[Q] USB OTG on CM12

I am using Oneplus one smartphone and flashed CM12 a couple of days ago. I cant use the USB OTG option properly. Updated to 31st Jan build and still go the issue. I am rooted and hence used a couple of softwares like Stickmount, USB OTG Helper and all and none of them solved my issue.
The exact problem is like this.
1. Can mount a USB but wont show in setting->Storage
2. Can access with a file manager.
3. Wont thus be able to unmount as there is no option at all like there was in 4.4.4 kitkat.
4. Even if you unplug it will give a message saying usb was not removed properly kinda.
5. After an instance this wont detect any usb and to do that you have to restart the phone.
HELP PLEASE!!!

USB otg helper has an unmount option, so once you're finished just open that app and hit unmount. The fact that it doesn't show up properly in Settings/Storage shouldn't really matter as long as you can access it with a file manager.

But USB otg helper keeps on crashing for both mounting and unmounting. Without a proper unmount the device won't recognise another instance in this case.

Yeah, we know it's broken... it has been mentioned 1000 times this is broken in Marshmallow just like it was before the last Lollipop update, just have to wait for Moto to fix it.
There was one post where someone said they got it working in ES File Explorer and an external powered hub, something like you connect it with power, then disconnect power and connect the flash drive or something like that, but most people couldn't duplicate it. Google might help.

Nice... the US version does not work.

XT 1543, the Brazilian version does not work too.

Just to update my experience, today I updated from the last soak to the release Marshmallow on my XT1540. OTG works fine and I'm able to connect to my SanDisk 32GB flash drive. I've never had a problem with OTG in Marshmallow.

Otg funtionality....

So i got a bunch of on the go cables. And wanted to see what the stylus could do.
So far ive hooked a 160 gb otg hard drive. Works decently.
2. Ps3 control for gaming.
3 flash drives. Of coarse this works.
4. Usb ob2 interface for scanning automobile ecus. Works better than g4 if i might add.
5. A old logitech wingman joystick. Works on some flight simulators.
I also ordered a while back a fastboot cable for my kindle. When i plug in on ms631 from power off no commands needed boots straight to fastboot mode
Im gonna make a pair of vr goggles prob this weekend and see if this screens good enough for vr. Did it on my g3 and g4. And it was killer

How did you get you're OTG to function? I plug in a 8gb flash drive to mines and it doesn't work for me I'm using the T-Mobile version MM.

Nothing its reading natively. Try stick mount.
Ive been reading about loads of people haveing problems with it im looking for a fix.
But the phone most def supports otg verriefied from more than one site

Has anyone figured out how to get OTG to work on the T-mobile LG G Stylo with Marshmallow? Mine has the latest stock 20c software (H63120c). I use OTG with my FLIR One Android, my SDRPlay, and my RTL-SDR stick, and it would be sad if I have to still use my old Xperia Z for all that.

This page seems to say that adding the file android.hardware.usb.host.xml to /system/etc/permissions will enable USB host mode. Has anyone tried adding this file to a T-Mobile or Metro PCS Marshmallow phone? I haven't rooted my T-mobile Marshmallow phone yet, but I will if I root access will allow me to enable OTG.
http://rfexplorer.com/usb-host-mode/
Update: Has anyone with T-mobile or MetroPCS Marshmallow and root tried this app, or manually making the changes that this app applies, to see if it will get OTG to work: https://play.google.com/store/apps/details?id=org.tauruslabs.usbhostcheck

So i was able to get OTG support enabled on the device but the phone doesnt send enough power to the micro usb so you would need an otg y cable to add external power supply like a portable battery

I haven't rooted mine yet, but I might now that it might be possible to enable OTG.

I gave up, and got a used "mint" LG V20 for cheap, which has OTG support built in. My LG G Stylo will be used by someone who has no idea what OTG is.

Besides "usb.host" to your permissions xml's, setprop "sys.usb.configfs=1" & "sys.usb.config=*" in dev options must be set right. Init.qcom.usb.rc told me what I needed to get mtp & adb working together.

[Completed] Weird Problem with OTG

I currently have 2 external hd I use for OTG, 3tb Passport Ultra and a 4tb Passport, both formatted to exFat. At first, the 4tb works like a charm. Suddenly, got an error from it from my android tablet that it was damaged and needs to be reformatted. Plugged it into my computer and my computer recognized it and its contents so i rand chkdsk and found no errors. When I tried it again on my tablet, it displayed the same error so I opted to format it again to exFat and copy some videos on it and tested it on my tablet. Unfortunately I ran into the same error. Basically my tablet cant recognize this external HD anymore without help of stickmount on exfat or paragon on ntfs. My other hd still works even though I reformatted it again and my tablet seems to recognize it without a problem. Has anyone come across something like this before?

Hi !
Please give us more info about your tablet , model / android version/ software status ( rooted , unblocked bootloader , mods installed ) in order to provide assistance , thank you
Cheers !

My tablet is a Galaxy Tab S2 (T-810) 5.1.1. stock root.
I feel that the problem lies with the external hd instead. All my android device sees it as corrupted but it works with no problem with Windows. I can only mount it with stickmount and paragon.

I don`t know how it worked at first , 4TB hdd needs lot of power to work on a Samsung device , you may need a Y cable
If stickmount does the trick then keep on using it , it may be software related , maybe an updated application did something
I may suggest to reflash the stock firmware and try on a clean system but a 4TB hdd it looks too much for a tablet

I use a y cable on it. The thing is, it used to worked before. One day it suddenly said that I need to reformat it again. I have another external hd (3tb) and it works no problem. I think something happened on the hard drive itself.

It could be a connector problem as well, a shortcut or something

I guess yes , the version is correct so it is for your device

[APP][TOOL] Lenovo Mobile Assistant for Moto E LTE Surnia

Lenovo Mobile Assistant
v1.4.1.14199 (Windows 7, 8.x & 10)
For Motorola Moto E 2015 Surnia/Otus​
DESCRIPTION:
The Lenovo Mobile Assistant is a Windows compatible application which allows syncing between your phone and PC for tasks such as:
* Making a backup of your phone's music, videos, photos, etc., from your PC and restoring the backup from PC;
* Managing your SMS messages and contacts from your PC;
* Managing installed user applications from your PC;
* Capturing & managing screenshots of your phone's display in real time from your PC.
In appearance and functionality, the Mobile Assistant is closely akin to Hi-Suite for Huawei devices. It features a simple, user-friendly interface as well as auto-updates when a new version becomes available. While typically an OEM application released with Lenovo tablets & ThinkPad devices, the Mobile Assistant works on the Moto E 2015 and a number of other Motorola smartphones.
INSTRUCTIONS:
Download the installation package from the link below and install it on your Windows laptop or PC by double clicking the MobileAssistant_Setup.exe file. After installation, connect your device to your PC via micro USB to USB data sync cable. Ensure USB Debugging is enabled and follow any prompts on your phone for sync authorization. Syncing should occur within 30 seconds or so.

Note: I just fixed the link on this post. For some reason, link sharing on the files was not turned on by default. Sorry for any difficulties caused by this. It should now be fixed.

Any members using this Windows based tool, user experience and input would be greatly appreciated. Any bugs, problems syncing, etc., should be listed on this thread, as well as positive experiences. Thanks

@MotoJunkie01 Tried it today..... The pc software seems to crash after I connect my phone. As soon as it says test app, it closes. Here is the pic.
I tested this on my otus(xt1506).
Also it'd be good if you could add otus to the title, as first I thought this software was only for surnia.
Anyways thanks for the software....

I've only tested it on Surnia, and even though the software undoubtedly works on many other Motorola/Lenovo devices, I can't confirm it's functionality on Otus. Thanks for your feedback. Ensure you have installed the latest Motorola Device Manager on your PC (to ensure latest USB device driver installation), try reinstalling the Assistant, etc., and let me know if you have any luck with it.
P.S. I've temporarily removed "Otus" from the heading until I can confirm functionality. If you get it working on your xt1506 I will definitely add Otus to both the title and heading. Thanks again for testing.

There is only one reliable driver source for Motorola devices: the Motorola Device Manager directly from Motorola's website.
Here's the link to the latest version.
https://motorola-global-portal.custhelp.com/app/answers/prod_detail/a_id/79106/p/30,75,27,
Download and install this software on your PC, and ensure you have USB Debugging enabled in Developer Options.
The Mobile Assistant app was pulled from a Lenovo Tab 3, so the problem may be your USB device drivers. I've tried the Assistant on the Moto G3 and Moto G4 as well with no problems. Keep me updated. Thanks.

Also, just a thought, but try changing USB cables and/or your USB port. If this doesn't work, download the Assistant again and uninstall/reinstall.

For any members who have used this application on a device other than the Surnia, please provide confirmation on other compatible devices. Thanks.

I also have this installed on my PC. The Official Lenovo USB drivers for Windows. While these drivers are intended for Lenovo tablets, maybe install them and see if you have any luck with Otus.

Here is a mirror link for the Lenovo USB device drivers. https://drive.google.com/file/d/0B1Sfod4HWfk2aUNVN2F3SUowLWM/view?usp=drivesdk. Definitely try these drivers. I've confirmed full functionality on Moto E 2015 Otus. I just verified that this link is stable as well.

Out of curiosity, when you downloaded the installation package, did you download all the files, put all files in a folder, and install the exe file from that directory?

Odd indeed. I have tried it on several Moto/Lenovo devices and, thus far, I haven't came across a device which fails to work on the Mobile Assistant. Have you tried revoking USB Debugging Authorization in Dev Options, and reauthorizing?
