I'm glad to confirm that occasionally bought HP webcam HD 2300 is compatible with Linux Ubuntu 10.04 and 12.04. The webcam design is perfect IMHO, the price in Europe (France) is moderate (about 25 euros on retailers like Darty). Good news to linux users.
For testing webcam install and run cheese program sudo apt-get install cheese
