i had this issue before and fixed by re-installing the USB drivers.
http://d-h.st/a7H
I just got my Nexus 7(2013) device.
I used to transfer files between my computer and my Nexus 4.
When I plugged in my N4, my computer recognizes my N4 and device manager showed there is a portable devices "Nexus 4"
However when I plugged in my new N7, my computer cannot detect it and device manager showed "Android Device" with "Android Composite ADB Interface" under it.
I cannot find any new drive in My Computer although the device is charging through USB.
I have tried to disable/enable USB Debugging, using different USB cables, switching USB option between MTP and PTP and reinstalling Nexus usb driver from google and all of them do not work.
May I ask for any solution?
Thanks:fingers-crossed::fingers-crossed:
Uninstall/remove the drivers
reboot
then reinstall using these drivers

Even if you did it before, try again, with the removal of drivers and the reboot.
Also you may want to try different ports, cables, computers

I've tried that before
I may now try a few times more
By the way, I realized that I can use Wugfresh toolkit and completed the full driver test to bootloader mode. However, I cant even detect the hard drive.
I finally enabled to use PTP to access the photos.
However I am still unable to use MTP to transfer other types of files..
Any help?:fingers-crossed::fingers-crossed:

Please perform the following even if you have done it before.
In this current state, turn on MTP. Then turn off USB debugging. See if MTP shows up. If so, use this fix to get MTP working with USB debugging.

I am sorry that I cannot understand it completely.
May I ask
1. Should I uninstall just the entry with Nexus 7 as description in Nirsoft USBDeview and then reboot?
2. You mentioned that "When you turn on USB debugging and windows asks for an MTP driver, just provide mtp_driver.zip". How can I use the zip file? After rebooting and enabling USB debugging, my toolbar on bottom-right has a icon showing I have a MTP and I can choose to "remove MTP safely" just like plugging in a USB flash drive. However, there is not a hard drive in My Computer. Maybe is it the difference between Windows XP and WIndows 7? Or did I misunderstand your instruction?
Thanks for helping! :good:
I finally did it with USB debugging and MTP on.
I occasionally update the Android ADB Interface driver and install Composite USB Device from the list and my computer detects my hard drive!!
Is it possible to get my MTP working without enabling USB Debugging or is it normal to detect mtp with USB Debugging on? :good:

One of the drivers you installed previously which was modified to get MTP working. was implemented too aggressively and is now blocking your ability to use MTP with USB debugging turned off.
For normal systems with no drivers loaded, they have the opposite problem, in that they can get MTP working when USB debugging is disabled, but lose MTP when USB debugging is enabled.
When USB debugging is disabled and MTP is enabled, the USB port advertises that it is compatible with standard MTP drivers, so windows automatically installs. However if you have a custom driver installed, it can block that automatic process.
With USB debugging turned on, the USB port no longer advertises MTP compatibility, so windows is normally confused and doesn't know what driver to use. That you were able to get it working with USB debugging enabled proves to me that you have a custom driver installed that was modified to get MTP working.
The way I wrote my changes to the MTP driver was to leave the standard MTP alone and only intercept the MTP when USB debugging is enabled. Thus my changes don't block normal MTP operation when USB debugging is disabled.

Yes, but you are going to need to figure out which driver you installed is causing the issue and remove it so it doesn't get in the way.
Alternatively, try a different PC that has never had drivers installed and use just the one I pointed you at earlier.
You don't use the zip file directly, you unzip the contents and will have a .inf file.
When windows asks for a driver (USB debugging turned on and MTP turned on) you point the install at the .inf provided. It will do the rest automatically.

I have been using the same computer to root Galaxy Nexus and Nexus 4 and I remembered I have been using some tool similar to the one you provided.
Maybe it makes my computer cannot recognize the MTP
Anyway, Thanks
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
Any way to set MTP or PTP as default option on Android 7 ??? every time that I connect usb cable I need to set again!
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"
