GA-990FXA-UD3 (rev. 4.0 Bios: F2) USB issue

Hardware Hub Motherboards
1

Looking for some help with an issue I ran into. I am working on a PC for a friend of mine. He has an issue were his WiFi adapter (Asus USB-N53) will randomly turn off when under heavy load. The USB port its connects to wont detect any other device until we reboot. He has just been moving the adapter to a different port when it happens and keeps going.

The error message in the event viewer:
"A timeout occurred while waiting for the EHCI host controller Interrupt on Async Advance Doorbell response."

Steps taken:
-Installed latest AMD Chipset drivers (9.0.916.0)
-I found that the USB-N53 uses a RT2870 chip from Mediatek.
Visited the Mediatek website and downloaded newer drives then Asus had available.

PC Build:
Windows 8.1

have you tried plugging it into USB 3.0 port(+ USB 3.0 drivers)? ive had problems 2.0 ports on the same motherboard (rev 3.0).

Go to the gigabyte website and update your usb controllers drivers. I used to run the same board and there were a surprising number of driver updates available.

No, not yet. You bring up a good point though. I forgot to mention that I am using the USB 2.0 that are run by the South Bridge AMD SB950. I guess its an option to move it to the USB 3 ports that are run by separate VIA controllers. I would really like to figure out why this is happening though...

I took a look but they only have updates for the VIA USB 3 controllers. (I went ahead and updated them any way)
Didn't change anything though. There is a newer Bios F3 that i can try. The notes didn't mention anything about fixing USB issues though..

A lot of times a bios update just helps general stability. I'd try it, and if it doesn't work I'm stumped.

7

That is certainly weird.

Does the Windows Event Log have anything to say?

8

if there is a bios update availeble, i would recommend to try that first.
sounds like some kind of a power issue.

9

Have you tried playing with ehci/xhci hand off settings in the bios, those can cause all sort weird issues like hang at post with usb flash drives (happened on a gigabyte z77 board my brother uses). Try turning both of those off or on, etc.

Updated the Bios today. He is going to use it for a while and see if the issue continues.

Well on F3 Bios the USB adapter still crashes but now comes back up on its own without a reboot.
The only issue is that now is that when the PC wakes from sleep the CPU fans doesn't spin up.

I did some googling and others have reported this issue as well but giga-byte hasn't addressed it yet.
I sent them a form letting them know we had the same issue and flashed back to F2.

12

Just an update, Giga-byte emailed me back with Bios F4a to try. Supposedly it should fix the CPU fan issue. I'll have to check it out the next time I get a chance.

I have a 990fxa-ud3 v1.1, got it jan 1 2012, been using it ever since nonstop. Firstly, the USB 2.0 in the amd 950 chipset has a filter driver which is updated when you get the AMD chipset drivers. You should try getting those for the OS that system uses. You should also make sure the northbridge has some sort of active cooling blowing on it. I went with an evga superclock tower heatsink and due to zero "splashdown" cooling from the cpu fan it overheated until I replaced the original cooler with a chipset cooler that was a minitower heatpipe cooler. I wouldnt reccomend the one I got, as I had to modify it to make it fit and then had to thermal epoxy it on, but it solved my problems which were numerous including random usb timeouts with devices.
