The NV+ has 3 x 2.0 usb ports yet the pci_devices.log states 2 of the ports are 1.1

Hi

 As I stated in subject the pci_devices.log reports 2 of the usb ports as 1.1(see below) but NV+ is supposed to have 3 x 2.0 usb ports 1 front 2 rear.

 

So if that is the case that 2 of the usb ports are 1.1 which of the ports is 2.0, front or back?

Thanks

      Yes I see what you mean 1.1 UHCI controllers are for compatibility.

       

      I will do some more investigating. The logs also give a history of which usb port has what device connect and is using which controller so I will try using each port and see what the logs say.
