Trouble installing Windows 7 via bootcamp in OS 10.10.3

I just bought a 27" I Mac Retina with a 4 gig I 7, 256 gb flash, 8 gb Ram (soon to be upgraded) and 4 gig video Ram running OS 10.10.3. I downloaded the latest Apple support software onto a flash drive, and used a Windows 7 64bit install disc that I've used successfully on my 09 Mac Pro running OS 10.9.5. Partitioning and installing/expanding the Windows software goes without a hitch. After restart, when it asks for a computer name, the keyboard and trackball won't work. Because I can't input any info, I can't proceed with the install. I'm using a wired keyboard and trackball so bluetooth isn't the issue. Any ideas would be greatly appreciated.

The flash drive must be a USB2 device, a USB3 device will not work, because Windows has no USB3 installers that are installed. USB3 drivers get installed when you install the BC drivers package.

Here is how you can check.
