[android] Android ADB doesn't see device

I'm trying to run my applications on OMEGA T107 tablet. But adb doesn't see my device. I tried almost everything.

This question is related to android adb tablet

The answer is


On windows, you will need to install drivers for the device for adb to recognize it. To see if the drivers are installed, check the device manager. If there is any "unrecognized device" in the device manager, the drivers are not installed. You can usually get the adb drivers from the manufacturers.


It worked for me in my Astro Tab A737 Download and install PdaNet+ from http://pdanet.co/a/ in your computer.

follow all steps in the wizard while installing .Once the drivers are installed Android studio should recognize the tablet.

Also, make sure the device is in PTP mode.


Not all USB cables can transfer data. Try using a different USB cable if your device is charging, but doesn't establish a connection to your machine.

It seems trivial. But it's worth a try if each and every other solution that normally works, doesn't.


I had same issue, none of the solutions worked for me.

Open Settings Menu -> Developer Options -> USB Debugging should be on


For Windows 8 64 bit with a Nexus 10 device, this worked for me:

On Windows it is most probably that the device drivers are not installed properly.

First, install Google USB Driver from Android SDK Manager.

Then, go to Start, right-click on My Computer, select Properties and go to Device Manager on the left. Locate you device under Other Devices (Unknown devices, USB Devices). Right-click on it and select Properties. Navigate to Driver tab. Select Update Driver and then Browse my computer for driver software. Choose %ANDROID_SDK_HOME%\extras\google\usb_driver directory. Windows should find and install drivers there. Then run adb kill-server. Next time you do adb devices the device should be in the list.


Debugging needs to be enabled on the target device in order for adb to see it.


What operating system are you on? If you running Windows you will want to make sure you have the drivers. You should also make sure that your Android SDK Manager is not only installed, but it also contains some additional things for different devices. Not sure if yours is in there or not.

Make sure that your phone has debugging enabled. I found myself having to run

adb kill-server

adb devices

often.


Uninstalling all old "Android ADB Interface" drivers that were installed previously and then installing the new one worked for me.


The normal way to fix this is indeed to restart the adb server :

adb kill-server
adb start-server

then

adb devices -l 

should list connected devices

But it possible that it doesnt fix the problem. It appends to me.

I had to disable/enable the debug mode on the device, and then restart adb server.


Some of these answers are pretty old, so maybe it's changed in recent times, but I had similar issues and I solved it by:

  1. Loading the USB drivers for the device - Samsung S6
  2. Enable Developer tools on the phone.
  3. On the device, go to Settings - Applications - Development - Check USB Debugging
  4. Reboot O/S (Windows 7 - 64bit)
  5. Open Visual Studio

I think it was step 3 that had me stumped for a while. I'd enabled developer tools, but I didn't specifically enable the "USB Debugging" but.


Intel has a peach of an article on this. It's all the same driver. It's just a Device ID mismatch in the Inf file which can be edited, or Windows forced to Install the driver we point it to. Intel's article is very thorough and takes care of every hurdle you come across. The link - https://software.intel.com/en-us/xdk/docs/installing-android-debug-bridge-adb-usb-driver-on-windows
