No. All the USB posts are USB 3. I went out and bough a Microsoft keyboard. That was not recognized either.
I’m pretty sure that the problem is the USB3 controller.
I don’t know if you know this, but for the record Crucial has a similar method for updating their SSD firmware. They have you create a bootable CD using a small Linux system. Their boot CD works on my Mac Mini.
I’m pretty sure that you could make this work. If you send me an email off the forum perhaps I could do some beta testing for you.
For now I’m just going to wait…
