This MAY be for use with a special device that has a USB port on it which INTERFACES with your computer, but THIS IS NOT FOR PLUGGING UP TO YOUR COMPUTER.
***** >>>>>>> DO NOT PLUG TO YOUR COMPUTER <<<<<<<<< *******
Do not be fooled by the little "box" in the middle of the cable which some might believe is an analog-composite-video-signal to digital-serial converter. It is not.
I disassembled the cable to see what it was, and it is merely 3 RCA connectors going to the USB port. That's all! This can damage your USB port and/or the audio/video device you plug it into. Here's why, and here is the PINOUT of the cable:
* The ground of the RCA connectors is also the ground of the USB port as well as the Data ground (D-) on the USB port!
* The "Right Audio" composite pin is actually the +5 Vcc on the USB port! This will inject 5 volts into your video/audio device if plugged in!!
* The "Left Audio" and "Video" composite pins go to the Data positive (D+) on the USB port!
Again YOU WILL FRY YOUR USB PORT AND/OR YOUR VIDEO DEVICE if you plug this cable in and connect it up. 3 RCA to USB Cable
It is absolutely an amazing deal, just perfect for watching vhs tapes or dvd's on your monitor (which is what I am using it for)FREE SHIPPING is another nice perk. Whatever you are using this converter for it is worth it(exept if you are trying to use it to connect your laptop to your tv because its only supposed to be able to input not output) So don't listen to all the reviews that say this is a horrible product because it didn't connect their laptop to their tv. Great product, Great deal, and Great seller!
the reason you can't use it for connecting laptop to tv is because of the direction of travel of the information. your laptop's video OUTPUT does not go through the usb ports, it will go through either and s-video connection or a serial port. this cable is for input to laptop, not output from it. so connect dvd player, vcr, camcorder, etc. and you're fine. so, yes, the people who are complaining about not being able to use to connect to tv's are indeed foolish, know what you're doing, people, do some research first. if and only if your tv has rca outputs, which most do not nowadays, then you could use it to record what's on tv, but easier just to connect to your cable box or dvd player or something. - Computer Cables - Rca Cables - No Good - Junk'
