Troubleshoot driver error

When the Android driver is properly installed, Device Manager (Start->run:devmgmt.msc) on your computer should look like this when your phone is attached:

In other words "Android ADB Interface" must be listed without error. If you do not see the "Android ADB Interface" device, try to make sure USB debugging is checked on your Android phone under Settings->Applications->Development or Settings->Developer (on Android 4.2.2 or above the developer options may be hidden, go to Settings->About Phone and tap "Build Number" 4 times to reveal it. If you already have PdaNet+ installed on the phone side, enable USB mode awill bring up the USB debugging setting if necessary):

If the computer side still does not install the "ADB Interface" driver when you plug-in your phone (PdaNet installation stucked at "please connect your phone"), there are a couple of things you can try:

  • With your phone connected, there should be a USB notification on the phone side. Open it and you should see two or more USB options (such as Mass Storage, Media Device, Camera (PTP), Charge Only etc.) Try to select each (skip USB Tether or Internet Sharing, if that is an option) see if any one of them triggers the "ADB Interface" driver on the computer side. For example some Samsung phones such as Galaxy S4 will require you to select "Camera (PTP)" for USB debugging to work.
  • With your phone connected, power off the phone and power back on. See if the computer side installs the ADB driver.
  • If USB connection does work for you before but is no longer recognized on the same computer, try to power off your computer and power back on and see if it helps.

Sometimes if there is a driver error on the computer side and no "ADB Interface", your system may need the official USB driver. If that is the case, install one of the following drivers on your computer first:

After installing the OEM driver plugin your phone and make sure the ADB Interface driver is installed this time. After that you can reinstall PdaNet and select "No" when it prompts you to reinstall the USB Driver.
