It's the 32 bit Vista. I know that the USb ports work on my pc due to using our digital camera on them and we have no problem. When I plug the Xbox 360 Vision Camera into a USB port on my pc the device manager runs and does all of the driver stuff and clears everything listed but when I go to Windows Update it says that there is a Peripheral update specifically for the Xbox 360 camera. This is the update thats popping up the error code. Right now I am unable to use the vision camera and I'm thinking I won't be able to until I get this update on my pc.
