PC no longer recognizing Android Device


While I never had problems before with my Android phone, suddenly one day when I was connecting my phone to the PC via USB it stopped working. Both my PC and my phone didn't detect each other. Strangely enough, it can still charge with the USB cable connected.

I tried the following with no results:

  • I supposed the cable was wrong so I bought a brand new one, but still both the PC and the Android phone refused to detect each other.

  • Checked in every port of my PC (I tested the functionality of the ports with a normal USB stick, and they work perfectly).

  • Enabled USB debugging option in the phone.

  • Tried to update USB drivers through Device Manager. The problem here is that it doesn't even show any Android device or at least an unknown device connected to the USB port, so I can't even force the search for new drivers.

  • I also tested both cables with two other Android phones I have (suspecting it was the fault of the phone), but still no results.

I'm using Windows 7 64-bit, and my phone has Android 5.0. I tested with a Samsung, and LG, and a Huawei but neither worked.

Do you have any idea or advice on how to solve this?


At the end, the problem suddenly faded away before even trying one of the previous solutions. This discards a problem with the USB connection, the phone, or the USB drivers from the PC.

My best guess is that a hidden update or a background program (of which I'm unaware of) was causing the problem, so if anyone has a similar issue, by best advice is to follow the advices of updating the drivers, restoring to a previous state, or just switch ports until finding one that works.
