[Q] MHL Adapter not working on Samung Galaxy Note N7000

Hello All,
Search quite a few threads on xda as well as internet but unfortunately nobody have been facing issue similar to mine.
Okay, let me put it in brief. I bought an original samsung mhl adapter for galaxy s2 from ebay which presumable works well with samsung galaxy note too (haven't seen any MHL Adapter specifically for galaxy note) as heard on forums and web. It did not work. So, i got back to the vendor and he replaced it to me with another MHL Adapter. That too did not work. I got a refund as the vendor was good.
I still somehow wanted the MHL to work so went to a different vendor, known for good products (i.e. flipkart) and purchased another MHL adapter after confirming with the executives that yes it would work with galaxy note. It too isnt working.
In both the cases, the phone gets charged but there are no such notifications (notifications such as USB Host Cable Connected, or Keyboard Connected or MHL Connected etc). I have a working HDMI 1.4 cable (tested and verified), and yes, i am aware that external power is required to the MHL Adapter. .
Now, every other functionality on my phone is working well, like USB Host Mode, bluetooth/usb keyboards and bluetooth/usb mouse, data sync via usb etc etc, its only the MHL adapter which is giving me an issue constantly. Can the micro usb port on my Note be faulty ? I dont think as every other options are working fine.
I have tried all the three MHL Adapters (2 from the 1st vendor and 1 from the second) after i upgraded my phone to ICS. Are any other users facing the same issue ?
Any help is highly appreciated.

Apparently, there are problems with MHL support on ICS.

MHL adapter regarding....
hi guys,
i am also facing the same problem with MHL adapter. i tried to connect my galaxy note n7000 to sony bravia 3d tv via MHL but failed to do so. whenever i connect MHL to HDMI Cable to tv and to phone nothing happened and not even my phone or tv show any sign of connection or any notification regarding that. my phone not even show the battery charging sign. i also used 3d HDMI cable for the connection but nothing came out.... and when the vender (from whom i purchased the MHL) gave me the demo the same MHL was working fine with his HDMI cable and tv but the cable and tv he used were not 3D whereas i have a 3D tv. i dont understand why i am not able to connect the MHL adapter using 3D HDMI cable to my Sony Bravia 40HX750 3D tv with my Galaxy Note n7000. still struggling with that.... any reply in this regard will be appreciated.... thanx.

USB Wireless Keyboard/Mouse

Any reason why the shield won't recognize my usb wireless keyboard? I can connect a wired Xbox 360 Controller through my OTG adapter, but when I connect the usb adapter for the mouse/keyboard, it won't recognize that there is a keyboard & mouse connected. My nexus 7 recognizes both when I use it, and so does my galaxy note 3. I'd love to be able to use this as opposed to having to buy a new bluetooth keyboard and mouse.
I'm using a logitech k400 keyboard with the touchpad and a logitech wireless mouse, model mk215, and they're using a unifying receiver.
I went to Best Buy and picked up a Dynex 7 port USB hub that is powered externally, and so far, the powered hub is not making a difference. Still not registering that the wireless keyboard/mouse are connected. Confirmed that hub works when connected to pc as well as my nexus 7, but not on the shield.

This will be supported in the update Monday its in the notes on things updating

I just did the update and plugged in a mouse via OTG cable and it seems to be working fine. Makes stuff like Plants vs Zombies really playable having a mouse.

I'm using a K400 and it works just fine. Both the keyboard and mouse pad are working great. I plugged in the OTG connector with the dongle already plugged into it and it wasn't recognized. I had to first plug in the OTG cable and then plug the dongle into the OTG.

The logitech unify devices work great with the Nvidia Shield.
HOWEVER, you MUST install the latest Unify software on a PC, link all the Unify devices to the same Unify transceiver you are going to use in the Shield. After linking everything you want to use, then unplug the Unify dongle and plug it into the Shield.
Why can't these instructions be included somewhere in the Logitech manual that came with my keyboard. What a waste of my time.

[Q]Android not communicating with Dual Shock 4 controller using OTG cable and Sixaxis

So I have a rooted Samsung Note Pro 12.2 and I am trying to get my DS4 controller to work on it.
So I tried connecting the controller through Bluetooth. It sees the device but won't connect. Then I tried using the OTG cable and still no luck.
So just now I bought the Sixaxis app but it says no controller found (even though the controller is plugged in with the OTG cable).
What is going on?? I have tried 2 different OTG cables, 2 different mini USB to regular cables. I thought since I am using a OTG cable I don't need the Sixaxis app.
Please help

6.0.1 OTG USB ethernet issues

Hello,
before I begin explaining my issue, I would like to apologie for my bad english.
I sometimes like to use my phone like notebook: connect mouse and keyboard to it. Z3 have OTG capability, so it(s fine. But one thing is not: ethernet adapters after updating to 6.0.1 using this doesn't seems to work.
First of all: i've thought, that you either have OTG or not. Not just for some devices. That it works like regular USB. It seems not. I have USB 3.0 powered hub conected to OTG cable and to the hub I've connected keyboard and mouse and tried to cennect already 5 different USB 3.0 gigabit ethernet adapters. They didn't work. On Android 5.1.1 worked my (all in one) USB OTG ethernet hub (3 USB 2.0, ethernet connector, micro USB wit OTG), but it was not powered, so I decided to upgrade.
Why? Simple. Power. I do this because for few day in near future I will be without my notebook (dedicated GPU is broken, i will have new one). I've been like this already for 3 days. And if i've been using my phone with keyboard and mouse (only use, which is comfortable for long time), I've noticed that is not possible to run this on battery. So my idea was to take as much as i can from the phone: controls and internet connection, and power that externally. And in addition buy the docking station and use the dock charging port. I've did all of this. And it works like magic: phone is powered from charger. All the time you might ask, why the hell I just don't use built in WiFi. Energy. That is the reason. WiFi just eat too much: if I pull up brightness of display and actually DO something on that phone, even wit plugged in docking charger, it just drain power faster, than charger charging (measured). For some reason the dock charging give about 0,45 A, not full 1,5 or something like that. Keyboard and mouse eats about 0,3 A, with some ethernet adapter it would be about 0,5 A. SO…a lot of power.
Android is based on Linux, so I have question (and I pretty much know the answer): is there ANY way how to install drivers for ethernet adapter on Z3? I obviously have root, I know about some terminal apps. But if I google this, it gives me only how to install drivers for phone on PC. That is not very helpful. I thing that this is most likelly impossible.
So I've searched something like list of supported devices. No suprise there: no relevant results. Sony Z3 AND Android 6.0.1 AND OTG device list, is probably too specific question.
Another idea what I had is try to use USB 2.0 adapters. You see, I wanted USB 3.0 (even though Z3 have only 2.0 (I still don't get it. Why the hell?)), because they have 1 Gb networks and I could use this adapter sometimes later for different device, like super thin notebook (if I ever would need some light device for travels). Another thing is the fact that 100 Mb is slow for large file transfer (movies and so on, so I have some entertainment, when I will not have my ntb). USB 2.0 can handle up to 480 Mb (in real life more like 300 Mb tops), which is still more than that network. But at this point I just gived up on this, and I will be happy if any ethernet adapter will work.
SO…do you know about any custom ROM, which would handle that? OTG USB ethernet support. Because not even that thing, which worked under 5.1.1 doesn't work under 6.0.1.
Sorry for long post, I needed to give you lot of informations, and why's.

Update
Update 0: OTG USB ethernet adapters doesn't work only on 6.0.1 or on this based ROM's. USB 3.0 doesn't work at all, but USB 2.0 works just fine on 5.1.1.
So…5.1.1 is most likelly the version, which I will be using. 6.0.1 has certain advantages, sure, but to me it seems like completely stupid to remove support for OTG USB ethernet adapters. More devices should be supported in nwer version, not less. And the inablity to remove bloatware even with root… No, this is just wrong. SO I buy my phone, but I have to have some apps, which I don't want and don't use? Ehm…no?
Update 1: I've decided doing it little bit differently. I've installed this ROM. I like how debloated it is, and many other things. USB ethernet adapter doesn't work (obviously), OS doesn't even know that something like ethernet exist. So I decided to try build my own drivers (by compiling source code) or app, or something. Any help is welcome.
Update 2: I currently have this thing. It's just USB 2.0 and 100 Mb/s, but…whatever. Tested on 5.1.1, transfers was 3× faster than on Wi-Fi and batery-enery-usage free (this is why I do this). Now, as stated before, I am on 6.0.1. That ethernet adapter has source code drivers available here. But here is the thing: they keep saing that
the support of this function must be included by the manufacturer directly in the particular Android device

(source) and the source code page saying that it is supported up to Android 5. So…what has changed in Android 6? Why the support is gone? And what will happend if I will try do something in Android studio?

Hello do you have z3 or z3+? I used to Havre z3 and with Lollipop ethernet became broke after 5.1.x I think so I had to reroll kitkat..I gave it away and now I am thinking to buy one z3+ but was fearing Ethernet won't work because it comes delivered with lollipop but now your post gives hope that it is still available. Other phones also have Ethernet capabilities but I found Sony best ... only the loudspeakers are not clear enough for me ... here you find a list with models that support Ethernet

Hello, I have also tested ethernet adapter and it does not work with 6.01 on xperia z1, huawei p9 lite, lenovo yoga 3 tablet.
In xperia z1 with 5.1.1 it works correctly. Something has happened with 6.01 but anyway not all phones or tablets with 5.1.1 work because lenovo yoga 3 with 5.1.1 does not recognize the ethenet adapter.
I think the manufacturer is responsible for not working when it does not integrate the necessary drivers and does not support ethernet. It is the conclusion I came to verify that not all 5.1.1 recognize ethernet adapter and in 6.01 I read that some if you comment that the adapter works (especially in nexus and motorola).
What would be interesting is what comrade BiPentHexium says to be able to include in our room the ethernet support being root.
---------- Post added at 01:09 PM ---------- Previous post was at 01:01 PM ----------
On the list of models that support the ethernet adapter, it only refers to the Plugable brand adapter and is based on the reports of its customers. But in that list does not appear the xperia z1 and I can confirm that it works correctly with ethernet adapter (I do not have the plugable)

Android tab which supports OTG and charging at the same time

I'm looking for devices (Android tablets) which supports OTG (to connect slave-devices, e.g., a mouse) and charging at the same time
There was a thread about Nexus 7 https://forum.xda-developers.com/tab-s2/help/usb-otg-charge-t3588019
It needed a custom kernel to get OTG+Charging working
But it's very old, you can't buy a new Nexus 7 anymore
Also someone mentioned about Samsung tablets:
Samsung tablets for sure can support OTG Host/Charge for a tablet and peripherals. Here is a list of supported tablets:
Samsung Galaxy Tab A (10.1″)***
Samsung Galaxy Tab S2 (8.0″, 9.7″)
Samsung Galaxy Tab E (9.6″)*
Samsung Galaxy Tab A (8.0″, 9.7″**)
Samsung Galaxy Tab 4 (8.0″, 10.1″)
Samsung Galaxy Tab S (8.4″, 10.5″)
Samsung Galaxy Tab Pro (10.1″, 12.2″)
Click to expand...

But these devices are also quite also and Samsung devices aren't that cheap anyway (if buying a new model)
So... Are there any devices (on sale) with normal prices which support OTG and Charging at the same time?
It doesn't matter if there is one port (input) or two (one for OTG and one for charging). Some Windows based tablets has a separate port for charging

Does Samsung Galaxy Tab A 7.0 (quite cheap) support OTG+Charging at the same time?

What you need is a "powered USB hub", it has its own power supply and it will allow you to connect multiple USB devices(mouse, keyboard, flash drive, etc..) and charge the device at the same time by connecting your phone charger to the hub at the same time.
I use a USB to microUSB adapter, then connect the adapter to a USB hub that has 4 ports, then I use the adapter to connect the hub to the charging port on the device, then I connect a keyboard, mouse and phone charger to the USB hub.

There is no such hub... At least officially. You won't find much. I saw one hub, but users said it was working only with Windows tablet (OTG+Charging), for Android OTG was working only
just google "Android OTG+Charging" you you'll it's quite a problem

Something like this won't do the job?

Or this:
https://www.amazon.com/dp/B00VK9C24M/ref=cm_sw_su_dp
Of course, the device must support OTG and the accessory charging feature. If it doesn't, I'm not sure there is anything you can do to force it.

You have to test first
Does this hub supply a tablet with power or connected devices (slaves) to tablet? I need to charge a tablet and not connected devices (connected devices can get power from tablet)

Well... manufactures don't give any information if their devices support all of this and what customers have to do to get it working (buy a specific hub or something else)
It's been two days and I only got reply from you. So we can say that it's not that easy and we can't be sure what to buy. I don't want to waste money if it's not going to work
Would be great if someone could really tell me which devices (tablets) support this feature, which hub should I get for such devices and so on

Did u have any luck with this?
I am looking for the same thing. So far I tested a fire 7 that did not work.
It seems like usb c tablets might be the answer. Seen a post that mentioned a version of the note working this way.
I might give the galaxy tab a8 a try.

I'm building a list of those known to work and not work: I can't post the link.

Devices which have a separate DC in power jack and support USB OTG (WIth any OTG cable, does't need ACA)
iRola 7" tablet. Very old.
E-Ceros Create 2 Tablet. Old
Ainol Q88. A newer version of this with Android7.1 and 1GB RAM is apparently still made. $53 It's said to support USB OTG (at least for a 3G adapter) and pictures clearly show a DC power jack, although the adapter may not be included. It is typically sold as a childs toy, but the protective rubber covering peels off to reveal a black plastic case.
Cube Talk 11 3G Phablet $85?
Raspberry Pi
Known to support OTG but NOT while charging: This limits OTG to either very short periods of use
Amazon Kindle Fire 7
Asus T100TAM
LG Nexus 5
LG Nexus 7
Samsung Galaxy Note 4
Samsung Galaxy S7
Samsung Galaxy S8+
Samsung Galaxy S9

Thanks for the summary. I am also looking for android tablets that support USB host and charging at the same. A few old tablets from LG and ZTE have both micro-USB as charging port and a full-sized USB port to host other devices. But they are quite old. So ACA cable might be the way to go.
Question: Do we need to patch android os as described here use ACA cable?

"You can lead a horse to water, but you can't make it drink."
You can always offer power to a hosting device.
Whether it takes it is another question.
If it's rooted you may find that you can control something to make it take it.
I've used back-powering hubs to power Androids.
This is a hub that has been modified to present power on the upstream port.
You can modify any powered hub to do this.
See: https://forum.xda-developers.com/showpost.php?p=25639514&postcount=8

Has anyone come up with any solutions to this problem? I see this thread is a year old but I am here with a samsung tab A 8.0 2019, I have the exact same problem. I need to an external usb in service while charging, not one or the other.

The use of a specific value resistor on the USB OTG ID pin to ground is pretty manufacturer specific.
Some devices have up to a 5 bit non-linear converter on the ID pin to give up to 32 modes.
I've found Samsung to be a fan of using the OTG ID pin.
I would definitely try values from short to 1 k to 1 M (in an exponential progression).
I don't even remember which device this is, but it gives you some idea of the values they might use:
Code:
0
2000
2604
3208
4014
4820
6030
8030
10030
12030
14460
17260
20500
24070
28700
34000
40200
49900
64900
80700
102000
121000
150000
200000
255000
301000
365000
442000
523000
619000
1000000
Open
If you're rooted you may be able to control the charge controller directly.
Some of this could be a pain if you were plugging/unplugging all the time.
If this is some hard-wired, fixed usage you could definitely hard wire your own 4 V charger into the battery.
You might try getting a few pots 10k, 50k, 250k and some 220k resistors to try your luck.

Whoever is reading this I can assure you that the Samsung tab A does not charge while OTG. Jamming a resistor in there to short out the sense pin is not a thing. These are pwm charging and have been for a while. Even after spending $100 on the OTG cable alone it's still not working.. rooting.. twrp.. none of It makes any difference at all

How do you even do that? An OTG adapter is < $5. A connector is < $1.
OTG adapters normally have the ID grounded right inside the connector so you can't use that unless you chop up the connector.
You need to make up your own micro USB connector.

I don't have a Samsung Tab A so there's only so much that I can say.
All devices have a linear or DC buck converter that feeds USB power to the battery.
All devices (that do powered OTG) have a charge pump or a DC boost converter that feeds power to the USB jack.
Both of these are under control of the processor.
Look in your kernel source under usb/otg
You should easily be able to see if you have an ADC on your OTG ID pin or if it's just a GPIO.
Look at your device under /sys and see if there is anything suspicious with "adc" in its name.
Code:
find /sys -name '*adc*' 2>/dev/null
In worst case you'd have to modify a driver.

Y otg cable (replaced 4 pin micro usb connector with 5 pin micro usb connector) + 68k + 20k gives fast charging and data commuincation on Galaxy Tab A 2016 (SM-T585)
