Antminer S3 doesn't have anything using USB.

I thought the LAN adapter was USB.

but even if its a lan adaptor I have access to the webgui and I also tried a hard reset
and other miners does not have this usb error..

I exchange the controller board with another miner and the problem follow the controller..

Have you considered just replacing it with an S5? Given how cheap the S5's are now, considerably higher hashrate-efficiency, etc.  I personally wouldn't be willing to invest any time in diagnosing or replacing parts on an S3.  Even with free electricity, you are better off with S5's.  Just my opinion before you invest too much time/money into it.

if I have to invest money on it I will keep it for parts.. I use it just to heat my house.. using this and a wood stove when too cold..
