Creating a bug report/issue

I have searched the existing open and closed issues

Required Information

  • DietPi version | 10.5.2
  • Distro version | trixie
  • Kernel version | Linux odroid2 6.18.34-current-meson64 #1 SMP PREEMPT Mon Jun 1 15:51:08 UTC 2026 aarch64 GNU/Linux
  • architecture | arm64
  • SBC model | Odroid C4 (aarch64)
  • Power supply used | 12V 2A vendor power supply
  • SD card used | eMMC 16GB

Additional Information (if applicable)

N/A

Steps to reproduce

I burned the DietPi_OdroidC4-ARMv8-Trixie.img.xz to a 16GB eMMC that worked fine with the hardkernel supplied image. I then boot with the following hardware connected:

  • HDMI monitor
  • usb keyboard and mouse (via usb hub, but it fails when attached to the on-board USB ports as well)
  • hardwired ethernet
  • wifi dongle (Edimax Technology Co., Ltd EW-7811Un 802.11n Wireless Adapter [Realtek RTL8188CUS])

I see the getty message on tty1 on the console screen, but the keyboard does not work. This happens with the usb keyboard on hub or direct connect on the odroid.
When I ssh into the system via hardwired ethernet, I run lsusb which shows the keyboard. I can unplug/replug and see the keyboard/sub change in dmesg output.

Using dietpi-config, I added xfce and started the greeter and enabled autologin. Then rebooted.
I get the graphical desktop and the mouse works fine on the hub. Still no keyboard.
When I boot with a hardkernel image, the keyboard works fine. I have this keyboard issue with armbian images as well.

  1. …

Expected behaviour

I should be able to log in using the USB keyboard.

  • …

Actual behaviour

Keyboard does not result in keystrokes sent to tty1.

When you connect it, do you get messages from dmesg, that it was recognized by the system?
You can also share the output of lsusb

What do you mean by “get messages from dmesg”? I don’t think I saw anything on the tty1 monitor. If I run dmesg after plugging in the usb hub, I see:

This is what I meant by “I can unplug/replug and see the keyboard/sub change in dmesg output.” in my original message. (sub should have been usb)

(A) lsusb output (using the usb hub for mouse and keyboard) is:

I use the hub because I am swapping the mouse/keyboard between 2 different computers.

Also I think I did a hub unplug between (A) and (B). That explains the shift in usb mouse from device number 008 to 010.

In this case it might be related to kernel and/or overlays. Means we would need support for @MichaIng

5

I was able to boot and use: ubuntu-24.04-6.6-mate-odroid-c4-hc4-20260512.img.xz from ODROID Images without issue. So at least one 6.x kernel works with this keyboard.

I have to admit I am not sure what an overlay does. If the kernel sees the device as a USB keyboard it should just work right. Don’t all USB keyboard speak the same protocol?

Interesting, since USB input devices do not require any specific drivers or device tree entries, and generally the device is detected.

  • Do you have another USB keyboard to test whether it affects only this particular one?
  • Does the same happen on all 4 USB ports?
  • Does the USB hub have a dedicated PSU?

At least on my Odroid N2+, which shares the same kernel, my Logitech wireless keyboard with their nano USB dongle works on all 4 USB ports.

Hello:

Interesting, since USB input devices do not require any specific drivers or device tree entries, and generally the device is detected.

That matches my expectations.

  • Do you have another USB keyboard to test whether it affects only this particular one?

I do, but it is another asus keyboard and exhibit the same issue. I’ll have to see if I can find a usb keyboard from another manufacturer for testing.

  • Does the same happen on all 4 USB ports?

I’ve tested 3 of the ports and plugging the keyboard into any of them recognized the keyboard, but no keystrokes are passed. I am typing into
a terminal window and get no output. I can disable the graphical autologin and return to text only getty on tty1 if that would help.

I don’t know if I have virtual terminals available on the hdmi output. It looks like tty1 is the only one available and I didn’t see a getty for other virtual terminals. Note I have disabled the serial/uart ttySX and ttyASM0 gettys.

  • Does the USB hub have a dedicated PSU?

It does not but the mouse works fine through it. Also I have tested
by plugging the keyboard into the USB ports on the SBC. So even without a hub, the keybord is recognized but doesn’t sent characters/keycodes.

Other ideas?

Ok found a different keyboard. Plugged it into the same port as the non-working keyboard and it works as expected. This is the dmesg/lsusb output for the new working keyboard:

Anything useful here?

Compared to the other output, this keyboard is explicitly detected as input device, loading the hid-generic driver. The same is the case for the mouse, but not for the ASUS keyboard.

See how it is detected differently as well:

[12335.324749] usb 1-1.2.4: Product: Asus Keyboard

vs

[  232.795037] usb 1-1.4: Product: HID Keyboard Device

One through the hub and one directly? Anyway, the functional keyboard is detected as generic HID keyboard device, hence the driver jumps in. The other is detected as “Asus Keyboard”, which is probably not recognized as keyboard device to pull in the generic (or any available) driver by mainline Linux.

Would be interesting whether this keyboard works on a x86_64 system with DietPi or Debian.

If it works with the Hardkernel Debian image, it would be good to check which kernel modules are loaded an available, when the ASUS keyboard is attached:

lsmod
grep -E 'CONFIG_(INPUT|KEYBOARD|HID)' /boot/config-*

E.g. CONFIG_HID_ASUS is not enabled in our case, though this seems to be for a small set of embedded notebook keyboards and touchpads: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/tree/drivers/hid/Kconfig#n187

I have a bootable stick with LMDE - linux mint debian edition 7 on it.
Hopefully that will work. If you need me to find a live debian and boot from it I can give that a shot as well.

The keyboard works fine (via the usb hub) with LMDE it.

TL;DR CONFIG_HID_ASUS is set to m or y on working systems

With the lmde x86 box, lsmod and your grep command
produce this (voluminous) output:

I can’t use the stock hardkernel image with a 4.x (9??) kernel because
I want to run k3s on it and need cgroups v2 with the cpu component.
The stock 4.9 kernel won’t do cgroups 2 including the cpu component AFAICT.

All my attempts to upgrade the hardkernel image’s kernel to 6.x by manipulating /media/boot lead to a non-booting image.
Hence a replacement image with a working kernel.

I was hoping to use dietpi as it is smaller, has a modern kernel and provides some TUI config tools similar to what I find on my rasp pi.

Thanks, with CONFIG_HID_ASUS=m and the hid_asus loaded I think it is clear. I’ll patch our config and trigger a build. Hang on …

EDIT:

12

Looks like the job failed in Build Asset.

13

Yeah I fully implemented a new overlay auto-builder the last days, and did not test it for all kernel families yet. Might happen a few more times, since the overlays are now also all tested against one or more base device trees. Might reveal a few buggy ones.

14

The build is ready:

G_DEV_TEST_FIRMWARE
15

Looks good. I assume this will be included in all future release versions?

Also you mentioned:

What are overlays? New/updated kernel modules not included in the upstream build?

Again thanks for the fast turnaround. Now to do the work I actually have to do.

Right. If it works, I’ll assure this module is added to all our kernel builds.

Device tree overlays allow to enable/disable/configure onboard features of SBCs. In most cases this is about GPIO features, like UART, I2C, SPI, 1-wire, PWM interfaces etc. But also, e.g. on the Odroid N2, there is an overlay to enable access to the SPI flash storage, to flash/update the bootloader for booting from USB (and potentially SATA and NVMe). Since it shares the same bus with the eMMC module, the latter needs to have its bus width = max bandwidth reduced. For this reason it is not enabled by default, but behind an overlay. Luckily, for the Odroid HC4 with its SATA ports, this is not the case/needed.

@rouilj
Just to be sure: that kernel build really made the ASUS functional?

18

Correct. The keyboard worked after running G_DEV_TEST_FIRMWARE and a reboot.

To confirm I just:

  1. reburned the original DietPi_OdroidC4-ARMv8-Trixie.img.xz to my eMMC
  2. verified the keyboard didn’t work on tty1
  3. logged in as root via ssh
  4. ran through setup (disabling the uart)
  5. ran G_DEV_TEST_FIRMWARE
  6. rebooted
  7. verified the keyboard works on tty1

So everything looks like it works.

Thanks.

Good, the driver will be available in any of our kernel builds from now on: config: enable ASUS keyboard driver · MichaIng/build@2a2062d · GitHub
