user33172: I'm talking about hardware such as USB miners, etc. I'm asking, because I see people mine with 86kH/s on my pool…

user31844: From here

CryptoNight is a proof-of-work algorithm that mixes graphics processing unit (GPU) and central processing unit (CPU) mining to create a system resistant to both application-specific integrated circuits (ASICs) and fast memory-on-chip devices.

So, there is no dedicated ASIC hardware (yet). You can currently only use CPU plus GPU (which of course counts as hardware but I assumed you meant dedicated to mining hardware like ASICs).
