Add USB Ethernet adapter
piCorePlayer includes the extension net-usb-KERNEL.tcz on the pCP image for those occasions when you have a RPi with a spare USB port but no Ethernet port and want to connect to a wired network. By default this extension is not loaded.
To facilitate a headless install of net-usb-KERNEL.tcz, piCorePlayer looks for a file named netusb on the boot partition.
