"...how can i conncect the wires to have (Live View) Video...."
 
....i only want to use a single video cable. i dont need audio....

i want the easiest connection . dont care if i have only liveview and usb remote
Just guessing about this (EXT-USB-B 11pin Connector) stuff below:-
Ref :- HTC ExtUSB 11 Pin USB Connector with a Breakout (PCB)
here (but now retired) https://www.sparkfun.com/products/retired/9167 or it was also available  on ebay .
(Wrong)****Pinout:-
• 1: USB VCC +5v (= Ok)
• 2: USB Data -    (= Ok)
• 3: USB Data +   (= Ok)
• 4: N / C            (= Ok)
• 5: USB GND      (= Ok)
• 6: Left Audio +
• 7: Labeled “AG”
• 8: Audio - (GND) Labeled “CK”
• 9: Switch (Talk) Labeled “OT”
• 10: Right Audio +
• 11: Mic +
• 12: Chassis Ground (GND/Sheild)

The correct pin outs (for, Live View, Video (???)) are here
Ref:- http://www.achillies.com/CHDK_Files/USB_Splitter.htm

"...Here are the pinouts for the Canon AVC-DC400ST Video/Audio cable. and the colours on the splitter to connect them to..."

11  GRND (vid/aud -) –  (Red wire on our connector.)
10  Composite Video +  (Purple wire on our connector.)
9   Left (white) Audio + (Orange wire on our connector.)
8   Right (red) Audio +  (Yellow wire on our connector.)
7   N/C -
6   GRND (vid/aud - ) Video out enable. ( If connected to blue wire on our connector, video is output via cable.
May put switch to change between LCD and video output)

On the standard Canon audio/video cable, pins 6 and 11 (red and blue) seem to be tied together.
This causes the camera to start outputting video and audio any time the cable is plugged in.
You can put a switch between pin 6 (blue wire) and ground and be able to switch from video output via cable to LCD display without unplugging the cable.

i just cant understand 2 things.
first why it works only with usb hub (which has led ) , plug in usb-b cable camera ,plug 11 pins extusb ?
second why with this usb hub i can trigger both cameras without sync from chdk ?
