Need help getting drivers.

So I bought the first wifi adapter in this list: https://www.pandawireless.com/Drivers%20|%20Panda%20Wireless.html. Anyway I thought it would work with linux libre because I think the source is available, I think this because you have to compile the driver. I could be wrong. When I insert the device into my laptop it shows up but says "device not ready, firmware needed". I went through the instructions to get the driver but I keep getting errors when trying to compile it. I'm not sure if someone knows but does this device have any chance of working, or anyway to install firmware.
