Is there a difference between USB and USB2 cables?

  prb 13:40 05 Jan 2006


I'm looking to but a new printer which has a USB2 interface (as does the PC). My question is if I use my old USB printer cable will I suffer any loss of speed etc? I notice that some places actually advertise USB2 cables... but surely it's simply a case of connecting terminal a on computer to terminal A on printer so the old cable should do the job?!?

The USB cable will work but it wont give you USB 2 speeds thats the difference.

On the other hand I once looked into this and asked a cable manufacturer what the difference was and what specification a cable had to meet to be classified as USB2, they didn't know.
I've never detected any speed difference using so called USB 1 cables on USB 2 peripherals.

If anybody can post a link to any applicable page specifying cable standards, I'd still like to see it.

Apparently there is no special spec for a USB2 cable. A problem can arise however, in that many USB1 cables were built below spec, and functioned fine for USB1 - but will not function with USB2.

Common problems are - lack of shielding - and too thin a quality wire being used.

So basically if a cable works OK with USB2 then it is OK. But many really cheaply built ones may not - or worse may not work consistently well.

The moral of the story seems to be - buy USB2 specified cables that have the *Hi-Speed USB* logo on them, if you want to be a happy bunny.

I've e-mailed USB-IF to see what they have to say. Either way unless it's a mind bendingly rapid industrial laser printer, it's probably not going to show much benefit from having USB2.

Electrons travel at the same speed whether USB or USB2. Connectors and fittings are the same for both. The cable in between would have to be extremely poor quality (falling apart?) for any difference to be noticed. Don't be taken in by marketing hype.

Thanks everyone for your help - think I'll try the old cable first... although at £2.68 @ Amazon it may well be worth just getting a new cable.

€dstowe is 100% right.
