as far as i can tell its just for all practical purposes nothing but the price ...... there is some technical mumbo jumbo ....(see below) but unless your cable runs are reaching toward maximum....why bother???
"The maximum length of a standard USB cable is 5.0 meters (16.4 ft). The primary reason for this limit is the maximum allowed round-trip delay of about 1500 ns. If a USB device does not answer to host commands within the allowed time, the host considers the command to be lost. When USB device response time, delays from using the maximum number of hubs and delays from cables connecting the hubs, host and device are summed, the maximum delay caused by a single cable turns out to be 26 ns [10]. The USB 2.0 specification states that the cable delay must be less than 5.2 ns per meter, which means that maximum length USB cable is 5 meters long. However, this is also very close to the maximum possible length when using a standard copper cable."
from wikipedia
The difference between USB1 and USB 2 is that the USB 2 is shielded (like TV coaxial cable) to prevent signal loss between computer and printer. Look for a printer cable that is clear with the shielding visible.
USB 2.0 is the newest one!!
usb 2 can sense a usb 1 and down shift to the slower speed
usb 3.0 is the newest (or maybe that was last month) and can downshift to USB 2 or usb 1
(edit) usb3.0 was introduced in 2008
to answer the question i dont know of any difference in the cables
usb +5v -0V 50' may be max
rs 232 is good at perhaps 500' +-15v
rs422 is good at a mile +-20 miliamps
Buddy, USB's are used to transmit signals serially. 'Cos of their multi usages, it became UNIVERSAL. The 'BUS' in the name connotes the transmission. USB 2 came out of the blue with speed promises (transmitting large signals from one medium to another fast) over USB 1 (the original). It can be observed that cabling is thicker in USB 2 than its predecessor. Verdict: comparatively, USB 2 should transmit the same load (signal) faster than USB 1. This is true with USB 3 cabling - it's thicker than USB 2. Thank you [niiadebolo@Yahoo.com]
There is no physical or electrical difference between USB 1.1 and USB 2.0 connectors.
usb 2.0 having speed of 480mbps & usb 3.0 has 3to5gbps
USB 2.0 is so much faster
The difference between 20 degrees and -30 degrees is 50 degrees. This is because you subtract the smaller value (-30) from the larger value (20) to find the difference. Mathematically, 20 - (-30) = 50.
30
49
-10 degrees
30
It is: 29-23 = 6
29 - 23 = 6
The question does not make sense since 20 and 30 are not prime numbers!
The average equals 30. So 10
The Difference of math is when you subtract 2 numbers and get the number between it. Example: 30 -20 _____ 10 The difference there would be 10.
600 - 150 = 450
The difference between 20 degrees Celsius and 50 degrees Celsius is 30 degrees.
