USB Extension does not work with new computer
I have been using a USB extension to hook up my USB modem to the old Pentium III. Worked fine for ages. But now whenever I connect any device to that extension (on a Core2Quad), the device remains unrecognized. Is it some kinda USB 1.1/2.0 clash? Please explain, (as if to an illiterate?)

What do you mean by "extension"? A cable extender? A USB hub? Both?

Cable extender. With a female port on one end and the male one at the other.

There's a joke here, but I'm not going there...

If the device is USB 2.0 as is the port on your new system, then they will try to communicate at USB 2.0 speeds (up to 480mbps) as compared to USB 1.1 speeds of the old system (11mbps). In such a case, if the extension cord is not USB 2.0 rated, it might behave as you have experienced. I would suggest trying to connect the modem directly to the computer's USB port to see if that works. If it does, then you know that you need to get a better extension cable.
The other possibility is that since the modem is likely USB powered, the port you are using doesn't have enough juice to power the modem. Try another port if available.Sometimes, real fast is almost as good as real time.

Well, everything of mine (including the modem) works fine. I only have trouble with that extension. So I accept, it would be a 2.0-1.1 clash. Rubberman, post up the joke here, if its filthy, then PM me.
Neither do they help.This is exactly what I thought. If it's a front mounted port it's likely unable to power the cable or devices over that longer cable. Try one of the ports on the motherboard at the back."When you have nothing to say, say nothing."

Not filthy, just a bit salacious...Cable extender. With a female port on one end and the male one at the other.
Joke: what has a female port on one end and a male on the other, and could be considered "an extender"?
Sorry, but I have a dirty mind.

Hope no one ever comes back to this page again, or I am gone.
