<p>I think these might be rebranded ZeusMiner ASICs - LKETC doesn't appear to sell any scrypt miners below the 1MH/s range. Also, some of the reviews on that item say that they've had luck on linux with a fork of cgminer with ZeusMiner support.</p>

<p>There are two drivers you need. You need a driver for the USB-to-UART bridge, and a driver for the ASIC. The former is distributed with Raspbian, assuming the bridge is a Silicon Labs CP210x. (I think it is, based on the screenshots on that page.) The latter is usually distributed with your mining program of choice.</p>

<h3>Possible fix</h3>

<p>All instructions are intended for Debian/Ubuntu/Raspbian.</p>

<pre><code>$ sudo apt-get install build-essential libtool autotools-dev autoconf git
$ git clone https://github.com/dmaxl/cgminer/ &amp;&amp; cd cgminer
$ ./autogen.sh
$ ./configure --enable-scrypt --enable-zeus
$ make
$ ./cgminer
</code></pre>

<h3>Troubleshooting (if that doesn't work)</h3>

<p>When you plug it in, it should create the device /dev/ttyUSB1, and a device under /media or /mnt. You're interested in the first one.</p>

<p>You can get a list of devices that are plugged in with <code>lsusb</code>.</p>

Hi, I have confirmed the drivers are Silicon Lab CP210x.  I have downloaded the Mac versions from here : https://www.silabs.com/products/mcu/Pages/USBtoUARTBridgeVCPDrivers.aspx.  I am going to try what you've typed out and see how it goes.  Is there a preferred Pi Image that I should start with to accomplish this?  I only have access to a NOOBS starter image, but I think I can figure out how to download and clone a new one (if you can point to one that is most appropriate).  Many thanks @NickODell.

HA, look what I found.  http://www.aliexpress.com/item/USB-Litecoin-miner-LTC-144KH-S-280KH-S-usb-miner-for-Asic-Miner-Collectibles-Christmas-gifts/32240507679.html.   This may not be rocket science, but perhaps it is helpful to you?  The images show a step-by-step process for Windows.  There is an app called LKController??  Do I need something like this for Pi / Mac to work?  How very odd.

<p>you can download source code here : <a href="http://github.com/wareck/cgminer-lketc" rel="nofollow">http://github.com/wareck/cgminer-lketc</a></p>

AH.  I think they are a bit of both.  They come with a 8GB built-in storage capability (which shows up on my Mac Finder as a couple of folders with some apps and drivers.  The drivers are Silicon Lab - so I went to the web site here : https://www.silabs.com/products/mcu/Pages/USBtoUARTBridgeVCPDrivers.aspx  and found the MAC version of the drivers (installed them) and still no luck.  The device is a Miner by functions.  The memory is a small add-on.  Does this help?

I tried both the tty.SLAB\_USB\* and cu.SLAB\_USB\* devices, only the cu.SLAB\_USB\* seem to work. Make sure the switch is in the proper position on each USB stick (switches to the right)

Startup cgminer using the command:

You can adjust the clock frequency, provided you have a fan.

Took me AWHILE to figure out how to make this cheap piece work with straight cgminer in linux...

First grab the cgminer version from <https://github.com/dmaxl/cgminer/>

After you configure it with --enable-scrypt and --enable-zeus...

sudo ./cgminer --scrypt --zeus-chips 1 --zeus-clock 200 -S /dev/ttyUSB0

Use lsusb to figure out what the USB # is and you can crank the clock from 200 - 300... maybe more... It'll get hot and need a fan, if you crank it up too much.
