All my dear friend how can I extend my USB cable 30FEET(=9meter)?
I usually want to drive a web cam. I tried with telephone cable but my cam hang after running sometime.

Please help me.
 

Re: USB cable extention

By specification, USB cable segments can have a maximum length of 5 m, and have a 90 ohm differential impedance, different from telephone cable. Unless you try to overstretch the specification, you can use up to four 5 m extension cables with built-in repeater (a one port hub) plus one passive 5m cable.
 

Re: USB cable extention

More than 5 m doesn't work without special devices in the middle of the cable, you can buy them at a computer store.
