Cables that I have bought recently from brand-name sources have a logo that looks like the middle logo at the top of the page: http://www.usb.org/about/faq/ I would trust such cables to be fully compliant. What you say (the faq says) below is true, but how do you know if you bought "fully compliant original USB cables" when you bought cables way back when? Do you still have the product literature? . . . Simple physics says that physical cable construction is important for useful bandwidth. Try the old cable and see what happens. You may be all right. Testing will take you some time.
The logo is on a piece of label "paper" (plastic, foil, etc.) that is wrapped around the cable and sticks to itself such that it "wings out" from the cable. Cables that come with a product such as a hub should be compliant, but generally don't have the label. All this is just observed practice. Fred Holmes At 09:33 PM 2/28/2008, Tom Piwowar wrote: >>Yes.
