USB Cable Extension

Five days ago i bought a cable for USB Extension. I haven't been able to try it out until yesterday and i found out it was broken, since my USB couldn't be detected at all. I was using Slackware Linux on my office and i never thought it was Linux's fault. So i tried to test it on my colleague's laptop who's using Macintosh and Windows and they ended with the same result: the USB wasn't recognized.

Today i went back to the computer store and ask for replacement. They said that cables doesn't have warranty. I told them that in the receipt i got, every item which has low prices are guaranteed for two weeks. So she said that they will replace it, but only once and it will be a shorter cable. I said OK, so we agreed. Since it's only one time replacement, i went to the neighbor of this store which is a sub division for services. I asked them to try the new one and it failed. They gave a replacement and let me tried it but everything failed. I got a replacement three times, until finally they gave a better cable for me (i think they grab it from other product) and it was more expensive than mine, but it's definitely shorter, but it works (finally). So i decided to take those without any charges at all. It's a black one, similar with my computer's casing on my office.

Here's the result from Linux's dmesg:

USB 3.0

This year, we will have a new faster peripheral connection by the availability of USB 3.0, peripheral interconnect technology that has been used by every users around the world. USB 3.0 is set to deliver a data transfer rate of up to 4.8Gbps - ten times today's 480Mbps USB 2.0 data rate - and introduce optical interconnects to the bus. The goal, the companies behind the specification said, is to create a version of the bus that's able to deliver files of 25GB or more (that's quite ambitious, but i believe it's common thinking, since multimedia files are being common thing and it's growing all the time).

The third version will have it's own name, called SuperSpeed USB and it will be backward compatible with the previous 1.1 and 2.0 version

There will be two connectors for the USB 3.0 devices, electrical and optical. You can look for the images below. The first one is the electrical and the second one (smaller) is the optical version. The third picture will show the diagram why it would be backward compatible with the previous version.
