How can I get the id (or some unique properties) of the USB devices connected to my Android device?

回答1:

For anyone new to UsbDevice, it may be worth noting the use of UsbManager

UsbManager usbManager = (UsbManager) getSystemService(Context.USB_SERVICE);
HashMap<String, UsbDevice> usbDevices = usbManager.getDeviceList();

You can get the unique ID of an android connected USB device using UsbDevice.getDeviceId() method.

Please check the below links for more details. http://developer.android.com/reference/android/hardware/usb/UsbDevice.html#getDeviceId()

More than Id, Please check other methods of class 'UsbDevice'. http://developer.android.com/reference/android/hardware/usb/UsbDevice.html
