•Software: I-Catcher Console 3.3
•Cameras 01, 02, & 03 are USB 2.0 A4 Tech webcams. "logi" is for the C500 Logitech (also USB 2.0)

I don't remember the sequence but the following was done before I could get them to work:
•Used 500W PSU.
•Updated USB 2.0 drivers for PC.
•Updated to WinXP SP3.
===
What I found out:
•300W PSU isn't enough to power up all devices.
•I can use 2 webcams on a yard long USB extension hub.
•None of my A4 Tech webcams work properly on USB 2.0 extensions (I used one 2 meters and another, 5 meters.) If they did work, FPS would be like 0.10 or 1 frame every ten seconds.
•My Logitech C500 worked well with my USB 2.0 extensions cables.

The reason I got into this is because I was challenged by my peers to come up with a cheap surveillance setup.
Hope the input helps.
