3.3. Loading the Driver When UC20 module is connected with the Linux Kernel System mentioned above, the system will firstly recognize UC20 module and read its device descriptor, then create five interface devices automatically, listed as below. After that, you can use these five interface devices. - Page 15 You can check the result in the terminal, using the following command #ls /dev/ttyUSB* If the five device node files are listed, it is certain that the UC20 module has been recognized by Linux/Android OS. And the corresponding relations to the interfaces of the devices are shown as below:...
