At OxygenOS 12 adb works only in file transfer mode. If I won't enable it, adb devices lists nothing.
Is it bug? Or maybe there's some kind of option switch for it? Didn't find anything in developer settings so far...
Edit: I've just discovered that if I'm connected to adb (debugging enagled, authorized, usb in file transfer mode) and then change mode to charging only, then usb debugging is disabling completely in developer settings.
And I can't use adb in fastboot/recovery mode.
Yes it is true u cant usb in charger-only mode
Because there is written already "Charger-Only"

I used Helium to change to USB PTP mode and now mine tablet isnt recognized when connected to PC. Want to change it back to MTP mode, but I cant find anywhere in the settings to choose betweens USB modes and I just dont know how Helium broiught me there.
So where is this USB mode settings hiding in the settings?
edit:
Managed to change it back to MTP mode, be secret code *#0808# and there are few choice to choose from. I chosed just MTP, but there is also MTP + ADB and does it matter which to choose? Since the tablet is still not recognized when connected to PC as it used to do before?
Also, USB Mode is suppose in storage settings, but there is no ways to access it by just go into storage settings and only through Helium app. How do you enable this hidden settings in Storage?
Normal there should be "3 dots menu" to get there, but there isnt in mine tablet and do Samsung hve removed it or its a bug?
edit2:
Fixed it, by uninstall Helium and few other apps. After reboot and tablet is recognized when connect to pc and got USB mode choice by pulling notification down.

How did u dial *#0808# on a tablet?... I am having a issue connecting my tab to a computer. I have no idea where mtp mode is on this thing
Is there a trick to make MTP work under Windows 10? I used it once (via the swipe down, hitting the USB Mode and changing to MTP) before enabeling develper mode.
Now in Developer mode I changed it under Network --> USB Configuration --> MTP but my tablet does not show up on my PC. Do I need to change anything else? Already tried switching between the USB configurations, rebooting the device and so on, but nothing seems to work...
May be wrong but:-
W10 out of the box doesn't support MTP. You may need to install the Android Debug Bridge USB driver on your Windows machine and then connect that driver to your Android device. With the tablet disconnected open W10 Device manager, now connect the tablet to the USB port. Device Manager screen should immediately refresh and show 2 lines at the top of the screen:
Android Device
Android Composite ADB Interface.
Assuming your cable is ok then the absence of these two lines indicates you need the driver installed. The driver is installed as part of Google's Android Studio in the Platform Tools sub directory. If you just want the drivers then they are available to download (no links ) There are automated methods , see http://forum.xda-developers.com/showthread.php?p=48915118#post48915118 or Nexus Root Toolkit does it. ( You should have usb debugging enabled in the tablets Developer menu)
Once the drivers are installed then when you enable MTP via the Notification or your menu "path" then Device manager will show the tablet under the "Portable Devices" line.
I originally got my laptop to work with the Pixel C using Window 8.1. I had trouble at first finding a driver that would work. I tried various drivers, but I eventually got it to work with PDANet. I believe that the trick for me was to first use PTP to get the correct drivers installed. You should be able to switch from PTP to MTP once PTP is working correctly.
I have subsequently upgraded from Windows 8.1 to Windows 10. I had a similar issue again with the drivers. I first used PTP to get the proper driver installed and then switched to MTP.
I always use the pull down menu on the Pixel C to change from charging to PTP once working and then to MTP.
With PTP, you should be able to see the Pixel C drive on the computer but only able to access the photos. Once you switch to MTP, you should see all the folders.
For fastboot, you need to use PTP and not MTP.
Found this post via Google, it's an issue for me with the Pixel phone, too. Photo mode works normally, MTP doesn't.
For others who also find this post, I read that supposedly the Pixel phones install ADB drivers automagically, but this isn't happening for me, and @SmokinCharger's fixes haven't worked either.
If you have developer option enabled, there is a settings under NETWORKING that lets us set the default mode when connected via USB. I've set it to MTP but yet, each time I connect the phone to my computer, it is still just "charging" mode.
Anyone have any luck with this?
Also, anyway to disable the D drive prompt? <-- this is one of the Windows that occasionally pop up and contains the setup files (for Windows). I wish we can just delete this thing and free up some extra space.
Is there a way to stop the HiSuite image from mounting when connecting via USB? Mate SE, Android 8.0 (ota), rooted, macOS.
If you change the developer settings to usb debugging, usb allow adb debugging in charge only, and usb connection to charge only, that will avoid the hi Suite stuff.
If you change the settings and then connect, keep the settings app open, for some reason you have to go back and reset them again after connecting. At least that's what I have to do, they don't seem to stick.

Thanks!
Just to follow up, I discovered a more permanent solution, if you're rooted:
Rename (or delete) the file autorun.iso located at /data/hw_init/version/region_comm/oversea/cdrom
Can't mount it if it's not there
Hello,
Im transfering some files into my pc but it asks me to enable camera ptp mode. I have already enabled developer options and USB debugging. However, I can't seem to find anything that changes into ptp mode. Where can I find it?
