I want one simple application that will have ability to connect a usb device. There should be one button like Record. Everything that is coming from USB device will save in android device. As we click on stop button the application will stop writing in android file. Basically that USB device will be connected to some Kvaser hardware and will getting some data from hardware.
For example, see this mobile app. I don't need exactly like that but it can reflect what i need.
