Photoshop CS6 Brush/Pencil tool not working correctly

[TWTgames]

I bought a drawing pad today (TRUST Flex Design Tablet Black) and I want to draw with it on Adobe Photoshop CS6, but when I use the brush tool, it only makes straight lines and sometimes they are too thin to see, but that depends on how hard and for how long I press on the mat. If I press really quick and hard, I'll get a straight thick line, but thats not how I want it. Can anyone help me with finding a solution to this?
