Usb debugging blocked by knox? - Samsung Galaxy J7 (2017) Questions & Answers

I've enabled developer options and usb debugging. I can successfully mtp files but no matter how many times I clear and reauth my debugging permissions adb shows the device as unauthorized and easytether wont work either. I've never seen the debugging mode icon come up, only ever mtp. Did these clowns really go to such lenghts to not only lock the bootloader but disable things like debugging period?

[q] debugging mode

I am trying to use my rooted galaxy s5 sm-g900f in debugging mode, and when I enable the mode it works for 5 second and than reconnects to the pc not in debugging mode. the option stays ticked but if I go back and getting in developer options again it isn't ticked. it is not a problem with the computer because it happens even when it is not physically connected with a cable.
Thank you for helping

Nexus 6p 7.1.1 can't authorize USB debugging

When I enable USB debugging on my phone I don't get the option to authorize my PC.
Make sure your drivers are installed correctly. If you used a toolkit, uninstall them and then reboot. Install them using the Android SDK. If the drivers are installed correctly, click the "Revoke USB Debugging Authorizations" option from developer settings. Toggle USB debugging off and back on, then unplug the phone and plug it back in. Should pop up for you.

[Q] Debugging mode on, no usb connection options

so i'm trying to adb to my phone. rooted, unlocked, all that done. just trying to adb in. i have debugging on, phone will charge only. not notifications telling me anything. go to developer options, try to change connecting to mtp, or ptp, select it...and...charging only. i turn off debugging and then plug in usb and all options are there and work flawlessly. i am on ubuntu 16.04...all adb is up date, etc...searched and searched...and nothing for my exact problem. thank for any help. not a noob...just a lost tinkerer.
also with debugging on, lsusb doesn't show nexus. but does with debugging off.
So no one has a clue? I've done lots of searching...Everything from updating SDK, Android.rules, deleting keys (there were none), .Android folder keys, everything possible. ADB works in TWRP. Fastboot works. But still same problem...

Any custom ROMS that have developer mode and USB debugging enabled by default?

Anyone know any custom ROMs that have developer mode and USB debugging enabled by default? I want to be able to have continuance access to the phone from my computer even after doing a full factory reset without touching the phone.

Likely not, at least wrt USB debugging, as that would introduce a significant vulnerability. Not sure a ROM developer/maintainer could 'force' debugging mode enablement on initial boot even if desired.
