Use Arduino Yun as Dattalogger

Hello Guys

I want to realise a datalogger with Arduino Yun because this last has many interesting speficities (Micro SD , USB Host, Ethernet etc.). Now, I would like to know if I can etablish communication between the microprocessor of Arduino Yun and Usb Host and Micro SD directly without using the Microprocessor Atheros based on Linux ?

Thanks

yes you can. But then why would you need a yun? Most of those handy peripherals you mention are accessible through the Atheros side of the board.

In fact, I don't master the Linux Environment

You don't need to "master" it. At least is a cool way to learn useful stuff about it.
