Hi,
USB OTG functionality has stopped working on my 3T.
I was on OOS 4.1.6 when it was working.
Then i moved to Open Beta 10. After that it had stopped working,
Here is what i have tried so far :
Considering it a bug of open beta, i moved back to OOS 4.1.6. But to my shock, it was still not working.
I finally decided to root the device and explore the apps that claim to mount USB (requiring root permissions)
After successfully rooting the device and installing TWRP, i installed ExperienceOS based on OOS 4.1.6 but still no luck.
Next i moved to Lineage OS nighlty and tried StickMount(Root), Nexus Media Importer, USB Media explorer, USB Host Check(Root).
Still no luck. But USB Host Check App did give me information : android.hardware.usb.host.xml was OK but handheld_core_hardware.xml was NOT OK.
So i explored in this context and i found a missing entry inside handheld_core_hardware.xml. So i added that and did a reboot.
And set permissions to rw-r-r.
The USB Host Check app now says everything is fine but -
Still no luck.
Can i rule it as Hardware fault? :crying:
Anything else that i can try?
PS - Tried this connector with other devices and is working fine. Also, i tried connecting a mouse with my 3T, it is not working.
I have same problem. Please try to fix it asap. Thanks
Took it to service center where after 2 hrs of investigation, they ruled it as a strange hardware issue ans have asked for 3-4 days for getting and replacing the faulty part. It is 2nd day today, will comment again once i get my phone back.
Update :
So I got my phone back from the service centre. They have changed the usb component and now everything's working fine.

Hey,
I just rooted my Milestone and installed the latest CM7 ice & Fire, got the google apps and all that stuff done and the final problem I cannot solve is this:
It does not connect to the Motorola Phone Portal thingy, it says that it cant install the MTP USB Device which means I cannot connect to the portal to import my backup of contacts (MotoContacts.bak).
How can I solve this? I need to either fix the access to portal or something that can read out all the stuff from .bak...
Thank you,
Martin
set up your gmail account...
enable sync...
we have contact(s)
Uh, no
None of my previously on-sim-card and then attached-to-gmail/facebook contacts are there
Well it can't be that hard to get it to work.
Maybe you can try and re install the motorola PC software
Hey,
thanks for taking your time with this!
I have tried reinstalling the usb drivers with the portal numerous times and no luck since everytime i connect the phone it starts doing its own installing drivers thing which fails. I can connect to the MediaSuite but that cant handle the contacts.
I searched this and found the following quotes but no solution:

Edit: and another bug I found is in the camera app, if I select AAC for audio when recording video it Force Closes, and 12kbps for audio is just to low, so its kind of a major bug that needs to be fixed if possible, hope you can fix it
Forma portale and sync you have to reinstall portal.apk;
AAC bug corrected thx to kabaldan

I rebooted it already its just i can't switch to different modes... sometimes i can but rarely and it keeps say MTP USB Device driver install unsuccessful(something like that) and after i take the usb out the icon stays there, and also after i take the usb out and pug it in it says usb device unknown/not working.... usb is also not charging
here simple application that will enabled UMS mode for External sdcard
root needed.
how to use:
safe way on version 2.5 is :
enable UMS Mode when cable usb is unplug
Back to Charge mode when cable usb is unplug
safe way on version 3.0 is :
do it on condition usb plugged
note:
if you plug into player or some device player , and you found that it cannot found the USB drive
in this case just do this
settings -> connectivity -> usb connection type
and do press or repress the "Charge Only"
in version 3.0 you will notice 1 triangle on task bar, its normal , it telling you mass storage is currently unmount
2 icon on task bar is telling you the mass storage successful unmount you can take it out
those of notice are normal if we do unmount the mass storage in android api level.
all the information about how to do it i found on XDA forum.
i do some research also code this app
version 2.1
fix sometime fail to mount back to external_sd folder
version 2.5
fix sometime got to bluescreen on windows
version 3.0
fix bluescreen on windows
using different approach to unmount the external SD card
version 3.2
bring back native method to mount and unmount, its speed up abit when using native method
by check the box to enable native mode
version 3.3
support Jelly Bean
thanks are goes to XDA Members

Thanks for app. It is amazing
Best regards,
It does not mount back SDcard to /mnt/sdcard/external_sd after disconnect, so have to reboot after use it.
MTP is working but external_sd is empty.

With the first version I have access to the card. After disconnecting I have to reboot the phone, so I can regain access to the card.

Version 2.1 gives reproducible blue screens with Win7 x64 SP1 at the first link when I confirm the superuser, or in further tries, when connect the USB cable.
Only uninstalling the apk helps to solve the problem.
A little off topic:
After UMS_mode.apk does not work for me, here is another way to access both memory cards in the P880 (and any other Android-Device) from Windows OS:
Install Total Commander (Shareware): http://www.ghisler.com
Install Total Commander Plugin "Android ADB" (Freeware): http://www.totalcmd.net/plugring/android_adb.html
Android device driver has to be installed too!
Through links, both SD-Cards appear with 3 differen pathes in the P880 operating system.
The external SD-Card has its mount point in (!) the internal SD-card:
Code:
Internal SD-Card:
\\\ADB\LG-P880\data\media\
\\\ADB\LG-P880\mnt\sdcard\
\\\ADB\LG-P880\sdcard\
2. external SD-Card:
\\\ADB\LG-P880\data\media\external_sd\
\\\ADB\LG-P880\mnt\sdcard\external_sd\
\\\ADB\LG-P880\sdcard\external_sd\

thanks bro , here version 2.5 will fix the bluescreen
Thanks a lot! useful for syncing with doubleTwist. can't stand the LG PC Suite its too slow.
Sent from my LG-P880 using xda premium
version 3.0 relase fix bluescreen again,
if you suffer on always media scanning you can turn it off on
setting -> application -> find "Media Storage" -> disable
Wow!
This is the greatest thing created for this phone so far.
MTP is painfully slow, doesn't work with cars/stereos/etc, requires installing drivers everywhere I go, crashes all the time, doesn't allow access with a file path, and somehow caused my sd card to wipe itself three times in two weeks, so this was a major issue for me that was making me regret buying the phone.
Initially after installing this app (v3.0), I had to repeatedly toggle UMS/MTP mode and plug/unplug my phone from the computer several times before it finally started working, but now it's perfect.
If you have a paypal or flattr link, and I'll send something your way. Or put it on the Play Store so I can buy it and update
Thanks!
thanks

I can not confirm unfortunately.
I wanted to give the app still a second chance and have installed 3.0.
Then I restarted the phone, without starting the APP before.
Now it hangs on startup LG boot logo.
Even without the second SD card the same problem.
Any idea without factory reset or flashing KDZ?
My phone is still stuck in boot, but I have an access via adb shell to system.
Unfortunately I have no permission to access "/data"
Could anyone tell me the aplication name of this UMS-Tool under "/data/data" ?
I only found "com.noshufou.android.su" in classes.dex, but don't know wether this is right:
Code:
[email protected]:/data $ run-as com.noshufou.android.su
run-as com.noshufou.android.su
run-as: Package 'com.noshufou.android.su' is unknown
[email protected]:/data $
Ok, I guess it's not quite working perfectly for me now that I've used it a bit more, but I still love it.
1) it's really tricky to get it working initially. I almost always have to toggle it multiple times and sometimes reconnect the usb cable.
2) like someone else mentioned, it never remounts the SD card so I have to restart the phone to get it working again after I'm done.
I have not had any problems on boot like BudCord.
I'm running stock firmware 10f.
Anyone have v3 hosted any where else? I can't download from media fire.. no captcha support..
Tried stock browser, dolphin, and chrome..
Any chance to get it working on mac os x (10.6.8) ?
For the moment it is the only default i found with this phone : the lack of "connections" with Apple's OS :/
PS : I searched on the web and I found a solution for Mac OS X users : Android File Transfer (on the official website).
Sorry I can not the url because I am new on this forum.
I've added a few apps to my S3 and altered a few things on my PC and now I can't connect via mtp or ptp. It goes through the usual "installing drivers" and then fails. I've tried pulling the battery and removing the sim and micro sd card then putting everything back. Tried it without the card (currently having to transfer files via a card reader so - at least the card's fine) but to no avail.
I've had a go at uninstalling the drivers through the device manager, rebooting and scanning for hardware changes. I've tried downloading the drivers without kies but it didnt work out (I cant remember the site or the url, but ended up with the following file SAMSUNG_USB_Driver_for_Mobile_Phones) It didn't auto install but even when I tried to point Windows to the folder on my C drive, nothing.
I've spent a couple of hours trawling the net including on here and tried all sorts.
I'm rooted, using the stock 4.1.2 ROM with Windows 7.
I can't use Kies as when it was installed the first time it wrecked all my Synctoy sync's so I really could do with another option please guys.
Dial *#7284# on your phone to access PhoneUtil and select 'Qualcomm USB Settings' at the bottom.
Now select 'MTP + ADB' and press 'OK' to return to the previous screen. Now press your 'Back' key to exit PhoneUtil. Your phone is now back to default USB operation.

Thanks for the quick reply.I did that and it was set to mtp + adb...
When I then connected it it tried installing the driver and I got..
Driver device software was not installed.
Please consult with your device manufacturer for assistance getting this device installed
MTP USB Device X Failed
I tried updating the MTP drivers again from device manager but this time got
Windows encountered a problem installing the driver software for your device
Windows found driver software for your device but encountered an error while attempting to install it.
SAMSUNG Mobile MPT Device
This device cannot start (code 10)
From what I'm reading it's a computer error not the phone. Can anyone suggest a new set of drivers to download (that doesnt involve Kies) as I've had issues with picking up harmful software from random sites when I've been struggling to find drivers.
I tried using the suggestion at the bottom of here r.e.Portable Devices and deleting the Upperfilters string Link but also to no avail.
Oh, and yes I've tried different ports and cables.
Well that's me done for the evening! I've tried everything mentioned in this thread including updating java and windows media player and all the afformentioned stuff but still no dice.
Could it be the actual drivers or a random windows 7 setting that I haven't yet tweaked since my clean install of windows??

Here are the correct drivers, install then reboot your pc.

The newer drivers don't really wwork with the 9305 so find some older drivers. That works for me
Sent from my GT-I9305 using xda app-developers app
Thanks for the tip.any suggestions as to where I can download these older drivers? I'll try the previously mentioned ones first, but I'm starting to think it might be the drivers themselves

The ones I posted work fine on my 9305 so you shouldn't have any issues and as you can see from the site they are nearly a year old.
Try them what have you got to loose, if they don't work you are no worse off

Cheers, yeah, I was going to try them but I wasn't at my pc at the time I wrote that. I've downloaded the exe package but now it seems there are still drivers to uninstall - I uninstalled the drivers through device manager and went into my C drive and removed the SAMSUNG folder with the USB drivers in it. I'll restart the pc and hope that helps with the removal....

Having the same problem. but I am on 4.3 rom using carbon rom a few days then transferred to pac man rom. My cellphone is not detected in my computer but it is being detected in the safely remove usb options. I tried to use a usb otg cable and a flash disk. No notification is seen on my phone but I can access the files on the flash disk (using usb otg cable) in the file manager. Tried the *#7284# but error occurs and says connection problem or invalid MMI code. I found that MTP udb device says failed

It made no difference whatsoever. I used a utility to check for an remove the samsung drivers (USBDeview) as well as uninstalling through device manager and removing with windows "products and features" but even then, when I tried installing the new drivers it mentioned previous drivers. I restarted after each stage of the process.
I've even tried connecting it in download mode and it shows in device manager.
Could there be some remnant of the software I used to root that phone that might be causing the issue??
I'm due to leave the country in 5 days and have loads of things to sort (also have a family member going into hospital for major surgery tomorrow) so I can't just devote all my time to this - but I need to at least know that it's not the phone (I dont have another win 7 computer to try it on).

Just got the same problem. But my problem is already solved. Just flash a new rom. In my instance, I flash ripper rom
It started to stop, I suppose, after helium backup app install (both on android and on pc).
Strangely, with link2sd app (I don't have it anymore), I could see the notification for MTP and also the device in explorer.
But only for 5-10 seconds. Then stop to work.
I recently updated (via full wipe) from RR lollipop rom to RR nougat rom with similiar faults (so the issue isn't there)
On windows 10 often says "unrecognized usb device", this seems fixed now.
If I connect the x compact before the sp, both are recognized - so I suspect is not a driver/hardware issue.
But when I try open sp from file explorer... well, I don't see anything lol
What can I try? :cyclops:

Repair your phone via Xperia companion, this will install the stock rom. After that check if everything is working fine, if so install RR or Lineage OS and check again.
Sent from my Xperia SP using Tapatalk
Thanks, I solved. And the rom wasn't corrupted at all (okay, maybe the old it was).
However I put a microsd in phone (when I did rom/gapps/recovery update), then I clicked twice on "new sd" notification and now it seems that the MTP is correctly recognized
Probably, this, gave to phone the missing parameters for connection
Today when I was backing up my system (from orange fox) it suddenly failed and after booting up I can't use OTG devices, it was working untill then but now it doesn't work. I tried to use adb and it works.
I'm using crdroid 7.13 and dominator kernel
I tried to use mouse pendrive etc etc none of them work now
Does anyone have any idea
I saw another thread where someone claimed he knew but he didn't answer as the OP got it fixed by sending it to service center.
What happened exactly was that the backup failed for some reason I pulled out the usb(it was a sdcard reader) and rebooted the system and from then the usb OTG doesn't work for anything except for charging and to connect to pc.
