractable USB cable for the mini combo keyboard to charge.
Not that much really

video out to a usb conector, possible?

I have a slimport cable and it works great for connecting to my tv and watching stuff, but, I've just bought a new car which has a half decent screen in it (well, slightly better than the phone) and I know other android phone users have had video playing on that screen. to do it they need the phone to do all the processing (car screen to be just a dumb screen) and they use the car's usb input. So, I'm wondering ...is there any kind of slimport to usb instead of hdmi cable, or is there a male hdmi to male usb adapter that I could use to connect my slimport to the car usb slot? ideally something that's cheap as I won't know if it will work until i plug it in.
thanks for any ideas.

Reliable HDMI CONNECTOR

I've tried a couple of devices that claim to connect V20 to tv by wired usb c to HDMI connector. They work for a while then the picture is lost or the phone itself freezes up. About the longest play I've gotten successfully is an hour but usually something goes wrong within 15 minutes.*
The phone has been out over 6 months now so I thought someone may have found a really dependable HDMI connector? I don't mind the lack of power in because I can always change batteries but phone should be able to play through HDMI long enough to watch one movie. That's all I really need hut I don't want to have to screw around with it 10 times to watch one movie.
Thanks so much for your help!
I've been wanting to make use of this feature, but haven't extensively yet. I have though gotten to make fair use of a micro-USB to HDMI adapter. A few trouble spots come to mind here.
Sounds like you're powering the adapter/phone from an external power source? How good is that power source? My micro-USB to HDMI was distinctly less reliable when plugged in since I was merely powering it from a normal USB port. Try running it entirely from the phone's battery. If this works better then it could be you really need a higher power source when using the adapter.
How good is your HDMI cable? Depending on how strongly the phone/adapter drives the HDMI signal, a lower quality cable could break the camel's back.
I've been running into a different bit of trouble with USB-C to HDMI adapters. I've found several of these, but whenever they've got a USB-C pass-through, the pass-through is strictly for power and does not carry the USB signals. The MyDP specification allows for USB3 to be passed through if 1 or 2 pairs are used for the HDMI signal, but allows for USB2 to be passed through no matter how many pairs are used for the HDMI signal. There are adapters which also include USB-A port(s), yet none which include an external USB-C with the USB signals. Grr!
I use C to HDMI not micro usb. V20 doesn't use micro usb. It uses slimport. I have one adapter which allows simultaneous charging and one strictly slimport C to HDMI. Both behave the same way. I have a high quality 2.5 foot HDMI wire.
Power source was Samsung tv usb powered output 1 amp. Point is I have the same issue with pure slimport and no charging.
The one that allows simultaneous charging does in fact charge and work but always craps out but so does the slimport C to HDMI.
Hmm, entertaining what you find when you do research. I suspect the V20 is using the "MyDP" specification, which is the official specification name behind "Slimport". Seems there are at least two other video out methods for USB-C.
I haven't done enough with the video-out feature of my V20 to have much experience yet. With a V10 whenever an adapter was plugged in without external power there were no problems, but when an adapter with external power was plugged in video wasn't reliable.
I'm interested in reading if you find out anything.

Sorry I haven't tried, but its seems to connect smoother the a wifi dongle.
does anyone know if there's a compatible dongle for the V20 with not only hdmi but also power input and usb host?
Happening to me too - Any suggestions
Your situation's description fits my problem exactly. I have a USB C to HDMI that was vouched as working by several V20 owners. I plug it into my Dell monitor to play games on a bigger screen. It works well for a while, then disconnects and popup on my screen says something like, "LG Bridge has stopped working do you want to exit?". Once this happens, it's almost impossible to get the V20 to share the screen again. It's not a hub, just a USB C (male) to HDMI (female).
