Simulation on what? Judging from the ICA 0 driver used and hashrate it looks like an Asicminer Block Erupter USB...?
It certainly does look like an ASICMiner USB Block Erupter. Curious.

this may be true or not, but the matter is another: if this is a pic of block erupter usb stick or some of their prototypes!
