How to Fix ADB USB Issues

When using a SmartHub or SmarTab there are a few things you can check to verify that ADB USB is working. First, you must install the ADB drivers and follow the instructions in this article:

Once the drivers are installed, the next thing to check is whether or not the device shows up in the device manager. The device manager will show either "Android Phone/Device" at the top or "USB Composite Device" under USB Serial Bus Controllers. 

If the device shows up as "Android Phone" then type "adb devices" in the command line. If the device doesn't show up when typing "adb devices" then follow the steps below (you must at least be connected over the SmartHub's hotspot):

In most cases, the above process should work. However, if your device shows up in the device manager as anything besides an "Android Phone" you can follow the process below:
  1. Right click the device in the device manager.
  2. Click "Update Driver" from the drop-down menu.
  3. Click "Browse my computer for driver software"
  4. Click "Let me pick from a list of available drivers on my computer"
  5. If Android models don't automatically show up then uncheck "Show compatible hardware" and pick "Android" or "ClockworkMod" or "Google" under "Manufacturer"
  6. Then click the appropriate model for your device (generic models for android work just fine) and click "Have Disk"
  7. Then click "Browse" and navigate to the folder where the ADB drivers were installed. This folder is often located here: C:\Windows\System32\DriverStore\FileRepository (the driver will likely be named "Android_winusb...")
  8. Click on the .INF file which will be of type "Setup Information" and click "Open" and then "Ok" under "install from disk"
  9. Click "Next"
  10. A popup may show after clicking next that states the driver is not digitally signed. Just click to install the driver anyway.
Below are screenshots of the entire process:

If none of these methods work, you may need to check that your wire isn't damaged. A continuity diagram is shown below:
