 Posted: Sat Mar 11, 2017 1:28 pm Post subject: USB ports don't work |
 |
|
I have a motherboard Gigabyte Z170-D3H with a fresh Gentoo Linux installed (self-compiled kernel 4.9.6-gentoo-r1) and few USB devices connected (Flashdrive, Keyboard and Mouse). But USB ports don't work.
When I type lsblk, there is only my system disk sda.
lspci | grep USB returns:
| Code: | | 00:14.0 USB controller: Intel Corporation Sunrise Point-H USB 3.0 xHCI Controller (rev 31) |
lsusb returns:
| Code: | libusb: debug [libusb_init] created default context
libusb: debug [libusb_init] libusb v1.0.19.10903
libusb: error [op_init] could not find usbfs
unable to initialize libusb: -99 |
dmesg | grep 'USB\|usb' returns:
| Code: | [ 0.293570] ACPI: bus type USB registered
[ 0.293665] usbcore: registered new interface driver usbfs
[ 0.293756] usbcore: registered new interface driver hub
[ 0.293850] usbcore: registered new device driver usb
[ 0.987392] ehci_hcd: USB 2.0 'Enhanced' Host Controller (EHCI) Driver
[ 0.987449] ohci_hcd: USB 1.1 'Open' Host Controller (OHCI) Driver
[ 0.987487] uhci_hcd: USB Universal Host Controller Interface driver
[ 0.987548] usbcore: registered new interface driver usblp
[ 0.987592] usbcore: registered new interface driver usb-storage
[ 0.992362] usbcore: registered new interface driver usbhid
[ 0.992376] usbhid: USB HID core driver
|
And usb-devices returns nothing. |

BlueManCZ ...
I don't see XHCI in dmesg so it's probably not enabled, what does the following show:
| Code: | | % if [[ -f /proc/config.gz ]]; then zgrep XHCI /proc/config.gz || grep XHCI /usr/src/linux-$(uname -r)/.config ; fi |

Thanks for reply khayyam.
It doesn't show anything, because file /proc/config.gz doesn't exist.
EDIT #1
This command:
| Code: | | grep XHCI /usr/src/linux-$(uname -r)/.config |
shows:
| Code: | CONFIG_USB_XHCI_HCD=y
CONFIG_USB_XHCI_PCI=y
CONFIG_USB_XHCI_PLATFORM=y |

BlueManCZ ... yes, I should have used an 'else' rather than an '||' (or)
| Code: | | # if [[ -f /proc/config.gz ]]; then zgrep XHCI /proc/config.gz ; else grep XHCI /usr/src/linux-$(uname -r)/.config ; fi |

CONFIG_USB_XHCI_PCI=y

OK, it doesn't show in the above dmesg, which I would expect it would, try greping explictly for xhci
| Code: | | # dmesg | grep -i xhci |

dmesg | grep -i xhci shows nothing.
I exported entire dmesg log to .txt file so you can use search engine in your browser.
Here is it: dmesg_log.txt |

| If you can load the xhci modules manually after booting (via the modprobe command), perhaps you just need to add them into your /etc/conf.d/modules file. |

I note the date of the kernel in the dmesg output is 2nd Mar, but this thread started 11 Mar. So perhaps a kernel updated for XHCI didn't get copied to /boot?

When I try to load module manually with modprobe xhci_pci, it returns:
| Code: | | modprobe: ERROR: could not insert 'xhci_pci': Exec format error |

That's a good point! But why is there old date? Today I compiled new kernel according to this manual, ls -al /boot shows:
| Code: | -rw-r--r-- 1 root root 147803 Mar 13 17:27 config-4.9.6-gentoo-r1
drwxr-xr-x 2 root root 1024 Mar 13 17:27 grub
drwx------ 2 root root 12288 Mar 2 11:09 lost+found
-rw-r--r-- 1 root root 3211001 Mar 13 17:27 System.map-4.9.6-gentoo-r1
-rw-r--r-- 1 root root 5303088 Mar 13 17:27 vmlinuz-4.9.6-gentoo-r1 |
But first lines in dmesg are:
| Code: | [ 0.000000] Linux version 4.9.6-gentoo-r1 (root@livecd) (gcc version 4.9.4 (Gentoo 4.9.4 p1.0, pie-0.6.4) ) #1 SMP Thu Mar 2 12:43:04 -00 2017
[ 0.000000] Command line: BOOT_IMAGE=/boot/vmlinuz-4.9.6-gentoo-r1 root=/dev/sda4 ro |
But ls -al /var/log/dmesg returns:
| Code: | | -rw-r----- 1 root root 51587 Mar 13 17:28 /var/log/dmesg |

BlueManCZ,
You forgot to mount the /boot partition before you installed the kernel. It wan installed to the /boot directory on the root partition.
Grub won't find it there.
When /boot is not mounted, ls /boot should return nothing.
With /boot mounted, your kernels and /boot/grub will be there.
