Energy Supply by Usb hosting and Micro-Usb to HDMI Cable

Hi! I know there are several kernels that enables usb hosting on our Galaxy S, [I'm using last Semaphore right now], my question here is: Does exist any way to supply energy directly to the usb device from our terminal? I have the proper cable to connect them [atm I don't remember the name of it], so I thought "There is an exchange of energy trought the usb entrance in our phone, so why we couldn't use it not just as input, but as output too?" Let me know it, and thanks in advance

Because you can either have power or data transfer, not both, due too pin arrangement, external power is needed unfortunately

Thanks for answering! But let me understand, when usb mass storage is connected, is there not both transferring of data and power supply? Why would be different with usb hosting?

Up!

my bad actually, was thinking of situation when you have fast charge enabled....fact remains you need external power supply..Google it, plenty of info out there

I understand.. Well I googled it, but just couldn't find the reason. I guess it's like you said, just a hardware matter. Thank you!
Just a last thing, as we're here. What about the micro-usb to hdmi adapter? Is there the same problem or it will work?

Yes! Very thanks, let's hope so. At least I've given 5 free euros and not 15 to Amazon xD
When I'll test it, I'll post the result :good:

UPDATE: Apparently, neither the hdmi output cable works on i9000. I looked around, and I discovered the reason why it doesn't work is about mhl drivers. They need to be compile inside the kernel, and no one seems to have done it yet. Ufortunately, 2 on 2 failed. Damn and thanks either :good:

Up! Anyone could implement those drivers in a kernel? I can donate for that too! Come on!

Notification Panel/USB OTG

Does anyone have an idea what Amazon calls their status/notification panel? Like is it an APK? Is it tied into something else? I'm trying some things, but I haven't been able to track down it's source. I may have completely missed this one, but until I'm accused of being blind as a bat, I'm stumped!
I changed the title of the thread because I wanted to add another question to this when I posted it, but had forgotten what I wanted to post.
I have downloaded a few apps for both my phone and my Fire HD 8 that tell you if your device is USB OTG (On The Go) capable and if it's turned on. Both my phone and the tablet have USB OTG both are supposedly working. Question is: Does a USB OTG adapter work on the tablets? If so, what kind do I need? I see several types on Amazon and some have every connection under the moon. I don't want to waste the 5 dollars or less if it doesn't work.
I want to be able to use my phone to talk to my tablet and unless you jerry rig a standard USB cable (I tried and the biggest problem is getting the rubber and plastic off the micro USB plug), USB OTG cable is the only other way I know of.

Xbox One Controller - Bluetooth Connection Possible?

Hi everyone,
Was wondering if anyone was using their axon 7 with a wireless xbox one S controller over bluetooth, have you had issues connecting? Since apparently, the controller won't work when connected through an USB OTG cable...
Thanks,

I tested a PS4 controller via bluetooth and it worked, so maybe the xbone controller will? Can't you try?

I'm asking because I want to buy, so cannot try myself. But have already heard from other source that bluetooth connection is not possible on the phone due to microsoft firmware upgrade...

I know that exists, but I'd rather not buy something else, if I already have enough controllers at home.

Non Xone controller is not bluetooth. You need a specific adapter.

The Xbox One S Controller does support bluetooth, but apparently only for select android devices.
I'm now looking into the possibility of connecting it through an OTG adapter, see my other thread.

It might reboot because the controller attempts to charge from the phone. You should try with a powered OTG.

I'm curious, how much current does the HDD draw? Most full-size HDDs draw 5V 1A, don't know about 3.5 inchers but I've seen some with only one USB2.0 connector (500mA)

And yes, you would be correct ~1A, 5V.
But I can't seem to find powered USB C otg, in my country (cheaply )
Also I have put non chargeable Alkaline batteries in my controller.
Strange.
Additional Query -
Does USB C multi port adapter ala MacBook work with Axon 7?

Woah seriously? Because you're the first one I've found across XDA, Discord & Reddit that says that Xbox One S Bluetooth connection works... Are you running the latest Xbox One S Controller firmware? Also, which android version & rom are you working with?

Also, it's already confirmed that the Xbox One S controller only draws 500 mAh max from a usb port (see aida64 screenshot), so I've always found it to be pretty weird that the Axon 7 reboots on connect due to power draw...

Xbox one S updated with windows 10 anniversary edition. Maybe the latest version.
I have 3 different android devices on android Nougat 7.1, working with all of them.
1. Axon 7 2017 Chinese, 4gb 128gb - stock zte rom - ZTE_A2017V1.1.0B16
2. Xiaomi mi pad - LineageOS 14.1
3. Nvidia Shield TV - Shield Experience Upgrade 5.2
And buttons are mapped correctly too. I have played some games and ppsspp with it.

Do you remember updating your controller's firmware either through the Xbox accessories app or on the actual Xbox One Console?
Thanks in advance for responding btw .

Hi,
I tried taking kmsg(kernel log) when connecting xbox one s controller to Axon 7.
But I was unable to.
There is no /proc/last_kmsg
And bugreport is not being collected for reboot.
And I cant access /data/tombstones
Additionally dmesg in non blocking on android. So cant take kernel logs when the system reboots.
Any suggestions?

Normally, the phone does not reboot anymore if you have a nougat rom installed, when you connect the controller. Or at least, that's what's mentioned in this thread.
I don't know if you're on a nougat rom or not...

Hi,
I am on Nougat Rom, as mentioned previously.
Initial support for wired xbox one (S) controller was added to xpad kernel driver in linux kernel 3.17.
Chinese Axon 7 Nougat B16 has kernel version 3.18.31 (dunno about USA or Euro versions),
So I theorize that restarts are being caused by kernel panic due to driver problems, but I am unable to check.
I any case xbox one S controller wired OTG is not possible without custom kernel(maybe?) on last years devices, as most of them are on 3.10.
Maybe wait for Google Pixel ).
Regards,
Ravi

[Q] Charging in USB-C OTG-host mode

Hi guys,
I am using a pass through-powered USB-C hub through which I am using external USB devices (keyboard and mouse), as well as a larger monitor for screen mirroring. This works reasonably well. However, the USB-C hub, while powering the external devices, does not charge the phone while it is in OTG host mode (which is needs to be in order for the external devices to work). This leads to the problem that the phone is slowly draining when external devices are used to play games, work on spreadsheets, or whatever. So, I was wondering why this is and found that OTG host mode charging seems to be restricted by the kernel. Very annoying!
Looking around I found that there are custom kernels for other phones that tackle this problem (examples here (OnePlus One) or here (for Xperia Z5 compact)). Which leads me tot he question: is there any known solution for this problem for the OnePlus5? Is there a custom kernel supporting charging in OTG host mode? Is there any other work-around that would allow me to power my device while using OTG?
Thanks!
PS: My device is rooted but is otherwise running on stock kernel and ROM.

Nope and it won't, I have a thread in the themes and apps section about targus display docks as after much research I found that it is the only way to reliably mirror your screen in real time with no latency issues, with that being said there is no charging whilst this is in use, I wish there was but there isn't.
It's possible I suppose that power could flow both ways but after all the time that I've spent looking, I'm yet to find it.
I've tried over 10 docks, splitters, dual output cables. Devices with power input, none have charged the device.
I think the nature of the way display link works it just doesn't allow it.

Yeah, I saw your thread. In fact, I was just about to post in there another - much cheaper - device I'm using for reliable mirroring.
Edit: actually I posted it in the 'usb-c to HDMI adapter'-thread, in which you were also quite active.

Yeah, it is definitely possible (see the threads I've linked). But it depends the kernel allowing it, from what I understand. Anyways, if nobody has come up with a kernel allowing for it, then it won't happen I guess.

With displaylink technology it's not possible.. with previous hardware ie the HTC 10 it was but only with standard usb to hdmi converters, displaylink doesn't allow it.
In regards to usb OTG cables, I've never tried.

Oh.. so then there is a second limitation based on DisplayLink. Aside of the kernel.
Well. Luckily the OP5 has great battery life. A few hours of activity is no problem. Especially since I run everything through a USB-hub with its own power source anyway.

From my tests I've found the hub being powered makes no difference to the drain of the battery on the phone..
The OnePlus has got amazing battery life, definitely something I need in my life for my next device..
In regards to charging whilst using a displaylink honestly my comment is based on the testing of around 20 different devices and none of them allow charging, if it exists I personally haven't come across it.
A shame but not the end of the world..

Lava - Simulcharge
For what it's worth, I had a difficult time finding a device which supports simultaneous host charging as well. As it turns out, there is a device called the Simulcharge from Lava Computer that works quite well on Samsung tablets. I'm not sure if it will work with other Android devices: (unable to post link - search amazon).
It's a bit expensive but it works great!

Is there a cheap displaylink that works with the OP5 that also has a USB port for peripherals?

Sorry to revive this thread from the dead, but I'm also looking for a way to connect both charger + USB-OTG at the same time. I have a USB C hub that's capable of that, it works perfectly fine on my Oneplus 7. However on the OP5 it's either OTG or charging.
Did you ever found a way?

Does OTG webcam work on the Oneplus 8 pro?

Hi guys, long time Android enthusiast.
I would like to enquire if anyone knows if the Oneplus 8 pro has the required v4l2 drivers to support OTG webcams. Software support is finicky between manufacturers (some just didn't implement it)
Could someone help me test? You can try out with a otg type c and this app:

Tried my USB-borescope (camera with a flexible tube and led lights) with OTG cable and it works just fine
Edit.. no idea about the sound tho, since that camera doesn't have any mic.

Aarrgghh. I need an adapter to make my old device connect to the new phone...
