I currently have 5.1.1 installed on my honor 5x and am able to use adb automatically without accepting an RSA prompt (have installed twrp, rooted, etc.) but when I dload a MM stock rom and use usb debugging it is unauthorized and I get no RSA prompt I've even gone as far as to delete /data/misc/adb from my device and adbkey.pub from my desktop but there is still no pop up authorization in MM
Developer options -> Revoke authorisation (something like that), replug. If that doesn't help, change connection mode to file transfer and try again.

I actually don't have a "revoke authorization" button below usb debugging, odd I know but I've tried all those options to no avail

Tried toggling the debugging switch? I had issues like these on one of my previous devices, but usually these were fixed with a simple port change or debug off/on switch, if revoke->replug didn't work.
Have you checked drivers, or if dmesg says something about the device, if you're on Linux? Sometimes even running multiple adb instances (like one from terminal and one from Android Studio, for example) can cause this behviour.

Hello,
I have some rooted devices running under android 5.0 in with I have removed some stuff + the settings. BUT the user is able to add applications - including wifi managers- thru ADB commands.
My question is : can i disable the USB debugging thru a command of ADB?
I have a jp5s tablet running android 4.2.2. It is a prison issued tablet. USB debugging is not enabled, and you can't enable devlopers options. Bluetooth works but app installation is blocked for security purposes. And the ability to allow unknown sources is disabled. Recovery mode only has reboot now. There is no fastboot so adb on windows will not connect. My only idea is maybe a picture or video file that runs a script to allow USB debugging, or installs an apk(a file manager). Also I'll pay for one that will set my devices year back to 2011 or so. Please any help or advice. Maybe a windows program that will force connect adb somehow.
Yeah you can go to settings but its very limited, pressing build number only brings up a list of installed apps.
Nothing google at all its a prison tablet that's the issue I want to install apps

Hi , can you post video on YT in order to see what is actually happening your device.
Yes I do, I need to install a 3rd party app
I have recently installed an application that refuses to open when developer mode is activated or the usb is enabled to pc, I tried alot to extract files of this app and i don’t know which file i’m gonna find the code making this action, So what should i do to use this application in both developer mode and usb debugging?
Note: when i enter the app it shows an error that order me to disable developer mode and then the app is closed by it ownself.
Try

Hi
I have a google pixel with a broken screen. I have recovered all of my data before. Since it has a very good camera I just want to use it as a webcam. but to install the apps I want (like droidecam or etc) I need to use Vysor. to use Vysor I need usb debugging access and etc. is there a custom rom or android that has usb debugging activated and allows my pc to connect?
