wrong question
wrong understanding !
standards refer to devices and computer ports/ hub, not cable compliant
rather let's simplify
usb 1.0 / usb 2.0 port on computer
usb 1.0 / usb 2.0 on device
i've posted a whole lot of bla-bla, now can u plz. be specific bout u'r question !
Universal Serial Bus (USB) is a serial bus standard to interface devices. It was designed for computers such as PCs and the Apple Macintosh, but its popularity has prompted it to also become commonplace on video game consoles, PDAs, cellphones; and even devices such as televisions and home stereo equipment (e.g., mp3 players), and portable memory devices.
Version history
USB 1.0 FDR: Released in November 1995.
USB 1.0: Released in January 1996.
USB 1.1: Released in September 1998.
USB 2.0: Released in April 2000. The major feature of this standard was the addition of high-speed mode. This is the current revision.
USB 2.0: Revised in December 2002. Added three speed distinctions to this standard, allowing all devices to be USB 2.0 compliant even if they were previously considered only 1.1 or 1.0 compliant. This makes the backwards compatibility explicit, but it becomes more difficult to determine a device's throughput without seeing the symbol. As an example, a computer's port could be incapable of USB 2.0's hi-speed fast transfer rates, but still claim USB 2.0 compliance (since it supports some of USB 2.0).
Any cable with a receptacle or with two “A” or two “B” connectors is, by definition, not USB. However, many cable manufacturers make and sell USB-compatible (yet not strictly conforming) extension cables with a Standard-A plug on one end and Standard-A receptacle on one end.
Note that only “full-speed” and “high-speed” devices use detachable cables. "Low-speed" devices only use captive cables because the low-speed specification does not allow for the electrical characteristics of standard detachable USB cables.

USB 2.0 is critically quicker than the previous version. Cables categorized 2.0 compliant are qualified to assist the better speeds. Older cables will nonetheless artwork, yet won't attain desirable speeds for 2.0 (which you will no longer observe besides). you will detect extra info than you may ever opt to understand on USB on the hyperlink below.

In order to use a USB 2.0 device, which is a lot faster than a 1.0 device, you need a cable specifically rated to handle the extra speed.

the only difference between the two is that of the data transfer speed.. in usb 1.0 the max. data transfer speed is 11mbps where as in usb 2.0 max. data tranfter is 480mbps.
usb 2.0 is around 40 times faster than usb 1.0 . if using windows xp, u need service pack 2 installed , if want to use usb 2.0 drivers.

A usb 2.0 should be compatible with both since it's the latest version. 1.0 probably won't work with 2.0 devices.

USB 2.0 transfers data a lot faster... doesn't matter for a mouse or a keyboard but matters for an mp3 player, for example

friend both of thm r for same purpose but the only differnce is 2.0 has more data transfer rate thn 1.0 this is the only difference.

USB 1.0 IS SLOWER THAN USB 2.0, THATS ALL IT IS!!!

Hi. They are interchangeable, I think, as each has four conductors. 2.0 is much faster, of course. I'm not sure.
