Doggie or someone who maybe have the experience... i got today one Zeus Blizzard to try it. It is possible to make it work in the same computer with the R-Box without problem? i dont want to make the test without getting some advice first

I have the experience

You can run the rbox with bfgminer and the blizzard under cgminer, the only thing you need to do is mapping the ports properly with these strings , for rbox (bfgminer) -> -S rockminer:\\.\com* and for blizzard (cgminer) -> -S/./COM* , where * it's the number of port.
Got one small question...
I install for the CGMiner and Zeus the CP210xVCP. What should i install for the BFGMiner and RockMiner? It is not in the OP only this
**If you have previously installed drivers using Zadig as above, you will need to reverse this to use BFGMiner**.
I will do all this it in a new machine so i dont have it installed there... the CP210xVCP works also with the RockMiner?
