Hi All...I built a twin throttle quadrant by using 2 CH Yokes and their pots. Initially when I set everything up it worked fine in FS and the Windows setting control panel recognized them etc...After a 2 month lay-off I went to try and use it again but for some reason Windows only recognizes 1 USB in the settings/control panel/gaming options. I see 2 USB options in window but when I click on one of them it doesn't stay on it and jumps down to the other one...thus I only have one set of pots working on Flight sim...Don't know what's happening. If anyone has any ideas I would certainly appreciate your help...many thanks...JB

Sounds to me like the second USB device is constantly re-enumerating. Check and make sure your USB plug is firmly plugged in.Have you tried cleaning your system of all USB devices / drivers and re-installing them one at a time? That's fixed things for me in the past with other strange behaviours on my system.Lastly, the USB chip might have reached its expiry date and CH wants you to buy a new Yoke perhaps...Cheers,-Leo

Thanks Leo..how do you clean the system of USB drivers ? Where do I find them ? also how do I re-install one at a time ? Sorry to ask dumb questions but everytime I plug a USB in the PC installs everything automatically.Also another weird thing I noticed on the CH yoke which is not being recognized is that some of the buttons are stuck ON when I go into the gaming options in Windows...any ideasmany thanks...JB

Cleaning the system of USB drivers is actually quite tedious, so lets start with something simpler first.If you swap devices (ie. plug the yokes into the other's USB socket on your PC), does the faulty yoke now work? If by swapping the devices results in the faulty yoke working then you may have a defective USB port or indeed, the USB HID drivers need to be flushed out of the system.Does the CH Yoke use its own USB drivers or windows default drivers...i.e. did it come with a driver disk of some kind?Are you using XP? XP recently released a USB device driver fix, so make sure you are up to date with your SPs. M$ does not indicate this IMPORTANT USB driver update as a "critical" update, so you'll need to select it from the update list yourself or it won't be installed! I simply don

Hi leo...thanks for your help on this. I finally found my problem...for some reason MS FS2002 on the PC was the problem and so I uninstalled and then re-installed it and everything was fine...many thanks for your help troubleshooting....JB
