USB 1.0 & 2.0

[[email protected]]

[FONT=Georgia][SIZE=7] I have a number of USB cords, Is there a simple way to tell the defference between the 1.0 & 2.0 cords, and is this a big defference if using a 2.0 hub & a 2.0 device. I know of course that the 2.0 is to carry faster, but looking for a way to tell the cords apart, then I can label them. Much, Much thanks

In theory usb 2.0 cables ought to carry this logo

Using usb 1.0 cables with a 2.0 device can/will result in 'unexpected weirdness' or nothing at all or just slower !

I've found the best way to sort this confus-ed-ness, is by testing ... I use a usb 2.0 external hard drive with a known good usb 2.0 setup & then try my cables, clocking the speeds ...
