Question

Gigabyte GA-78LMT-USB3 usb 3.0 not working still sends power

by Bur5t / November 12, 2015 5:35 PM PST

I've been having issues with my motherboard in the past few weeks where the only possible way to use my computer is through the various USB 2.0 ports in the back of my computer. The front two and back four USB 3.0 ports have simply stopped being recognized by Windows 10. I have checked device manager, and none of the usb root hubs have an alert (triangle with an exclamation point) overlaying the icon. Angry The computer is still barely functional with a 4 port USB hub in it, but I don't want to depend on USB 2.0 anymore. Please help! I do have a program called Lightshot, so I can send screenshots if you like. Here are a few that I took just to help you figure out my problem.

P.S. Do you think a driver that I may have installed (Which I removed, it was a PS3 controller driver) could have affected it?

Start at the beginning then

First reinstall the AMD southbridge and northbridge drivers, and THEN try to install the VIA USB3 driver files. Obviously the USB3 is a tacked on chip instead of it being available in the southbridge as one would expect based on past method. Of course if you are running generic windows drivers for the bridge chips, then it won't be able to see the VIA added USB3 controller chip, probably an adjunct to the AMD controller south bridge.

It will either install or not
by James Denison / November 12, 2015 9:23 PM PST

If it won't install, then try to install using a compatibility mode for earlier 64 bit OS. It won't do anything worse than you already experience.

one guy said
'Turn off PC, Turn off, Cut off power to the PSU, Wait about 10 seconds, Turn on.'

would that work

doubt it, but won't hurt
by James Denison / November 13, 2015 11:58 AM PST

Also might try shorting the CMOS, the shorting jumper is near the coin battery. It resets the motherboard to defaults. Maybe there's just something wrong with the mobo. It's also possible you don't have revision 6 of this motherboard, but earlier one.

It's all fixed! (Also some other smaller issues too)
by Bur5t / November 13, 2015 12:17 PM PST

I first shorted the CMOS. That did nothing. (Made the startup a tiny bit faster, had to change default hdd for startup) Then I turned off the computer, turned off the PSU, and back on, turned on the computer. The issue apparently was that the USB controller didn't turn off for a long enough time. I was confused when it worked again, too. But I'm happy that it works! Thanks for all the help Happy

The problem is, the Via Hyperion Pro USB drivers are not working for Windows 10 either, so the Etron drivers do not work as well. I have the rev. 6.0 of the motherboard.

The executable in that 2nd link worked perfect!
I first tried to have device manager search the extracted folder for the driver, but its an actual executable you have to run in order to install the driver. SO once I realized that, it worked perfect!

I have Rev 6.0 on windows 7 home premium 64bit.

Via Chipset drivers fix this issue
by sk1965 / March 27, 2016 4:12 PM PDT

I had the same issue. Looking at the GA-78LMT-USB3 manual, I found a block diagram that shows the 4USB3 ports are managed by a VIA VL805. On the CD I found multiple USB3 folders in the "Chipset" directory. The Gigabyte website only has the Etron drivers. These did not work for me. So I went down the list installing every dam USB3 driver on the disk. Still no result. I finally deleted the USB controller from "Device Manager" and rebooted. To my pleasant surprise. the controller was detected as a VIA device and the problem was solved.

@sk1965 What did your device manager list look like after you got everything to work.
I no longer have any errors but i still have a ? next to xHCI Root Hub 0 under other devices.

My USB3.0 still doesnt work.
