I had a problem similar to yours, and discovered a problem similar to Toad.
I have an HP Officejet Printer/Fax machine. When my computer was turned off, the printer would leak voltage back into my system and this would screw up my CH joystick/Prothrottle combo. My fix was, when this happened, to shut off the computer for a minute, push buttons on the throttle a few times, power back up and everything would be fine.
This was only a slight inconvience, not all the time, and was fixed when I built a new computer with an ASUS motherboard. I didnt build it to fix the problem, rather I was just due a new computer.
I have worked with CH support several times, they have been great at helping me. They have sent me spare parts "just in case", exchanged my throttle when I was having the problems described, fixed my joystick, all without cost to me.
My opinion = I love my CH hardware, have had great support and would recommend it strongly.
I hope you find out what is causing your problems soon, I know the frustrations.
