Android USB not recognized

Question

The programming on my Android device in Intellij worked fine for a while, and then all of a sudden my Android device started to not be recognized - "USB Not Recognized". I tried reinstalling my drivers, rebooting the phone, rebooting the computer and creating a new project, but nothing works. My phone is still recognized in about half the cases, but I accidentally get a USB Not Recognized error.

Answer 1

I just solved my problem with a really weird fix. It turns out that with a lot of wear and tear, the tongue (which is a small prong that is in the middle where the USB cable goes over the phone) that the connector goes through can bend. I understood this because pressing the front of my connector on the tongue made the connection work and push the connector up to stop the connection. I read somewhere that if you take a knife or a toothpick and gently push the tongue, the tongue will bend slightly and return to the position where it can form the correct connection, and, oddly enough, I tried, and it worked. Weird Hope this helps someone. Just do not click too hard on the language and do it only if you are sure that you have no problem with the driver.

Answer 2

Same. I get this error very often. Here is how I usually fix it:

Use a different cable.

Disable and re-enable Android debugging.

Reboot the phone.

Use a different USB port.

Use a different USB port with a different cable.

I do not know why. Anyone about who can answer this? :)

Answer 3

Settings → Storage. Click "Point Settings" USB connection to the computer.

Check the box next to "Media device (MTP)." If this check box is already checked, try checking / unchecking the box.

It worked for me

Answer 4

This works on ubuntu: sudo adb start-server

Answer 5

I just tried with USB and now it works great. Use your USB pin to push it by connecting it to your mobile phone. connect the cable to the mobile phone, then slightly move it in the UP direction. But be careful when doing this, as this can completely bend.
