All depends on your definition of quality. There are no "good" USB
cameras; there are satisfactory cameras that are OK more or less for
videoconferencing. If you plan to shoot Star Wars, it won't be good
enough.

The best USB cameras are ones made by Philips, in no small part because
the driver for those cameras was written with specs in hand.

In most cases, you will get 320x240 image with 15-20 fps. Some cameras
have 640x480 sensor, but then the frame rate drops to 1-2 per second. Some
cameras have compression, this improves fps and lowers quality. Color
resolution is very low in most cameras (because of cheap sensors). Cameras
themselves routinely are sold for $25-30; you simply can't afford any
quality parts at that price. These cameras are "consumer devices", not
professional ones - meaning that they are mostly toys.

Again, all depends on what you want. USB webcams are suitable at most for
low-end videoconferencing, where postal stamp - sized image is all you
want, and all you care to transmit. If you need better quality, you won't
find it in the webcam land.

See http://www.linux-usb.org/ to find a supported device before you buy.
