I have a Wacom Bamboo tablet. I installed Wacom drivers, and Wacom dock. Now I can use both the pen and touch, but there is no pressure sensivity when using the pen (I tried using it in Photoshop). Is there a tool to diagnose the pressure?
In the Wacom settings panel System Preferences - Wacom you can adjust the pressure sensitivity by clicking the pen in the Tool panel.

In Photoshop (CS 4 and above) you have to set your brush sizing to pen pressure:
The screenshots from above are for an Intuos 4 but they should be very similar for the Bamboo Pen.
If your not getting any sensitivity send an email to Wacom support. They are very helpful and responded quickly with instructions on how to fix a problem I was having with Illustrator crashes.
