problem usb mass storage and custom kernel

doudootiana · 05-02-2021, 04:09 PM

Hy Everybody

For a Week, i try to configure my custom kernel, to allow the usb mass storage.

I am a newbie and i like to learn, looking for informations and by practicing.
but even if i have found some informations with my friend google

, i don't manage to find where is my error.

Here a part of my dmesg, select the line with the word usb ou storage :

Code:

 dmesg | grep 'USB'
[    4.262180] ehci_hcd: USB 2.0 'Enhanced' Host Controller (EHCI) Driver
[    4.268827] ohci_hcd: USB 1.1 'Open' Host Controller (OHCI) Driver
# dmesg | grep 'usb'
[    3.434106] usbcore: registered new interface driver usbfs
[    3.439816] usbcore: registered new interface driver hub
[    3.445303] usbcore: registered new device driver usb
[    4.275393] usbcore: registered new interface driver usb-storage
# dmesg | grep 'controller''
> ^C
# dmesg | grep 'controller'
[    5.733047] mmc0: SDHCI controller on d00d0000.sdhci [d00d0000.sdhci] using ADMA
[    5.780795] mmc1: SDHCI controller on d00d8000.sdhci [d00d8000.sdhci] using ADMA
# dmesg | grep 'mass'
# dmesg | grep 'storage'
[    4.275393] usbcore: registered new interface driver usb-storage

When i do the line command lsusb, nothing appears.
and no driver usb found in /lib/modules/5.9.0/kernel/drivers

More informations about my project :

My support is a Turris Mox.

I shape my kernel from the kernel net-next 5.9.

I use Buildroot to build a custom Linux,
and i have included exfat fuse and exfat-utils.

thank by advance

Use some pastebin utility (wgetpaste, pastebinit) to paste your kernel .config and give us the link. You may miss CONFIG_USB_PCI in your kernel, just guessing.

hy,
thank you to answer me.

Here, my .config

Emerson · 05-03-2021, 04:52 AM

Code:

# CONFIG_USB_PCI is not set

My guess was correct, fix it.

Hy,
thank again to answer me

i have tried, but same problem.

I even tried to completely recompile

After you reconfigure your kernel you must recompile and reinstall. And then reboot to start using it.

doudootiana · 05-03-2021, 08:53 AM

Hy again

.
I have reconfigure, recompile and reinstall the New Kernel.
I have also restarted from zero and copy the
.conf with your advice.
Can it come from the controller?

Verify your running kernel is the one you built and installed. 'uname -a' Is the build date and time what expected?

doudootiana · 05-03-2021, 09:33 AM

Hy,
i just verify and it's the good kernel.

Here the new .config

and here, the dmesg

Only now I noticed this is not on PC platform, it is some sort of single-board ARM computer. These usually need many options for GPIO and pinctrl enabled, can't help much with these. This is for you to experiment and learn.

Edit: And if you ever start a support thread again please let everybody know what hardware you have. Otherwise it is automatically presumed you have amd64, this is the most common platform.
