I want to develop an application which takes user's fingerprint, photo and other necessary information. I have TSP450 and S8 machine, I started to write the application according to your shared demos and user guides. However, mUsbManager.getDeviceList() returns 0, I think it should not return 0, cause there has fingerprint module in it. I understood that we connect with fingerprint module via USB interface, so it is necessary to get the device list and device. If I am wrong, please enlighten me. By the way, some of the shared .apk did not work. Just Bio Mini Sample app(104641_fingerprintbiominisample-v2.1.0.343.apk) worked in the tablet. Also, can you share more detailed userguide or bio mini sample source code?
Thank you.
