Strange Laptop Speaker(??) Noise Interference ?

[slickcondo]

If they were in use at the same time and something happened ...they yes, in theory they could have died at the same time... Do you really need to connect 8 USB devices in at the same time?

Hopefully the hubs have their own power supply and aren't all using the power from the mobo.

Ooops ! Yes, they were both in use at the same time. I split their use between them as follows:

Hub A: USB Modem, USB Webcam*(pointing out toward the front of house), and USB Mouse

HUB B: USB External Hard Drive, USB Webcam* (next to the laptop), and USB Keyboard

*NOTE: two webcam hooked up, but only one in use at any one time. But both are connected so that I can change to either webcam.

Question: If I connnect Hub B to Hub A, will that work or will it gave erratic performance ? I tried it twice and at boot up, sometimes it works and sometimes it hangs at the "Welcome to Windows" page. I was wondering if this was just a one of those one off thing or becuase the Hubs were connected in series.

But if I connect the first Hub which is a USB2 Hub to the laptop and a USB1 Hub to the USB2 Hub, it seems to work ok.

Any thoughts on this ?

Oh by the way, both Hubs were powered by the laptop USB port.
