Device Cable
What is the longest distance i can run a usb cable to a device with outside power?
I am working on a home automation system using some homemade usb devices and a just curious how far I can use a device. the will not be powered from my computer.
If you need to run longer distances you can try USB extenders. This one will give you up to 150ft over cat5 or cat6 cable.

Usb and Scart Cables
A lot of technology is going into our televisions and computers nowadays, but what we do not know is that a lot of technology and innovation went into the leads, cables and plugs on those items.
USB cables, SCART leads, SCART cables and AVI cables are among those little things that are so vital to those devices and enable them to work.
SCART leads are widely used throughout Europe and are actually the most common connection between audio visual equipments. SCART cables and connectors first appeared on television sets at the end of the seventies and first became compulsory in France a couple of years later. A SCART lead has twenty one pins which actually help improve the quality of the connection and sound or image coming out of the device. You can even get SCART cables with gold plated plugs for better sound and image quality.
However, SCART leads can not carry S-video and RGB signals at the same time which can be a problem on some devices. On top of that, the loss of connection due to a loose connector is something very common mainly because the cable used is very thick and heavy.
Another very common item is the USB cable and its port. This device created in the middle of the nineties is also very common on games consoles, computers, mp3 players and other devices. The Universal Serial Bus (USB) was first made to answer the need of having more than one peripheral connected and disconnected quickly without having for example to reboot your computer or to turn off the device each time you wanted to connect or disconnect it. Whereas the first USB cables were introduced as USB 1.0 in the nineties, you can now find USB 3.0 which was released at the end of two thousand and eight with new specification that allow the user to have a transfer rate of nearly ten times faster than the USB 2.0 version, which is quite amazing.
There are so many different types of cables though and USB cables and SCART cables are probably among the most commonly used.
In the end, there is so much technology in our different devices that we even forget that even the connectors used to plug those devices together also are full of technology as well. It is also very easy to buy those kinds of cables and leads online or in shops.
