Android not connecting to pc (ADB)

I have been trying to connect my Huawei phone to pc but there is some problem. I turned on USB debugging and also turned on Allow ADB debugging in charge-only mode but still, this problem persists. I plugged the USB cable into a different USB port but still, I can't connect my phone to pc.

Try to Enable the following:
Always prompt when connecting to USB.
Allow ADB debugging in charge only mode.
Verify apps over USB.
Increase readability under sunlight.

I will advise you to try with the USB mode (Transferring media files via USB). USB debugging is a feature which allow developer to debug/run application on physical android device. So, this includes file transfer between pc and your device. If the problem still persists, please check the USB cable.
This article is an official documentation from google. I hope it will give you more insights about USB debugging.

How to deactivate a specific USB port on Android device

I'd like to power on and off a USB device in Android. I know the method on Linux and it is pretty straightforward (see https://loginroot.com/power-off-and-on-usb-device-in-linux-ubuntu/). Unfortunately the command lsusb -t does not work on Android terminal.
Do you know how to deactivate a specific USB port on Android? Alternatively, getting the USB device tree should be enough, but I don't know how to achieve that either.

Communication between android app and pc application through USB

I have my android tablet connected to windows pc machine through USB cable. I don't have internet connection.
I need a solution to establish a connection and transfer files from pc to android app. I think we can use Android open accessories in accessory mode. Is there a better solution to solve this problem or is android open accessories the right solution. What are the shortcomings of this solution ?

you should install the drivers for your tablet and to transfer the files using usb. Your android tablet tablet might not be recognized without drivers. Also you should store the files inside download folder to be easily visible by the pc.

Broken Windows-Android USB-Connection between Device and PC

I've done a lot of research about rooting a device but I can not even come up to this point because my phone is not recognized by windows 8.1 at all.
My intention is to establish a usb-connection between an android-device(Samsung GT-I9506) and a pc in order to use it for phonegap. Some other devices properly work collaboratively with phonegap but this one seems to refuse all attempts.
Important points:
1. The device is charged up when connected to a pc.
2. Use-Debugging is enabled
3. All drivers are installed, furthermore it's a Samsung PC and Phone
A related topic is this one: USB connection issues
But unlike the problem in the topic above my phone does not appear in the adb-list when entering:
adb devices
I plugged my phone into another pc(Windows 8.1) as well where it was not recognized either.
Thanks in advance.

If your system installed Android ADB Interface Driver then only you can see your Device in IDE.
You can check that
Go to Control Panel
Go to Device Manager
And find Android Phone like

It turned out that the usb cable was the reason for broken communication between pc and phone.
Strange enough that this faulty cable was able to load the phone but unable to establish a communication channel to other devices.
And the moral of this story is a usb cable of a smarthphone might be faulty even if other electrial supplies are still intact.

USB connection between Odroid and PC

How can I send bytes between Odroid with android and my pc? I want to use usb but I am looking for someone who do that and can help me. I don't know how can I start with that.

Enable Developer option from android setting and restart your adb. Odroid is able to connect with usb like normal device.
