Solution 1: Check Your Phone Set
First, you have to make sure that the physical connection is working. When your Android phone is plugged in, look for a USB icon on the row of icons at the top of the phone's screen. If you cannot find your phone, you should:
- Go to Control Panel > Administrative Tools > Services.
- Go down to Plug and Play and see if the status of it is "Started". If it isn't, right click it then select Properties.
- Set the "Startup Type" to Automatic then hit the Start button in order to start that service.
- Hit Apply > OK and then you can exit.
Solution 2: Change Another USB Cable If Your USB Hub is Damaged
Your micro USB hub in the phone can be damaged due to pin mis-contact or being constantly connected and disconnected due to a driver failure on your computer. To check if computer doesn't recognize Android phone because the USB hub is damaged, you can try another USB port, or you could try another computer.
To fix this problem, you can order one from eBay (a new USB hub costs only $7) and replace the old one with the newly bought.
Solution 3: Enable USB Debugging Mode
When nothing works, debug mode DOES work most of the time. This is the mode intended for developers. It allows you to directly access your phone, transfer and install apps without notification. To activate debug mode, follow steps below:
For Android 2.3 or earlier: Enter "Settings" < Click "Applications" < Click "Development" < Check "USB debugging".
For Android 3.0 to 4.1: Enter "Settings" < Click "Developer options" < Check "USB debugging".
For Android 4.2 or newer: Enter "Settings" < Click "About Phone" < Tap "Build number" for several times until getting a note "You are under developer mode" < Back to "Settings" < Click "Developer options" < Check "USB debugging".
With all these are done, you can then try to plug your USB devices in again.
Solution 4: Set Android Phone Connected as Media Device
There are two connection types for each Android phone or tablet: one is Media Device(MTP) and the other is Camera(PTP). If computer not recognizing phone, make sure MTP is checked
Go to Settings -> Storage -> More -> USB computer connection -> Media device.
Solution 5: Update Android USB Driver
Android USB driver is a set of microprograms to let the communication between computer and Android phone work smoothly. If you enabled USB debugging option but the Android phone is not detected on the PC. In this case, update the drivers on your computer to fix the problem.
- Click "Start" -> "Device Manager".
- Look for '"Universal Serial Bus Controllers" and click on it.
- Out of a number of options, choose "USB Root Hub", right click and choose Update driver. Do the same from Generic USB Hub and USB Root Hub (USB 3.0/3.1).
- Restart your PC and try connecting your Android phone and check if USB debugging is working now.
Solution 6: Update Android SDK If Your Phone is Not Listed in ADB List
If your Android device wasn't on the adb List, you can do the following changes to make it appear:
- Make sure USB debugging is enabled from device, and do the following on your PC:
- Update Android SDK (Google USB drivers updated)
- From PC Control Panel, System -> Device manager -> Nexus 4 (the name of your Android device, here we take Nexus 4 for example) -> Install driver.
- Set Android SDK as path to search, include subfolders checked. After that, adb devices list will include your Android device.
Solution 7: Update your computer
Sometimes outdated system (most often Windows) will not recognize any Android device (or any USB device). And it's always a good idea to update your system. Remember not to install too many updates at the same time (not more than two or three), though.
