I just bought one of these on a well known auction site.
Getting it to work took a while. The stick is often unbranded, and sells under various titles like "Litecoin Miner mining ASIC 8G USB", "Dogecoi ltc Litecoin Miner mining ASIC USB All SCRYPT Coins Virtual Currency" (yes misspelled Doge), or something similar.
Mine had the following attributes in the description:
Brand : YuDianHuiXin
Model : Litecoin Miner 8G
MPN : Does not apply
Type : USB Block Erupter
Processing Speed (GH/s) : 144K/S-280K/S
Power Use (W) : 5
Compatible Currency : Dogecoin
Not much to go on, and the type was definitely misleading.
Thanks to @ngdias! The first post in this this thread had the last bits I needed to get it working. This is what I used:
bfgminer --scrypt -o stratum+tcp://ltc.ghash.io:3333 -u <worker> -p x -S zeusminer:all --set zeusminer:clock=200 --set zeusminer:chips=1
With a power use of 5W it might be hard to run full speed on a USB2 port. An externally powered USB hub is probably a must.
According to the
descriptions here, running at speeds over 200kH/s requires an extra fan.
Linux tip: if you're under Linux, like me, you need to have the right permissions set to communicate with the ports. I also have a few different USB miners; Antminer, Moonlander, and now Zeusminer; that use the same communication chip. Doing a
--scan all, or even
--scan zeusminer:all on these, upsets some of them. To fix this, I run some
udev rules to set a new permission group (that my user belongs to) on the USB ports, and create logical links to the ports. That way solving the permission problems, and being able to scan them by name rather than USBn (where 'n' obviously changes depending on what order the devices respond/are plugged in.) So now I can do
--scan zeusminer@/dev/crypto-mining/zeusminer-0 and
--scan MLD@/dev/crypto-mining/moonlander-0. No risk of hitting the ASICs with the wrong driver! My ASICs are a lot happier after that.
I hope this helps someone. Happy mining!
