Hello I want to open a character device and read it so that my TUX module may serve data from the device in TUX modules. But "open()" always fails. In the case of a file, open() fails (No such file or directory) but tux(TUX_ACTION_READ_OBJECT, req) can read file into memory. I want to know how to read data from the device. I want to know better way about file. Thank you.
