Thanks to 7 queue for the most awsome S1 binary in the world. Full production on 80 S1's on P2Pool with BETTER than expected results of only 2.1% DOA and 118.3% Efficiency and finding shares at an incredible pace.

Many thanks for Nicehash for finding someone as talented as 7 queue for the binary.... I have tested all 80 S1's on Westhash over nite and the overall DOA used to be almost 1 TH/s rejected and it's cut in just about 3/4 of that.

Now.... How about some love for the S2??? Seems that's the only issue I am having with Nicehash now, with the S2's running the up to date firmware and --queue 0, which works perfectly on P2Pool now, but consistently refreshes and resets beteen 25, 30, 24, 45 seconds. 

The USB_ID is sent from the MCU via Pin 41 to the USB controller which in turn basically the UARTS are technically two USB ports just with a couple extra things as temp and fan control.
Pins 3 RX and 5 TX on the UART with Pin 1 being Fan/Power Management and Pin 4 being ground, 6 and 7 being temperature control pin 8 is ground. So with all this mind the UART plays a dual function, hosting the USB/Power and then the temperature control settings.

The USB chipset I do believe you are looking for is http://am.renesas.com/products/soc/usb_assp/product/upd720114/index.jsp I sure hope this helps you out as I am dying to get rid of the POS bitmain version of cgminer on my S1's....
