Here's a weird one I don't understand. Maybe somebody can help me understand
what is going on.

I've been goofing around with a Logitech QuckCam I got a while ago "free" from
comcast. It's well supported by Linux, although anything but great image
quality.

Anyway,the darn thing wouldn't work and I finally figured out that it was
because it was being hooked up through a USB hub. If I plugged it directly
into my computer, it worked fine (well, as good as it ever would). If I
plugged it into a hub, it would not produce an image.

lsusb sees it through the hub, but I couldn't get xawtv to pull an image from
it.

I duplicated the problem with another hub, and got the same result. One of
the hubs was powered, one was static.

Can anybody explain this? I'd like to use it through a hub (much cleaner
wiring), but I don't even know what type of hub (if any) I should buy to make
it work.

Any comments, prognostications, disertations, or suggestions would be very
much appreciated.
