Hey guys,
I'm using my tablet in my car and have it connected to a Kenwood radio which has two USB ports. The radio can recognize the android device and changes automatically to USB as an input and then my steering wheel controls don't work anymore.
So as a workaround I bought an USB adapter which only connects the power pins. But with this adapter, the tablet is not charging. The cable itself is working as intended with another phone, so it has to be something special about the tablet.
Does anybody know if there is a way to use a data connection via USB to only give power to the Z2 tablet?
Man, somtimes I'm just an incredible idiot. The Xperia Z2 Tablet has a dedicated charging port at the bottom for which I already have a cable. So, I'm going to use that.
Sometimes the solution is so damn obvious

Hi together,
ive asked me if it is possible to use an adapter for 1x micro usb (plug) -> 2x micro usb (jack).
Could the phone handle 2 USB devices at the same time?
Maybe then it is possible to use the HDMI output and the USB host parallel?
For example to use an TV as screen and an HDD as the source for a movie.
This would be nice.
Thanks in advance.

When the connector is used for HDMI I doubt it can be used as USB at the same time, I'n sorry.
Maybe in a few months cyanogenmod provides a hack, if there will be an dual adapter soon.
We will see. Thank you.

The hardware needs to allow this if it'd become possible. You need a really smart USB dongle that knows how to split the HDMI output from the USB output.
Sounds a little too difficult to ever happen.
Hmm thats right. I think i still dream xD
But thank you.

it is not possible. because as stated on this forum many times before, the type of usb connection is determined by the resistor between pin 4 and 5 of the micro usb connector. the strength can tell the phone, that there is either a charger, a pc connection, car kit, jig, usb otg or mhl connection present.
and i believe, this is an important thing to keep in mind for so many things:
for instance, why the original car kit triggers car mode and generic car charging cables don't or why not just any micro usb male to usb a female will work as a otg cable or why flashing should be done with the original usb cable...
so if you were to buy or build a micro usb hub, since it has no resistor in the very plug that connects to the phone, it cannot be used for anything but charging and quite frankly, i wouldn't connect more than one charger to the phone.
however, if you want to use your phone for presentations or watching movies and still be able to use it, get a bluetooth keyboard and mouse or a bluetooth presenter or do it the other way around and use a usb input device and transfer your media using allshare. everything else is physically impossible, so neither CM nor XDA can do anything about it. the only device that can do what you want is the new motorola. it has a separate micro usb and micro hdmi port and a docking station, so you can use it as a full notebook.
Thats obvious. Thank you.

I want to have S2 with usb keyboard, mouse, (probably a pendrive/hdd also), and a hdmi screen connected while charging the battery. My question is, what cables/adapter and usb hubs would I need to achieve the desired configuration?
As far as I know, what you want isn't possible. The MHL/HDMI and USB are mutually exclusive -- they share a connector, and when the MHL/HDMI adapter is plugged in, the connector switches into MHL mode, and the USB data pins are re-purposed.
you can't, maybe a bluetooth mouse/keyboard will solve part of the problem. And maybe you can use a powered hub to use them together, but not with HDMI
The phone differentiate MHL, USB,USB jig, and charging mode (AC vs dc) via resistance between two of the connector pins on the cable. So one mode at a time.

Could this phone potentially be able to charge, be HDMI out and be connected to a keyboard and mouse all at the same time? Or can you only do some of these features? I Saw the video of the phone being connected to multiple devices but how about everything all at once?

It cannot be connected to MHL and USB OTG at the same time, but you can do everything you mention with an MHL adapter (which has, and requires, a charging input in order to be able to use it), and a bluetooth keyboard and mouse.

So you're telling me that it can only do Video out or read/write to USB devices but can't do both at the same time?
The reason I ask is because I'm thinking of designing a board with its own power source so that it only requires to read information from the 11 pins to accomplish everything.
I want to charge the phone, have a few USB ports and a HDMI port and have the phone interact with all. I just don't know the specs of the board or what is going on. Maybe I need to get in touch with superico.
Hi guys, I have a problem with my Asus Z380KL tablet. Im want to use this tablet as a head unit in my car and I need to use OTG cable to make it work, also I need to have charging in the same time. I also want to use AutoMate app to control tablet, especially auto on/off while charging/not charging.
And now is the problem, I can easily achieve working external devices (usb dac, FM transmitter and pendrive) with charging in the same time, problem is when I cut off the power from charger tablet still thinks that is charging, of course it cant be cause there is no power source but still I can see charging icon and in settings showing that is still charging. It stop doing that when I unplug micro usb plug from tablet but obviously I cant do it all the time cause tablet will be build in dashboard.
Now, with normal charger, without OTG cable its working perfectly, when I cut off power it stops charging in the same time, also I tried couple OTG cables and on every single one is the same thing.
Any ideas guys how I can fix that? Im not sure if thats software of hardware problem.
Also device is not rooted and it has ASUS oem software with Android 6.0.1.
Thanks guys for your answers and your time! Cheers

Really nobody knows what could be a problem?
Hi!
Background:
I'm an esport producer and after some nightmare productions I'm really excited about the rog phone as it seams to be the only phone that have the features needed to make it into a good esports phone (e.g. Having 8-10 players competing in from of an audience), mainly: Hdmi output, ethernet capabilities and usb-c ports on the side..
Problem: After first successfully testing out Hdmi + ethernet connection I wanted to try if I could use the fan accessory and still be able to get the Hdmi signal from it.. When I connected the fan it told me to update the fan firmware so I did, but after that I'm not able to get Hdmi signal either with or without the fan accessory.. For instance, when I plug in my portable asus laptop monitor (power and signal from usb-c) the monitor starts to boot up and then dies.. Then tries again and dies and so on.. On my Samsung s8 it works fine.. So I'm guessing the firmware limits the power that the phone can output on the usb-c port.
Question, has anyone else experienced this issue? Is there a way to uninstall the fan firmware update (that obviously did not only affect the fan but the phone as well). The Hdmi adapter I used was something very similar to the professional dock but is actually an usb-c dock ment for laptops..
Tl:dr; hdmi doesn't work after "fan firmware update", plez halp.

Just a small update,
I was able to get it to work if I disconnect the power cable from the USB-C dongle and then connect it again.. and sometimes it also requires me to disconnect the HDMI + reconnecting that as well.. so I'm not sure if this actually was due to the fan firmware or just a result of a... weird bug(?) when it comes to the OTG features of the phone.. because connecting the dongle with both HDMI + power already plugged in does not work.
Anyway, just wanted you guys to know that it does work, just need to randomly connect/disconnect cables from the dongle first =)
Best regards,
Which USB-C to HDMI adapter were you using? I am looking for one that works with this device, aside from the fairly costly pro dock.
