I wouldn't want to help someone with such a negative/attacking attitude.

I don't even care if my comments are false, as you can clearly see, I am new here, and being so harsh, and attacking with new people is a bit much dude.

Even if all I said was bad, then just try to correct me, instead of blatantly attacking me (in a general way too, saying its all completely false)
 Even still, you failed to mention any solution, you say switch to linux, or use cgminer(which uses 75% of cpu also)
So exactly .....WHAT solutions do you present, if rpcminer isn't the ONLY viable cuda miner.

You say that cgminer dosen't attack all FTDI ports constantly?
Did one version of the code DO this at one point in the past?  

After looking into it, looks like the ufasoft code is the culprit here..  sorry...


So its actually ufasoft(ufasoft_0.37) that is abusing the ports..  my bad..
I thought it was cgminer, my bad.

I thought I WAS running cgminer, but I must have switched to ufasoft at some point.

I also am not much help, I do hardware/firmware development, I try to stay away from the software side of it if I can.
But if someone wants to send me a fpga/asic dev board, id be glad to help.      
WHOLY CRAP ARE High speed FPGA/ASIC's expensive. (even if you just buy 1, bga ONLY, not even on a pcb)

Stratix IV fpga =  Cheapest single chip is $1,000.   FOR ONE CHIP.

(but I do dig into software code when I MUST, to help determine if bugs are software or hardware.)
