[Q] Please Help! USB OTG Not Working on Blackview Ultra A6 - Android Q&A, Help & Troubleshooting

So I tried using OTG devices with the Blackview Ultra with both the stock rom and CyanogenMod 12.1 installed but it just doesn't work. I have tried multiple USB OTG cables and none have worked, I know it is not the cable because it works fine with my friends phone. I have also run USB Host Diagnostics on the phone and it says that the OS supports OTG but simply no device is detected.
The bizarre thing is that the Ultra itself claims OTG support. It even comes with an OTG cable included in the box!
So if anyone could give me some insight on this it would be greatly appreciated. I really want to see some USB devices working with my phone. Thank you!

Bump

Anyone?

Heyho XDA,
sorry for pushing this old Thread,
but i have exactly the same Problem
Everytime i plug in a USB keyboard or a mice,
the Phone freezes instantly -.-
My Setup is:
CheckRom Revo v6
Siyah Kernel v2.6.13
Original Samsung OTG cable
Anyone else having this issue?
Or maybe a fix ?
Same problem
I've got the same problem. Pendrives, memorycardreader and systemcamera works great, but no mouse and keyboard.
Tested the same setup on my friends Galaxy Note and it worked out of the box. But not on my phone.
Download
USB Host Controller from the Play Store , see if that works.

It seems that USB Host and USB OTG are two different things. It has to be supported in the kernel. And I did root my phone and derooted by changing the kernel. I didn't save my original kernel so I had to download a new one. So maybe my kernel doesn't support OTG anymore.
I'm gonna look closer into this and report back it I'm getting it to work.

[Q] OTG strange problem

Hello all,
first of all, tried to use search of this problem, couldn't find anything.
So my problem is that when I connect to my GT-I9100 OTG cable with flash drive(8gb) it just dosen't detect it also tried using philz, apollo(dosen't remember corectly name) dosen't work either. Tried using OTG Troubleshooter it is question mark on "OTG Detected", with OTG cable everything is good because asked my friends to use it, they said that it worked for them. I thought it was my phone usb(where you put in) was damaged but no, phone is charging perfect also USB to PC works correctly. Also OTG cable holding very weak.
My rom:Neat rom(newest)
Kernel: Dorimanx(newest)
Thanks for help
Merry Christmas and happy new year
Regards, Paul.

Y type OTG/Power OTG for M4 aqua.

Well, we know that m4 aqua doesn't have native otg support. But is it going to detect usb devices connected via Y-type otg or power otg cable ??
I've seen some devices to work this way and also heard that it works for almost all devices. There are many devices out there with SD615 chipset and they have otg support.
so, the point is, has anyone tried it on m4 ?? is it going to work??
just making sure before buying a cable.
thanks.

Q1:
Have you tried connecting your device to the computer via a USB cable? Can the computer recognize it?
If no, maybe there is problem with your USB port.
If yes, proceed to the next question.
Q2:
Have you tried changing the connectivity state for the USB port in Settings?
If not, try it out now.
If yes, report back and we'll discuss further more.
Use Es File Explorer... That's what I've been using
Sorry for late reply, I got it working, I replaced the usb cable, I think that the quality of the cable was too bad

OTG Not Working

Hi all,
Recently i found that my One plus X does not support otg.
Here are the few things i tried.
*I tried connecting the same otg pendrive in other 2-3 mobiles and it was working fine.
*I tried connecting a different pendrive with the help of a otg cable to my oneplus x, but it did nt even detect it.
*Also one more thing, when i connect my Oneplus X to PC using the OnePlus X data cable, it was showing error like "USB device not recognized"
*Also tried connecting to other PC and Laptop but it gave the same error.
Currently I am using Resurrection Remix Rom latest version, but otg was working fine on it one week before also the connection to PC using data cable was fine. Now if I connect my device to PC using data cable it wont even show option on the notification to switch to MTP mode or camera mode or charging mode. It just charges my device.
The otg does not even work in TWRP mode. Previously it used to work fine. I even switched to official marshmallow rom provided by Oneplus and enabled the otg option from settings, but it did not work. Hence I switched back to resurrection remix rom.
Is anybody facing the same issue??
I guess my device has hardware issue regarding otg support now. Because it charges the phone but does not support otg
Does anyone has new suggestions that i can try? Or any help would be great.
Thanks in advance.
