They just started doing. Tired installing the drivers again and it went away then started again. Go to CP and it doesn't work. If I unplug and plug back in it stops flashing and works again. This is JUST the joystick lights NOT the throttle lights.

Any ideas? Running latest software.

could be low output from USB port/bad connector between js & throttle?

Unistalled did a reg clean reinstalled, had to find two files saiho255.sys and and a sai dll file but both were in my system32 directory, so far so good. Saitek site had said to return it for being defective but I had a suspician it was a softare problem.
