Eric.C Posted January 8, 2008 Share Posted January 8, 2008 What's the difference? I've noticed that some USB ports on my computer are not working properly, I checked them in system profiler and the only difference other than the bun number is the host controller driver. The working ones have AppleUSBECHI as the drive, and the non working ones have AppleUSBUCHI as the driver. How do I change it so that I can get all my ports to work?

Headrush69 Posted January 11, 2008 Share Posted January 11, 2008 Can you post a picture of the USB section from System Profiler. Usually the EHCI driver will be loaded if a USB2 device is attached to the port.
