IMac 27" MID 2015 can't install windows 7 (Keyboard and Mouse not working during installation due to USB3.0 not readable) HELP!

I've searched for this error for days, it turns out that the Windows 7 is not support USB 3.0 on installation and that is the reason I'm stuck and can't install the software.
I've checked that all my ports on my IMAC are USB 3.0 will there be anyway that I can use my external mouse & keyboard will work?
I also have the Magic Mouse and Wireless keyboard, but once I'm in the installation it does not work as well

Any help will be greatly appreciated, I'm getting frustrated....

iMac with Retina 5K display, OS X Yosemite (10.10.2)

2015 Macs do not support W7 officially. You can use USB2 flash drive to build an installer, but 2015 Macs do not need a USB. Please see https://help.apple.com/bootcamp/assistant/6.0/#/bcmp173b3bf2 for reference.

Thank for your quick reply, My bootcamp has an error whenever I try to download or install the windows 7 using Boot Camp Assistant which lead me to manually installing Windows 7.

Now I'm stuck at the "Language" option on the Windows 7 Installer, can't choose or continue because my mouse nor my keyboard can't be recognised.

Will there be a way for me to set the Windows 7 installer to read USB 3.0?

I have not tested this myself, but you can try - http://codeabitwiser.com/2014/03/how-to-install-windows-7-with-only-usb-3-0-port s/ .

Is your USB flash drive a USB3? The Windows Installer does not have drivers to read USB3 (but the link above may help get the USB3 drivers).

If you can find a USB2 flash disk, it would make it much easier.

I'm pretty sure that this I'm using a USB2 flash disk, but when I try to use BCA the error "Boot Camp only supports Windows 7 or later installation on this platform. Please use an ISO file for Windows 7 or later installation."

I've tried using the procedure on updating the info.plist but I ended up on crashing my BCA and I can't get Xcode to try the fix on the BCA crash. any thoughts?

Would you happen to know if Windows 8/8.1 or 10 would have a USB3.0 drive on the installer?

Please verify that you are using a USB2 flash drive.

Your physical USB ports will support both USB2 and USB3 flash drives. A 2015 model officially does not support W7 as noted in Install Windows 7 and earlier on your Mac using Boot Camp - Apple Support . Modifying the .plist is not a good idea.

You can try a SMC and NVRAM reset with all external storage disconnected.

Resetting the System Management Controller (SMC) on your Mac - Apple Support

and try BC Assistant with W7.

On your current USB, can you check Bootcamp.xml and the line which has Product Version? What version of drivers do you have?

Yes, it is a version 2.
I have managed to get a hold a of Windows 8.1 iso, during halfway of the BCA installation my flash drive gets ejected and I ended up in a dead end.

Is this during Windows installation, or during BC drivers installation after Windows is installed?
