I just found these on ebay:

Right now i just use a single graphics card and wanted to do more mining. I would buy a mining rig only i have very limited cash right now and these look really cheap.
Are they any good? and how would they work exactly? I quess you just plug it into a PCs USB slot and mining software should detect them and use them?
There was a Bitcoin one also but i am guessing that would be way too hard to mine now unless you had a huge pro mining rig.

They won't make you any money; they're based off of very old zeushash chips over clocked to where they are in the miner. Cooling is also an issue with them, and some users have reported it hard to find software that actually reads the miners. The U2 won't make you anything either; the days of usb bitcoin and scrypt mining are over. http://www.ebay.co.uk/itm/usb-Dogecoi-ltc-Litecoin-Miner-mining-ASIC-USB-All-SCRYPT-Coins-Virtual-Currency-/282161519720
