 |
|
Hello,
I'm having trouble getting the usb ports on my laptop to work. lspci shows:
| Code: |
00:14.0 USB controller: Intel Corporation 100 Series/C230 Series Chipset Family USB 3.0 xHCI Controller (rev 31)
04:00.0 USB controller: ASMedia Technology Inc. ASM1142 USB 3.1 Host Controller
|
If i boot manjaro, lspci -k shows that the xhci_hcd module is being used for both. I built the xhci module into my gentoo kernel (currently gentoo-sources-5.11.14). If I boot gentoo and lspci -k, it shows no module for that hardware. dmesg | grep xhci returns nothing.
Does anyone have any suggestions on where to look next?
Thanks!

Not really, but check the kernel version:
| Code: | | file /path/to/your/installed/kernel_image |

Yes, your booted kernel is the same as you think it should be.

Only in your kernel config !
I think you made the kernel config by yourself and you did a stub kernel. The only question is:
Did you made all configurations with "make menuconfig" or did you some configurations by editing the .config ?
You know, when you activate some parameters in the kernel config, this can lead to (invisible) activating of other parameters ? |

You didn't miss CONFIG_USB_PCI ... did you?
