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:
Sometimes if USB debugging is checked but there is still no "Android ADB Inteface" listed when phone is attached or if there is a driver error, your system may need the official USB driver for some reason. If that is the case, install one of the following drivers on your computer first:
- Driver for LG Android Phones
- Driver for Samsung Phones (updated for Samsung Charge/Epic)
- Driver for Motorola Android Phones
You must install the above Samsung Driver if you have the Droid Charge phone or Epic phone.
If you phone is a Motorola Droid X, an extra step is needed for this phone to expose the "Android USB Interface". After maksing sure USB Debugging is enabled, with your phone plugged in, go to the notifications list on the phone and select "USB connection", then "USB Mass Storage". See if the computer installs the USB driver after that and recognized by PdaNet. If not try to turn off the phone screen (press the power button) also and see if that helps.
If your computer runs XP, make sure it has at least service pack 2 installed.
