Android device is not connected to USB for debuggi

Question

I am trying to debug my application using a real device instead on the emulator. When I try to connect, it gives me the message:

USB device not found

I tried to unplug and plug it again, but it did not work. And I have also enabled USB debugging and unknown sources options in my device.

Any help is appreciated!

Thanks!

Answer 1

For example:

My file path:

C:\...\sdk\extras\google\usb_driver\android_winusb.inf

My data to paste:

;Tablet PC

%SingleAdbInterface%        = USB_Install, USB\VID_18D1&PID_0003&MI_01

%CompositeADBInterface%     = USB_Install, USB\VID_18D1&PID_0003&REV_0230&MI_01

The solution for me was following the instructions at https://developer.android.com/studio/run/oem-usb.html#InstallingDriver. Specifically, the key part from that link that helped me to find the solution was this: "Install a USB Driver. First, find the appropriate driver for your device from the OEM drivers table below." This means that you cannot find a single link that applies to everyone as the solution. It will depend on your device! "So I visited the page to get OEM Drivers at https://developer.android.com/studio/run/oem-usb.html#Drivers. In my case, the device I was using was an LG K8 LTE. I had to go to http://www.lg.com/us/support/software-firmware-drivers#, Browse by product and I found the driver I needed under the Model Number "LGAS375 KG K8 ACG - AS375", Cell Phone Product. From http://www.lg.com/us/support-mobile/lg-LGAS375 I used the "Install the USB DRIVER" for Windows (http://tool.lime.gdms.lge.com/dn/downloader.dev?fileKey=UW00120120425).

Depending on the device model you are using, you will need to find the specific drivers that work for your phone, and that should work.

Many USB cables, specially Type-C, are for charging only.

From my personal experience, if you have a Type-C cable and you're having a hard time connecting your phone to your computer, you should try a different, high quality cable, specially the ones that says "Charging and Data" on the cover.

This solution works for every unrecognized android device... mostly general brands don´t come with usb debugging drivers...

• go to settings
• control panel
• hardware and sound
• device manager
• And look for any devices showing an error. Many androids will show as an unknown USB device or just Android

First thing you need will be your device IDs. You can get them opening up the device manager and finding the "Unknown Device" with a yellow exclamation point. Right click on it and select 'Properties', and then go to the 'Details' tab. Under the 'Property' drop down menu, select hardware IDs. There should be two strings:

USB\VID_2207&PID_0011&REV_0222&MI_01
USB\VID_2207&PID_0011&MI_01

Copy those strings somewhere and then navigate to where you downloaded the Google USB driver. Then you need to open up the file 'android_winusb.inf' in a text editor. I would recommend using Notepad++.

First, create a sub-section for your device. I called mine ';RCA 6378W2' but it doesn't really matter what you call it. Then, under the sub-section you created paste the Device ID strings you copied from the Device Manager, preceded by '%SingleAdbInterface%'. If you need help, look at this screenshot.

NOTE:

If you are using Windows 8 or 8.1, you will need to disable device driver signature checks before you'll be able to install the modified driver. Here's a quick video on how to disable device driver checks http://www.youtube.com/watch?v=NM1MN8QZhnk. Ignore the part at the beginning about 64 bit, your computer architecture doesn't matter.

Please look at this article, for more information and MacOS instructions.

Galaxy S7, I had to go to Settings, Developer Options and allow USB Debugging. This asked to approve computer it was attached to and it showed up instantly.

Answer 6

For me, this simple trick worked:

I actually enabled and disabled the listed USB Adapter for android in the device manager (Control Panel -> Hardware & Sound -> Device Manager). And holy moly it's working! :D
