help to fix usb bug in kernel 6.2/6.1 for udoo quad

[gioelebianchi00]

Hi.

 

i've compiled udoo quad image using armbian build framework. The kernel is 6.x.x.

When i boot the image on sdcard, usb ports don't start: the mouse's led don't turn on and keyboard too.

What can i do to solve this problem?  what paramaters do i have to enable?

 

thanks

I come back here every few years to rebuild my UDOO home brew controller.. 

 

Seems like USB was disabled around kernel 5.19 (https://github.com/torvalds/linux/commit/8f2ca252ee1f848d3eec9ebbbf3c3881cb423322).  Got in touch with Fabio and he gave a super fast response and put two patches in to review.

I'm building it now - might get around to testing tonight, but will probably be a week or so.

Thank you so much

Okay - finally got around to testing (with more back and forth between Fabio).  There were some updates to what he patched getting it working with kernel 6.9 (ONBOARD_USB_HUB to ONBOAD_USB_DEV), however since armbian is on 6.6/6.7, this patch was needed as well: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/drivers/usb/misc/onboard_usb_hub.c?h=v6.9-rc3&id=65e62b8a955adebee8634804d8f72599213c2774.

 

Attached is the patch I used to build & run successfully w/ wifi & usb enabled (for current - i haven't tested edge).  Make sure you do a kernel config and set ONBOARD_USB_HUB to y - seems like config/kernel/linux-imx6-current.config is significantly different than cache/sources/linux-kernel-worktree/6.6__imx6__armhf/arch/arm/configs/imx_v6_v7_defconfig (attached patch only modifies the kernel work tree)

@chiefwigms please submit a PR for this to get included into Armbian

[SteeMan]

@chiefwigms As this board is in status community maintained, no Armbian resources are assigned to work on or support this board.  Support/maintenance comes from the community.  That means people like you submitting PRs to maintain/improve functionality.  Without active community participation the board will langish and eventually be moved to end of support/end of life status.

@chiefwigms Is there a chance that these fixes will someday be included in the mainline kernel?

[chiefwigms]

These two patches:
https://lore.kernel.org/linux-arm-kernel/20240401023347.3114484-1-festevam@gmail.com/

https://lore.kernel.org/linux-arm-kernel/20240401023347.3114484-2-festevam@gmail.com/

Should get in the 6.9 kernel - as well as changing ONBOARD_USB_HUB to ONBOAD_USB_DEV in the kernel config

https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/drivers/usb/misc/onboard_usb_hub.c?h=v6.9-rc3&id=65e62b8a955adebee8634804d8f72599213c2774 is already in mainline but was committed after 6.6/6.7.

 

I'll make a PR sometime this weekend and try to test with edge, as well as an updated defconfig - don't really have much time these days to do anything 🥲

Help me to understand. Have patches already been into armbian kernel? So I only need to compile armbian kernel right?

[chiefwigms]

you'd need to add a user patch at the moment.. finally had time to make a PR

Thanks. Now it works fine

 

Thank you
