cables specs for USB2?

[JB]

I need to make some extension cables up for some USB2 devices in our lab but
I'm not sure of the minimum specs for the cable.
Any help much appreciated.
Thanks,
JB

I think USB2 is spec'ed for 5 meters. I wouldn't recommend estensions - but
rather long cables....

I was going to use flying leads of 4M-5M for the devices. I didn't want to

use extensions if I could help it, but needed the cable specs so I could fit
my own 'made-up' leads.

cheers,

The easy and probably cheapest way is to simply buy a few 5m extension cables,
and chop off the ends.

The official USB2.0 specifications can be downloaded from here:

http://www.usb.org/developers/docs/

Included in the specifications are guidelines for the cables. Good luck.
You would probably be better off just buying the cables you need rather than
trying to make your own. Real engineering goes into making USB cables, it
isn't just a matter of making the proper electrical connections like with
RS232.
