I want use the LG V30 as a streaming audio device and connect it to my HiFi setup via external DAC - audiolabs mini M-DAC.
This DAC has an PC/Android OTG micro USB port for connectivity and also a built in battery for optional portable use. I leave the DAC plugged into power and don’t use it as a portable device.
When I connect the V30 to the audiolabs mini M-DAC using a standard USB-C to micro USB cable the phone goes into USB “Power Supply” connection mode. Although the audio works fine with the DAC using the USB Audio Player Pro app it rapidly depletes the phone battery.
I have tried to manually switch the USB connection mode to “Charging” and others but it just reverts back to “Power Supply” connection mode.
Can anyone help figure this out ?
I don’t think this issue is limited to V30 phone and no one in the V30 thread has been able help with it. For this reason I’m trying the general QA.
I’m guessing the issue is to do 2 way charging offered by USB-C port. Ideally I would like the phone to be able connect to the DAC and draw power from it or at least remain passive.
My phone is Rooted if that helps.

I have no issue getting my Chord Mojo working with the UAPP app on my S8+ but when I try to use band camp, youtube or any other apps it will not route audio to the DAC properly. Note that UAPP uses a proprietary driver for routing data to the extetnal DAC. A notification comes up when connection Mojo to S8+ via micro usb-usb c otg cable(see screenshot below)
I have tried every option in the normal settinsg and developer mode but no matter what it just reverts back to "charge connected device". I have played around with all the USB settings in Developed mode;
Prevent automatic usb routing
Setting the usb device to audio source,
/MTP
Etc
Nothing works.
I even uninstalled UAPP, attached Mojo and opened band camp, still nothing. Worse yet, often it will freeze with Mojo connected and then restart itself or get stuck on the carrier boot screen during restart.
Seems that Android system is not allowing the device to connect properly although I can't be sure. I just want to be able to send all my audio to my exceptional Chord Mojo. Bummer because everything worked fine on S7 Edge running Android 7.0 when I selected MTP under developer options. Unless there's a fix I'll only be able to use Mojo with UAPP.
Im having very similar problem on S8, got an OPPO HA2 DAC, have bought a micro USB to USB C cable, and the phone is charging the DAC? It doesnt let me change the output as per your screen shot above.
Can anyone help?
I've ordered the meenova c to b otg cable, will report back.
i use andoird4viper with my DFR and it works. just had to lock the effect to headset and it should work system wide, as least for my case.
The meenova off cable made no difference with regard to getting Mojo to work with apps other than UAPP.

I'm not rooted and don't want to root.
Still no fix in sight but it is definitely a software issue and most likely with Android system processes.
Could some one please suggest a way in which I can avoid running down the phone's battery when accessing the internet via a hard wired connection into the USB micro port of my mobile phone?
Do you think this would work?

For this purpose I do not want to access the internet on the phone by wireless.

I have tried:
IA micro to usb adapter: Plugable: Model USB2-OTGE100. It does not have a power supply and uses my phone's battery to power the adapter.
A Micro-B usb hub that has 3 standard usb outputs and one power input. It also has a Charge to OTG switch and it does not do what I want as it does not charge the phone at the same time as browsing the internet.
I got an Anker OTG hub. It works completely if I connect it to my laptop, however, if I try connecting it to my phone, my USB mouse+keyboard combo (wireless with a receiver) doesn't work. It works with other devices, including my laptop's USB C port, and my old phone's USB C port.
I did turn OTG on prior to connecting anything (I'd love (root) to know to keep it on at all times).
I already ensured they work on other computers through that OTG adaptor, and that a USB storage stick works on this phone through it. In addition to that, HDMI works too (the adaptor also has an HDMI port), and the USB C passthrough passes power successfully, as well. No warp charging, but that is to be expected and that's alright.
I have TWRP and everything. Is there a kernel mod I need? I'd be happy to do whatever's needed.
Maybe OnePlus needs some updates
Even i have latency issus with my midi keyboard
But not with op5t
Verizon Pixel 4a running Android 11
I have a powered hub that uses a 5V 3.6 power adapter. There are three devices connected to the hub via USB A connectors - midi keyboard, audio interface and midi controller. If the hub is connected to power and I plug the OTG cable in the Pixel 4a goes into charging mode and the devices connected don't communicate via USB. If I disconnect the hub's power adapter and then plug in the OTG cable the devices communicate. The draw at the point with the screen on according to Ampere is 550mah. If I then plug in the power adapter it drops to about 180mah with the screen set to lower brightness.
I have two questions regarding this setup:
1. Is there any way to have USB communication and charge the phone at the same time?
2. Is there a way to programmatically control whether the phone is charging or communicating over OTG using an app or Tasker?
Thanks,
My Samsung S9 has had some screen damage and the touchscreen mostly does not work.
In order to navigate it I must use a mouse that I connect to the phone using the supplied USB C- A adapter.
I wish to get my phone repaired but I wish to backup all the data upon it first.
If I plug my phone directly into my PC, it asks for my permission to allow the PC access. However, since the touchscreen does not work properly, I cannot press the button to accept.
I could not plug both the mouse and PC simultaneously.
So I bought a USB-C hub. (Actually I've bought several, none of them have worked, this latest one is the most expensive and I had hoped it would work - (https://www.amazon.co.uk/gp/product/B07ZVKTP53/ref=ppx_yo_dt_b_asin_title_o03_s00?ie=UTF8&psc=1).
It has a separate port for USB-C Power Delivery and a separate one for data.
I plug the attached USB-C cable from the hub into my phone, and then I plug my mouse into a regular USB port, my charger into the USB-C PD port, and another USB-C to A cable from the USB-C Data port on the hub into a USB port at the back of my (new) PC.
Now my computer does not recognise my phone at all, nor does my phone seem to acknowledge it is connected to a PC. The mouse still works upon the phone and it charges fine through the PD port. If I plug the phone straight into the PC, it is recognised, so I do not think the problem lies there. The hub seems to block communication between the phone and PC.
I would like to backup my data and get my phone repaired. If anyone can solve the USB-C Hub issue or propose another solution to my problem then I would be grateful.
A mouse and keyboard will take priority over anything else in a hub.
I'm betting the hub's power is 2000mA or 2.0 Amps.
What does your fone charger state its power is? Add the mouse, keyboard, and fone's milliamps together. If it's more than the hub's power pack supplies....
In this situation, I would use Vysor, this will defo solve your problem, it allows you work with your fone on your pc/lappy by providing a lovely window that is a duplicate of your fone screen, you'll be glad you found this!!!
I can provide an old cracked version I used for my emergencies, if there is no objections?
Then you'll only need the mouse to use as your finger
Google Vysor. case closed lol.

Hi
Thanks for your reply
It's not a battery hub, but just a USB-C hub (check the link). Power comes from the PD USB-C port which is hooked up to my phone's original USB-C charger.
It also fails to work even when a mouse isn't attached to it.
I will look into Vysor. Also thought about the possibility of using a standalone bluetooth mouse which would free up the cable.
Your fone will suck the life out of a poorly powered hub, by using vysor, your pc/lappy mouse will work your fone using vysor, best app I've ever seen for working with broken screens, just plug phone direct into lappy, vysor works if you've no screen at all!!!!!
Use
Vysor

Dont pay for mouses/hubs in this scenario. Just pay for a top quality tool. I would place this as my number one android tool for ANY fone.
Again, if all your doing is data recovery (saving your stuff) I have a patch for an earlier version to unlock full version I swear by, you could use this once if only to try before you buy
The hub supports 85W fast charging directly from mains, which is what it is getting.
How do I enable USB debugging specifically for the app?
I have enabled it in developer options but when I connect my phone via USB to my computer as per the Vysor app, another window pops up on my phone asking to allow USB debugging. Ask there is no mouse attached to the phone at this point, I am unable to allow it.
