Bug Description

I have a gamepad (detected as: ID 0e8f:0012 GreenAsia Inc. USB Wireless 2.4GHz Gamepad) which is actually no wireless.
After running the calibration process, the retrieved range for each axis is as follows:
minimum = 0, center = 12, maximum = 128.
As you can see, having the center at 12 doesn't make sense and leaves the joystick working badly:
* Values jump up to the maximum really quickly when moving the sticks to the left and/or up.
* Values work fine (smooth changes) when moving the stick down or to the right.
The gamepad works fine under windows 7, and it displays raw data during calibration as follows:
minimum = 0, center = 128, maximum = 248
