Just to add device-spesific info (because this thread is coming up on google search still)
I have been using the said device for 2 months straight now.
Bought it on aliexpress for 16USD

It is a 8Gigabyte usb flash disc, containing files and drivers necessary.

The miner part is 200 kh/s Scrypt miner (advertised speed is 144kh/s, works solid given correct parametres with cgminer 3.1.1)
Couldn't get it to work at 280kh/s though, this is my search criteria, which got me to this thread in the first place.

at 200kh/s it currently generates about 0,001 LTC / day at my preferred pool
So it will take years to get back the money i paid.

anyway, it is just for fun & research
