USB Devices Stop During Install

[enxio27]

Fresh install of Win7 Pro on new hardware from a USB DVD. As soon as all of the files are loaded and the first screen appears (asking for country, etc.), all of the USB devices (DVD drive, keyboard, mouse) shut off. Tried a different mouse, same result. I'm suspecting that it might be a driver issue, but is there anything else I should look at, also?

If there is a setting in the bios for legacy usb turn that on. If the usb is usb 3 there are no drivers in win7 install that could be your problem How do I get usb 3.0 drivers onto my windows 7 system? - Microsoft Community

Are your mouse and keyboard wireless? If so, you might have to try to connect to the receiver at the point you're at.

No, both are wired.

Already had the bios set to legacy. I thought I had already slipstreamed the USB 3 drivers into the ISO a while back, but evidently I've lost that version of the ISO somehow and I'll have to do it again.

I was thinking about this yesterday and my answer was a little bogus because you said the optical drive also wasn't connected. Sorry about that.
