For Linux, you don't need to install a separate driver, right? It's supposed to be included in the kernel.

Is Antminer L3+ still worth to buy? Can you recoup the cost of the device and make profit?

I got mine to work on Windows 10, but I can't get it to work on Raspberry pi 3.
I flashed 2017-11-29-raspbian-stretch.
sudo apt-get update
sudo apt-get dist-upgrade
sudo apt-get install -y libcurl4-gnutls-dev libjansson-dev
I downloaded bfgminer_5.4.2-futurebit2_linux_armv6.tar.gz.
I ran start_moonlander2.sh.
However, it says no devices found.
I'd appreciate any help!
Thanks!
