    Which is VCC and GND in this USB cable?


    I am trying to create cooler pad for my laptop. I have 3 5Volt fans. I pulled out two usb cables from old keyboard and a mouse. Things are different here. I heard it would be Red, White, Green, Black will be inside.
    But what I got from both is this. I see no black. but a blue one.

    Its from Intex Usb Keyboard and Mouse bought in India. I tried using my skin(i have no multimeter), Red Green and Blue show some power. But white is dumb. I think white is GND.

    Got it. Blue VCC, Red GND.
    Tried connecting all cables randomly to fan. And found the working combination.

If I tape together tightly HDMI and USB cables for a 15 foot run, will they cause any interference? I know they are digital signals so I think should not. But doing this does cause a herring bone interference with analog vga cable.
Getting a new TV and placing it in a different spot than where the old TV is and I realized the coaxial cable coming from the wall isn't going to reach the new location for cable box's "Cable IN" connection. Can I use this as an extension? It looks right to me but I just want to be sure.
