USB OTG+Charging simultaneously - Xiaomi Mi Pad 4 Questions & Answers

Does the Mi Pad 4 support OTG+Charging at the same time? So if hook up a Y USB Type-C cable, connect power, connect a usb storage stick and plug it in the tablet. Are you able to charge and use the usb stick simultaneously?
Because I am looking to replace my Nexus 7 (2013) for my in-dash car install with the Mi Pad 4 (dimensions are almost identical) this would be a nice feature
Regards,
Frank

did you find a replacement?

I'm in the process of doing something similar with the Mi Pad 4. Waiting for one USB OTG hub which supposedly supports charging and data at the same time. will update when it comes and I test it.

Glad to hear! I'm waiting to buy it. Probably will as soon as you say it works, though. Thanks for sharing, in advance!

Still waiting for mine. I hope that it will be soon but we are still talking about "China Air Mail" so...

Update: I got my HUB and unfortunately it does not charge the tablet. Only usb ports are working. The more interesting part is that on my phone (Huawei Mate 20 X) it is the complete opposite... It charges the phone but the usb devices are not detected...
I'm beginning to think they should remove the "U" from USB when it is about Type-C ...
I also am thinking that the tablet does not support the USB PD protocol and there might not be any hub that will do charge and data on it.

Hey guys,
Success!! .... or at least 99% of one...
Some weeks ago when I tested the first hub I purchased (the one that worked as a hub but not charging) I contacted the seller and the replied to me that they have most probably sent me the wrong model and will send a new one. Today I got that replacement and upon opening the package I was quite skeptical to find the same (at least visually) hub. Anyway I tested it and oh miracle! It is charging the tablet and at the same time it works as a USB OTG HUB!! The only caveat is that it is charging slowly (about 200mA to 500mA) but at least it is working.
This is the one: LINK

anyupdates? thinking of getting of these to replace my n7

This is great.
1. Can you confirm which ROM and kernel you were using when the OTG+Charging was working?
2. Where you able to test a USB DAC as an OTG device simultaneously when charging?
3. Any specific order in which the peripherals, tablet and charging cable have to be connected, in order for OTG+Charging to work?

1. Unfortunately I don't have the tablet anymore as my project didn't happen but I'm almost sure that it was either the Xiaomi dev ROM or the Xiaomi.EU rom. (it was a MIUI ROM and I have not tested any other MIUI ROMs than those two) Regarding the kernel, it was which ever Kernel was in the ROMs.
2. DAC I did not test. Only USB Flash drive.
3. Order I tried first connecting everything to the hub and then the hub to the tablet, and also connecting and disconnecting USB Flash drives while everything is connected.

Thank you. It did not work with MIUI or XIAOMI.EU ROM for me, but it does with the Havoc ROM. USB DAC + Flash Drive were both working plus the Pad was charging as well (upto 750mA)

OTG

On my Le Max2 OTG does not work .... and in your?
How can I fix the problem?
I didn't have a device to try that, but I tried connecting a gamepad via bluetooth and tried to listen my music via bluetooth (Car-Media-Device was the output). Neither of them worked.
Bluetooth working fine on 14S ROM. A little slow to connect but I have connected 4 items and all work fine @massymoroboshi OTG is also very good, I think its fast too.
I have used USB type c drive and it just asks to allow
For computer make sure 1 drivers are installed an 2 select media device from dialogue box the phone opens when you connect
ok thanks .. I have tried with an adapter micro-USB / USB-type-C + OTG cable, and is not detected by the phone. The PC connection is ok, I'll try to buy an original OTG cable

Im on 14s right now. Still USB otg not working. What am i doing wrong
Hi there!
I Think I've got full information on the OTG matter now after googling and testing stuff.
tldr; Get a USB (3.0?) Type C OTG Adapter, it will work.
Longer version:
After getting my USB C to micro usb adapter I tried getting my USB Sticks to work, no luck, not even blinking so I guess not even power get to those things like this. Then I started googling to find out that the same issues were already persistent with older LeTv phones.
Then I went out to buy a USB C 3.0 OTG Adapter (cost me ~7 bucks in Saturn in Germany, will be cheaper to have online for sure), got my sticks to work and even my 2,5" External HDD without any hiccups. ROM I'm on is 14S, not on the newest update.
I will attach a pic of my adapter so at least you know of one that is confirmed to work.

Jeah I also got it working. Bought a type c Adapter on Amazon for 3€. Pretty stable for stick and 2,5"drive (drives first startup is Pretty long, about a minute) . But there is currently no support for game Controllers via otg neither via Bluetooth
Successfully connected and paired the PS4-Controller via SixaxisPairTool on my Le Max 2. Now I can finally play games without a problem with my PS4-Pad

USB OTG not working

Hello there,
unfortunately, I couldn't get USB OTG working, even though it should support it according to various spec pages.
My setup is following: LG G5 <-> USB Type C to Micro USB adapter <-> Micro USB-OTG adapter (2.0) <-> USB 2.0 thumb drive (see attached picture)
The light of the drive is not lighting up. So maybe the G5 isn't powering the device?
I've tried three different USB-OTG adapters without success. All three are working on a G4 as well as on a Nexus 7 (2012) flawlessly.
The USB Type C to Micro USB adapters should work as well. Charging (normal and QuickCharge) is working perfectly fine, even ADB does as it should so the data pins should be connected. However, both adapters lack D+ and D- pins for USB 2.0 on one side. This should not be a problem, though. (see attached picture)
Did somebody succeed in using OTG in a similar setup?
The usb c to micro adapter is your problem

Is it because the USB controller needs to be configured to be in OTG-mode by using another resistor value?

Do you know whether they comply with the USB 3.1 specifications?
I have the same issue so i used the usb type c to micro adapter on an usb cable and it connected to my computer just fine and i could transfer data is it still the the adapter?
You do know they have started releasing type c OTG cables and adapters without the need of converting from micro usb to type c, right?
See the pictures below. These are just some of the types you can get, soon enough there will be more types of otg and more adapters for type c usb
If not then see the links provided
According to their titles, it says that they comply with 3.1 specs..

Thank you for your reply .
I am aware of those adapters, I just hoped I would be able to use my OTG adapters I already had at home. I'll try to buy one later that year and will report back which one's working…
Hello, sorry for my english, i'm from germany! But i have found the problem, why you can't connect to the usb storage! If I disconnect my sd card in the settings and connect my otg device, i can find the usb stick! My lg g5 can only connect one device in time!
Not the adapter ...
I was on lineage OS until end of May and did not get the OTG working with any adapter what so ever.
OTG worked with the Stock Kernel and now I am running Resurrection Remix' version of April 8th 2017. Since Resurrection Remix is based on lineageos - as expected - the OTG got broken in later Resurrection Remix releases.
So something weird happened in the firmware between April 8th and now.
This one works perfectly.

Any news on LG G5 and broken OTG?
i have the same issue, i can connect my G5 with Adapters to my PC... there Data Transfer is working
But no usbstick or usb led or usb mouse is running with choetech or anker usb adapters.
i also tried this one

Tried many adapters that claim to be h850-OTG-comaptible (have now 8 of those). It can't just be the adapter, because earlier version of Lineage OS and RR worked and still work.
But I am glad that you have found a solution for yourself

I've already poked our G5 maintainer about it and he'll investigate the issue when he gets back from vacation in a bit over 2 weeks. It has to be something that LOS changed upstream and he'll try to work it out when he gets back
The same issue here. When I first time connected OTG adapter G5 showed notification about charging and when I clicked that it could be changed to multimedia device or something similar. It connected the USB key successfully but disconnected few seconds later. Never ever got this notification again when connected any other USB keys. Nowhere in the settings can be found any USB options.. Any idea how to fix this?
I have the same issue.
I have a number of usb c otg adapters and devices. Like cameras (endoscope). Drone telemetry receiver. Programmable LED spinner that uses an android app.
All of these things worked in the past. Connecting to my LG G5 resulted in a popup where I would choose which app to run.
Now when I plug anything into the usb port using an otg configuration, nothing pops up. Nothing happens.
Phone still charging ok via usb.
Hello all
I finally gave up on OTG, after having bought 8 so-called LG G5 compatible OTG adapters for half a fortune
BUT for everybody who is in the same big despare as I was, I - by chance - finally found a great solution for myself.
"SanDisk Connect Wireless Stick" with integrated WiFi (mine has 32 GB), provides copying, streaming and whatsoever to your phone - simple and simply genius.
see also:
https://www.sandisk.co.uk/home/mobile-device-storage/connect-wireless-stick
https://play.google.com/store/apps/details?id=com.sandisk.connect
Plug it into the PC and use it like a normal USB stick and connect to Phone via WiFi and optionally share with other mobile devices.
For home internet you can even use the stick and WiFi at the same time. Whoever invented this gimmik may have been aware of all our issues.
Just works like a charm. Unbelievable!
Instead of waiting "til kingdom come", stop posting, complaining, waiting - at least I will stop, because obviously nothing's going on in this direction.
A little Addition: when you have IP-config (or similar) installed on your LG G5 and you open IP-config
https://play.google.com/store/apps/details?id=com.paksoftwares.ipconfig&hl=en
then connect the WiFi of the PC to the SanDisk Stick and type the gateway-address shown in IP-config into the URL-line of your browser
You can then transfer data between phone and PC directly via the SanDisk Connect WiFi stick ... how cool is that?
Mine works fine. Had issues with certain kernels though...
Bump
Still same Problem in RR.
The Adapter works in TWRP version 3.1.0.0 but in the newer versions also not.
I don't even get a pupup and devices Art n't powered...
Is the typhon kernel capable oft handling otg?
my experience
I am using the stock Android OS 8 on an LG G5 from Fido in Canada, specifically the “LGE LG-H831” variant according to the Google Play Store. I have a microUSB plug↔full-size USB Type A socket USB OTG adapter from StarTech that works with my Samsung Galaxy Note 3 but I needed a USB Type C plug↔full-size USB Type A socket USB OTG adapter now that I have switched from the Galaxy Note 3 to the LG G5. I bought five of this model of adapter (in red colour) on eBay for only around 5 CAD total including shipping from Asia to Metro Vancouver, Canada, which took between 20 and 30 days but buying this type of product on eBay from Asia cost way less than buying it locally:
https://www.ebay.ca/itm/283235483653
Sorry, I got ahead of myself in writing my story because I am tired and I did this USB OTG stuff at least a week or two ago by now. I have two models of microUSB socket↔USB Type C plug adapters, one black one from StarTech and one white unbranded one that may have been included with the LG G5 but I do not know for certain because my father gave me this LG G5; I am not the original recipient/user of this LG G5. I could not get any of the USB devices I tried working with the LG G5 with these two types of adapters connected together. I tried with a USB SSD, a USB keyboard with a microUSB connector (so actually using only one adapter in this case), a USB keyboard with a normal full-size USB Type A plug, and a USB↔Ethernet adapter. That is why I searched the Internet and found this topic. Then the adapters I linked above arrived. With the adapter I linked above, all of the USB devices that did not work (other than the keyboard with the microUSB connector) now seem to work with the LG G5. I was not able to network the LG G5 via Ethernet in the time I had available to spend on that project but I think this was only a software problem because the hardware seemed to be working. When I say the USB devices did not work with the LG G5 with the old adapters, I mean nothing seemed to happen when I connected the USB devices to the LG G5 using the old adapters. With the new adapter, the USB devices seem to work when connected to the LG G5 without any special action. I upgraded the stock OS on the LG G5 from Android OS 7 to Android OS 8 before I began seriously using the LG G5 because I did not want to lose the time customising the software if the in-place upgrade of the OS failed. Almost all of my experience with the LG G5 is with the stock Android OS 8, not Android OS 7 nor earlier versions. I have not and will not try to replace the stock OS on the LG G5 because I had a bad experience with replacing the OS on the Galaxy Note 3 even after I reverted to the stock OS. My LG G5 seems to still be unrooted, which seems to not matter in practice for my use case so far.
I purchased a USB 3.1 docking station model T3527-VIII+ from ineo on Amazon. USB 3 to type C adapter comes with it. I use the adapter with my LG G5 RS988 without a problem. Devices are: regular USB drives, USB keyboards and USB mice.

Does xiaomi Redmi 5 phone support OTG?

I noticed when I plugged my OTG cable in the xiaomi Redmi 5 phone, and connected my usb mouse to it, the phone does not recognise it.
This is not an issue with another phone I have. The above setup works fine in my Moto g play 4.
Just wanted to ask community if this is the case or fact with the Redmi 5 phones, or, is there a specific OTG cable I need to buy?
Yes bro, obviously
I used the old OTG that I used for my Nexus, it worked although I didn't try to put a mouse, for flash drives, it definitely works
Yeah, okay. Tried one more time and it actually worked...
It Does work. . U need to buy original Samsung otg cable which is best in quality available in India. If it doesn't work plz turn on developer mode and turn on usb debugging. .
Yes

Otg + charging

Does out tablet support otg and charging at the same time?
Tried by using hootoo ht-u001 type c adapter and a sd card, otg is disabled once the charger is plugged in.

Do you have a native firmware MIUI?
You can experiment, first connect the charging going to the hub, and then the periphery of the USB flash drive or keyboard and mouse..
and then vice versa, first the periphery and then the power to the hub
on my tablet with micro us it mattered... Can you try different variants
I guess you will need something like the one in the link below that supports USB Power Delivery.
https://www.aliexpress.com/item/USB...469.html?spm=a2g0s.9042311.0.0.3b144c4dDoroZN
It is mainly for Macbooks but it is compatible (according to the sellers) with most Smartphones and Tablets that use USB Type-C.
I just ordered one for a project so I'll know in several weeks (when it arrives from China) if it works with the Mi Pad 4.
Update: I've just checked the hub you used and it is also with USB Power Delivery... oh well let's see if I'll get lucky or...
anyone have success with this? i have a few adapters and hubs that work with everything else but not the pad 4.

USB C to A OTG causing a weird bug on my Tab S6

I'm trying to connect my Tab S6 (SM-T867V) to my Logitech mouse, but as soon as I connect the OTG cable to the Tab, even before the mouse controller is insterted, I get a notification that says USB connector connected and then it switches to USB connector disconected and just keeps flipping between the two notifications every few seconds seemingly endlessly. I tried the otg cable with my Note 9 (SM-N960U) and it works perfectly fine with my mouse. The Tab and Note prompt me with charging/file transfer when the otg cable is hooked into the Note and connected to the Tab via a usb c cable so that seemed to work fine. The tab also works normally when charging and using a usb c to hdmi adapter, so I don't think it's a port issue. Both devices are on One UI 2.1 and both have USB 3.1 type C 1.0 reversible connectors, so I'm really confused as to why I'm getting this bug. If anyone has a solution, I would greatly appreciate it!

I didn't think about PD making a difference, but maybe you're right. My usb c to hdmi does support PD, but the power wasn't plugged in when I tried it and it still worked tho ?
But either way, I ended up purchasing a bluetooth mouse instead just because it's more useful to have one for my tablet rather than unplugging my laptop's every time I take the tab somewhere. I will keep this in mind for if I need to add more accessories later, so thanks for the info.
