I have installed Windows 8.1 through bootcamp. I have to plug in a device that implements the USB 2.0 interface, however, my MBP does not have any USB 2.0 ports, only 3.0.
I know that theoretically USB 3.0 is backwards compatible, but not really. My device is not recognized at all if I plug it in a USB 3.0 port.
I need a way to force the USB 3.0 ports on my MBP to work as USB 2.0. I tried to install different drivers for xHCI with no success. I also tried with an USB 2.0 extension cord with no luck. Some other laptops can change the USB 3.0 ports speed from BIOS, but again, my MBP does not have a BIOS.
What can I do?
