Android Device not recognized in Visual Studio/Android Studio

Hello guys,
i spent the last 3 days with my problem:
I want to use my Samsung A40 for debugging in Visual Studio but it doesnt show up. I plug in, install Samsung ADB Drivers and it shows me a working "Samsung Android Interface" in the Device Manager. I can also access the data through windows explorer without any problems. But when i use command "abd devices" i get an empty list.
What i did:
- enable USB Debugging
- Change Protocols
- Install ADB drivers
- Different cables
- Different USB Ports
- Deleted adbkeys
- Created adb_usb.ini with Vendor IDs
and so on...
I got it to work on my private computer and on another computer at work without any problems. But here it just doesnt want to pop up.

Connecting OnePlus One to adb

I have latest Android Studio installed and Android Debug Bridge version 1.0.41.
In Android Studio SDK Tools I have installed Google USB Driver v12.
My ONePlus One has Carbonfibers ROM, has developer options turned on and Android Debugging turned on.
When I plug in OnePlous One I get no mobile notifications and nothing in Win 10 Pro.
Device Manager / Portable or Other devices does not have the phone beneathn it.
When I run adb devices in cmd there are no devices attached.
I cannot find a OnePlus One adb usb driver.
Any suggestions how to diagnose this problem and get my OnePlus One recognised by adb?

Unable to connect to usb
I installed Carbon-cr-5.1-moo-release-bacon-20180202-1444.
I am unable to get usb connection working and having tried many different things...
-I have latest Android Studio installed and Android Debug Bridge version 1.0.41.
-In Android Studio SDK Tools I have installed Google USB Driver v12.
-I have developer options turned on and Android Debugging turned on.
-When I plug in OnePlous One I get no mobile notifications and nothing in Win 10 Pro.
- when I go into developer options and hit 'select usb configuration' my selection of mtp or whatever is always ignored and charging selectiomn remains
-Device Manager / Portable or Other devices does not have the phone beneathn it.
-When I run adb devices in cmd there are no devices attached.
-I cannot find a OnePlus One adb usb driver. I thought I found one but I have no way to verify and after installing it made no difference
I want to update to the latest rom in case this may be the cause, but after I download it to the phone and click flash
I just get the oneplus icon forever and the recover app twrp does not come up. It used to be there but then after I installed
the first rom after a couple of uses it disappeared for some reason or at least will not boot to it.
When I installed that first custom rom I folowed instructions for rooting and on completion it says to open up the installed
su app but when you open it it says there is a more up to date version but when you try to install that it fails.
Now all the apps that will not run if your app is rooted say it is rooted and all the apps that will not run unless it is rooted
say it is not rooted.
I think I need connection via usb in order to reinstall the twrp recovery app in order to install an up to date rom, hoping this may help
me solve the usb issue, but I cannot get the usb connection working as described above,
any hehlop would be appreciated.

Question Phone can't recognize USB or ADB

Hello all,
My OnePlus 7 Pro, can't recognize USB through my Windows PC, I don't get the prompt to connect to my Win PC.
Also I enabled ADB with Developter Options. I go to fastboot and also after adb devices and fastboot devices command, he can't recognize my device.
My OnePlus 5T is working with ADB and normal USB Win PC, tried two cables and laptops.
I did an run Android 10, now 11, beta etc nothing works! The phone can charge etc.
Please help. Reset etc tried also.

it is known issue ADB don't work on USB 3.0 ports
just goto BIOS > Advanced > USB > XHCI and change the setting to Disabled.
This will make the ports run in USB 2 mode, and fastboot and ADB works as usual.

Can't confirm this. At least latest version of ADB works at me with USB 3.x ports.

Nvm I didn't read the thread well if the PC can detect the other phone on ADB perhaps you can try "revoking USB debugging authorization" so it would ask for permission again

How can I get my Pixel 2 (walleye) to connect to ADB?

Hello,
I recently got a Pixel 2 on stock Android 11 with the intent of flashing LineageOS + rooting. But I haven't had any luck getting ADB to recognize the phone so far. I am using Windows 10 and Ubuntu Linux 20.04 LTS.
As a prerequisite, I enabled developer options, USB debugging, and OEM unlock.
I'm pretty sure the USB port of the phone is okay because the phone still fast charges.
Here's what I've tried:
- using Minimal ADB (device does not appear when adb devices is run)
- using platform-tools ADB (same as above)
- using wireless ADB (ADB is able to pair but the phone still doesn't appear when adb devices is run)
- checking Device Manager (device does not appear)
- Installing Google USB drivers
- using OEM cables from Samsung and other Android OEMs
- using a micro USB cable with a micro-to-C adapter
- using a USB hub
Am I missing something? What should I be doing to get my phone to be recognized by my computer?
Thank you in advance.

Hi, sounds like you've tried all the usual trouble shooting bits with cables, ports etc. Only other things I can think of at a stretch are to try enabling file transfer when you connect to a pc and see if that makes any difference or booting into bootloader via the button combo from powered off and then running fastboot devices from your adb and fastboot to see if it is recognised in fastboot mode?

Updated to OO13, now can't connect to PC

Hey guys,
As the title suggests I've updated my 8T from OO11 to OO13 and now my phone isn't recognised in my computer at all
Nothing comes up in device manager when I plug the phone into the computer
I've tried
- 3 different usb ports
- 2 different usb a to c cables
- USB debugging is enabled
- Installed oneplus drivers
- Installed google usb drivers
- Switching default USB configuration to MTP
- Using MTP, PTP, No data transfer
Still nothing is showing up in device manager
The phone charges when connects to the computer, it doesn't prompt me to allow USB debugging on my phone, despite revoking old usb debugging authorizations
I need to use adb commands to enable volte using the Shizuku method but I can't do that as the phone isn't recognised at all
If anyone could help that'd be great, otherwise I'll have to rollback to OO11 and use the pdc method
Thanks in advanced!
