Pro Flight Yoke Jumpy and Erratic

[aharwin]

My Pro Flight Yoke has become hyper sensitive.
It no longer behaves smoothly with respect to pitch and bank.
All inputs result in extreme movement of the control surfaces and
makes the aircraft impossible to handle. I have re-installed the driver,
gone through calibration, set sensitivities and nulls to the recommended
settings. Nothing seems to help. Running FS2004 on an XP machine.
This has just started happening. Any answers?

My yoke has a severe jitter! In the cockpit pictures, the aircraft yoke/joystick moves erratically, the ailerons move, too when using outside camera.
I tried several USB ports in my PC, no success.
Can anyone help?
