I can tell you I have a USB2 cable and I have seen USB1 cables at Dickies,so the answer is,you do indeed need one or the other.

457575 2006-05-25 10:55:00 I will defer to Cicero's superior knowledge here, but USB 2.0 shouldn't require you to buy new USB cables necessarily, unless you have really cheap cables or long cables.

Certified USB 2.0 cables are indeed available and preferred, but they're usually just high-quality USB 1.1 cables apparently. (Confirmed on Google)

Thats a strange way of deferring .

One should always strive to be a little strange when responding to a Cicero post, in the interests of consistency, in my view. I do try to conform to expectations, hope you appreciate it.

One appreciates the admission of strangeness,well done.

457580 2006-05-26 05:49:00 My understanding is that USB 2.0 cables are specified to have larger conductors in the DC pair, and better controlled impedance (and also slightly larger wire) in the twisted pair data lines. (You can often see the wire gauges printed on the sheath. Smaller numbers are bigger wires: e.g. 24 AWG is bigger than 26 AWG. Look for 24 AWG or bigger for prefernece).

Good USB 1.1 cables will be fine. Most short USB 1.1 cables will probably be OK. Bad USB 2.0 cables won't be. "Good" and "Expensive" aren't necessarily correlated.

Try the cables you've got. If you need to buy new ones, you'll probably find only 2.0 in shops, but check.
