Yup, I've had mine a couple weeks. Thinking about another one, but it only earns about $4/month. I use it with an old Linux laptop, but I've got a few Pis, no spare monitors right now so I use my $1 laptop (HP, circa 2008).
Load a Rasbian onto a SD card, a 32 gig one is probably plenty big enough. The main mining software is cgminer or bfgminer, one was based on the other so they're very similar. There are maybe dozens of forks (variants) of each. I use a cgminer by dmaxl from
https://github.com/dmaxl/cgminer/archive/master.zip Most recent cgminers don't do scrypt or gridseed, this does both. You'll need libcurl, libusb, probably something else, it's in the readme in cgminer. The forum at raspberrypi.org is good, but most people there aren't really into mining. Here is good but most seem to use Windows. Install Synaptic to make managing packages much easier. Don't sweat the Raspbian updates, once a month is plenty often enough.
Sign up at litecoinpool.org. I start my cgminer with the script:
#!/bin/sh
./cgminer --scrypt --no-submit-stale --user ab1jx.7 --pass 7 --api-listen \
--net-delay --url stratum+tcp://us.litecoinpool.org:3333
(replace the ab1jx stuff with your username)
But I also have a cgminer.conf with the magic line:
"gridseed-options": "freq=700"
to speed it up. You can go up to maybe 900 I've read, I'm having a little trouble with this happening, trying to narrow down what causes it.
