I am working with a robot that uses USB (not by choice lol) in a very static-prone environment, and I'm having problems with ESD locking up my USB hub. I found an "Industrial" USB hub that claims it can withstand a 15kV shock through air and an 8kV direct contact shock. I'm wondering what the effectiveness of that would be as compared to using USB Surge Protectors inline between a standard USB hub and the slave/master devices? What about using both at the same time? Would that actually help at all, or just introduce weird problems due to capacitance and whatnot?
Edit: I should mention that non-COTS PnP solutions are not an option unfortunately (for example I can't solder a special ESD protection chip to the data lines)
