Dear. I'm trying to connect to a Gawminer Falcon, when connected throws many HW. I am using W7 32 bit, sgminer 3.1.1, the .bat file is written:
sgminer -o stratum+tcp://scrypt.usa.nicehash.com:3333 -u YOUR_BITCOIN_ADDRESS -p x --nocheck-golden-count --chips --ltc-clk 128 -S 328 //./COM3
What is wrong?

Try to adjust difficulty with password parameter. Please see this faq:
