Q:

Installing drivers from USB storage

How do I copy a driver from a USB stick and what directory should I put it in?
I'm using Raspbian. The driver is found here and it's for my TP Link usb wifi dongle: http://pan.baidu.com/share/link?shareid=340048&uk=3912523090
I know the cp command but I don't even know how to find the USB device, so please try to be as clear as possible.

A:

Your USB stick should be auto-mounted in /media.
If it isn't, mount it using mkdir /tmp/usb-stick && sudo mount /dev/sda1 /tmp/usb-stick. You might have to replace sda1 with the actual device name of your USB stick -- run ls /dev/sd?? to find out which name it has been assigned.
As for where to put it, the site where you found the driver already tells you:

Place the .ko object in the following path:
/lib/modules/(your-kernel-version)/kernel/drivers/net/wireless
