this is a linux based gaming console
it works out of the box using the usb cable for both NAND memory and SD memory
To gain root access to the console the usbserial app need to be launched on the console and the usbserial module have to be loaded on linux.

Ubuntu users could need to add:
usbserial.vendor=0xXXXX usbserial.product=0xYYYY
to the grub's kernel line, where XXXX and YYYY can be obtained from lsusb
the USB Network module works fine without any manual configuration, just to launch it from the console.
