How to get android device model number connected to a PC via USB? How do I get the android phone model number from a Windows PC connected via USB, provided all the USB device drivers are installed properly? Is there anyway to get it via Android SDK?
I don't know how to get it by the adb command.

But you can get it programmably with the SDK. There is a class Build which have many information of the current running phone, such as you wanted model number can be got by the Build.MODEL.
