Let's say I connect my smartphone's micro USB port to a micro HDMI port of a video handycam, with a MHL cable.
I need to know:
- The pin mapping done by the mhl cable- namely what usb pin is connected to what hdmi pin (I couldn't find on the net).
- How can I capture the audio/video signal output by the camera, with the phone through its micro USB port (I want to write the driver for that).
We suppose the phone doesn't have a dedicated MHL chip (even if it had one, it would be for output from the phone not for input).
Also, I don't want to use Wi-Fi.
Any hint is appreciated.
Thanks.

So I bought a USB Female to microUSB male adapter for my phone and I was wondering what peripherals I can use with it.
I tried the XBOX 360 adapter that works with the tablets but it doesn't seem to work on my phone. Are there any that WILL work?
Just changing the "gender" of a USB device does not change it from being a slave device to being a bus host.
Unless you have a patch/ROM/hack that allows your device to work as a bus host (and I don't know of one for the Galaxy S4G), then you can't connect "peripherals" to your device, no matter how computer-like it seems to you.

Think I need a mini HDMI to HDMI cable, a Micro USB OTG adapter and I should be sorted. Optionally could add a USB hub to allow me to use a USB to Ethernet adapter and a couple of other USB devices (such as a keyboard, mouse).

Hi,
I just bought a similar to this Type-C to HDMI and USB Adapter for testing DeX. I didn't want to buy an expensive adapter, because I'm not gonna use it very often (maybe this changes, when Linux is ready).
I works great, I also connected my Logitech k400 without any problems.
So I tried an USB 3.0 hub with card reader (3x USB, 1x SD, 1x Micro-SD) to it and DeX doesn't show up anymore.
The S10 still shows, that DeX is running but my monitor goes black.
Does someone know how to fix this? Is this a general DeX related issue or just adapter related?
EDIT: Found out that it's working when I connect the hub before connect the "DeX" adapter.
I have a keyboard and a mouse that both have their own Bluetooth-USB adapter.
I also have a new Android STB that has only one Enthernet and HDMI connector.
So therefore I wonder if it is possible to connect them through a USB hub with Enthernet-port via Enthernet,
so that the Blutooth adapters can be used.
I would like to use both adb via USB (not via IP) and HDMI out on my S22U without root but it does not seem possible and was wondering if there was a hardware (or other) solution to support splitting up HDMI and USB or at least making it seem like an HDMI out device is connected.
I tried multiple USB hubs that have HDMI out and USB, but it turns out that connecting Android to a PC via the hub will not work due to usb host/master/slave issues. I'll probably also try a USB over IP solution like VirtualHere but I don't have high hopes for that.
