Asus Aura and OpenRGB not working

English Hardware
21

Follow-up: Just ran GPUTest from 3DGeeks, it’s from 2014 but still works.
GPU temperature went from ~40C to 65C and fan speed increased ~30% (from 23 to 54%)

22

Correction: apparently there is no i2c_nvidia_smi module. nvidia-smi is a command line monitoring tool.

Browsing https://bugzilla.kernel.org/show_bug.cgi?id=206653 it seems that i2c_nvidia_gpu is for cards with USB type C controllers, which apparently all cards from 2019 on have, even if the a physical port is not present.

Coincidentally or not, the problem with the second monitor (HDMI) getting no signal that I mentioned above is one consequence. Also, my USB2 mouse and kbd do not work at the grub screen. I either wait for the timeout or remove and reconnect the dongles. Weird, and might not be related to this thread issue.

Hi
No USB 2.0 for keyboard and mouse? Is legacy USB support enabled in BIOS?

24

That’s puzzling.

  1. Legacy USB is set to Auto, worked OK until now.
  2. There is a dongle for the mouse and another for the keyboard, both logitech, both connected to the monitor hub, which was connected to a USB 3.1 Gen 2 port at the mobo back panel with an USB 3 A-B cable. The monitor hub has two USB 2.0 and two USB 3.0 (one is fast charging) ports. Both dongles are connected to the hub’s USB 2 ports.
    There are also two USB 3.1 Gen 1 ports available in the back panel, but no USB 2.0.

Now the puzzling thing:
I moved the hub cable to a 3.1 Gen 1 port, and both mouse (in UEFI BIOS) and keyboard (in UEFI and GRUB) are working - for now. Before changing the port to 3.1 Gen 1, I moved the kbd dongle to an USB 2 port in the case front panel (connected to a USB 2 header in the mobo) and the keyboard worked in UEFI/BIOS, as well as the mouse still connected to the hub.

I think there may be a stability problem with the USB cabling or settings, but can’t see it.

FWIW, the mobo manual states:

Due to AMD AM4 series chipset design, all USB devices connected to USB 2.0 port and USB 3.1 Gen 2 / Gen 1 ports are controlled by controller xHCl.

Well, it is working for now. If it starts misbehaving I’ll try with Legacy USB enabled.

Thanks,

Bruno.

Hi
When connected run lsusb -t to see the connection speed and driver in use… AFAIK they should be 12M.

26

For AM4 update BIOS - they had troubles with USB and powerstate.

With AM4 you may get 3 different USB types:

  1. Connected to CPU.
  2. Connected to south bridge. You may experience troubles with it in UEFI.
  3. Additional USB controller on mobo. In that case devices may now work in BIOS/UEFI/boot mode.

Nice tip, malcolm, thanks. With verbose option it also shows the connected devices:

Anyway, it seems to be working OK now, after rearranging some USB cables.

If the problem happens again I’ll open a new thread.

Thanks for the info, Svyatko. I’ll keep it in mind.
