I have a late 2013 Retina MacBook Pro and have just installed Windows 8.1 Pro using Bootcamp Assistant. But now when I plug in a USB 3.0 device, the computer will say I am using a USB 2.0 port. It seems there is some problem with the USB 3.0 driver. Please help.
Thanks!
MacBook Pro (Retina, 15-inch, Late 2013), OS X Yosemite (10.10.3)
Please use System requirements to install Windows on your Mac using Boot Camp - Apple Support and Boot Camp: Install or repair Boot Camp drivers or Boot Camp: Solve Windows support software installation problems. BC drivers will provide USB3 support if your Mac has appropriate hardware and supports USB3 on the OS X side.
Am already following the instructions and the flash drive that I use to install Windows is created by BCA. I am using a late 2013 retina MBP and it has USB3.
The flash drive on which the Windows Installer is created should be USB2, because the installer does not contain a USB3 driver. The Mac hardware supports both USB2 and USB3 and will do what is necessary. A USB3 installer flash will give you a black screen or no bootable device. I suggest you find a USB2 flash device. Using a USB2 external HDD is not recommended, because it confuses the Installer on destinations available fork Windows installation.
I use a SanDisk Cruzer USB2 which has 100% success rate on all the Macs I install Windows on.
Windows 8.1 Pro on Bootcamp only can use USB 2.0
