There was a big cybersecurity story in 2017 or 2018 that china had been back dooring nearly every piece of hardware coming into the US. There was big talk about completely banning Chinese hardware at that point but nothing every happened. 

Theoretically, any hardware can be utilized for surveillance if sufficiently engineered to do so in non obvious way. So, if the White House wanted to try to ban any hardware that could be used for surveillance, it’d basically cripple the entire economy. Otherwise, if they tried to single out mining hardware, I feel that would be a relatively easy lawsuit for singling out the industry.
