      Hi,
     
      I make some tests. Theoretical limit is 5m per segment for  a maximum of 5 segments.
      Practically, using STP cable I get reliable connection even at 10m. It is possible to get even more.
      You can use the 8 wire like that:
      - 4 for the standard usb pins
      - 2 for power supply GND
      - 2 for  +5V for the powered hub.
      Take care that it is possible not to be able to use 2 webcams on the same USB hub. Usually, one cam request aprox. 75% of the bandwidth.
     
     
      BR,
      Dan
     
      P.S. This is what I use in this moment.
      I will post in a couple of days, on my site (http://www.geocities.com/tdanro) a small application to select one of the AV source connected to a Windows Media Encoder remotely, when not home.
      Is very usefull for surveillance purpose.
