ROG Maximus XII Formula, USB 3.0 issues.

Support

Refreshed my rig with a Maximus XII Formula, 10850k, and all the other goodies to go along with it.

​

Wanted to hook my ElGato capture cards up and I'm getting USB related errors with the machine. Turns out nothing is connecting at USB 3.0 speeds, devices capable of 3.0 give me the error saying it could be faster with a 3.0 port. The HD60S requires 3.0 so it wont work at all, my 1080p ElGato GameCapture shows an error saying unavailable driver (though driver is installed). Some searching says this is related to a USB error. So made sure the bios is the latest version (the one with cryo support), installed all the drivers from Asus, same errors. There are USB 2.0 headers on the mainboard, so I installed a hub and tied all non 3.0 devices into the dedicated 2.0 ports, same thing. Even got the usb c adapter I use on my mac and tested with the 3.1 usb c port. Same issue.

​

I had a 512 nvme laying around, so I installed that and did a fresh install of Windows 10 to the new nvme. Installed Asus drivers, software etc, exact same issues.

Went into the BIOS and played around with disabling legacy usb, xchi handoff, etc. Nothing helped.

I have a Rampage V Extreme X99 board I tested both capture cards on, they work fine. They also worked fine on my old trust worthy Maximus VII Extreme Hero that this refresh replaced.

​

So at a loss, I know sometimes older 2.0 devices don't play well on 3.0 ports, but even using the dedicated 2.0 ports. I still get usb issues and 3.0 just seems to be broken on this. Any ideas would be amazing. Thank you.

My thoughts would be to disable all and any energy save features in BIOS and OS for USB.

Also check that BIOS always provides power to the USB ports (but I guess you already did that)

Hope you find the problem!

I don't think I mess too much with power saving in the bios. I'll check that, thank you.
