 |
|
Hi.
After I upgraded my kernel from gentoo-sources-6.1.57 to 6.6.13, external USB devices stopped being recognized by the kernel. When I plug in an USB flash drive while watching the syslog (on ttty 12), just nothing happens: no message from the kernel shows up as usual that a new SuperSpeed device has been plugged in. With the old kernel, there is never a problem. It affects only external usb devices, being them storage devices or printers.
I experimented with the kernel config (building USB features in or as modules) but the change somehow has only a shorttime effect. After booting into the new kernel it works, but stops again after a while. In the moment I have the following difference in the 6.6.13-config compared to the working 6.1.57-configuration:
| Quote: | # diff .config ../config-6.1.57 |grep USB
< CONFIG_BT_HCIBTUSB_POLL_SYNC=y
< CONFIG_USB_MON=y
> CONFIG_USB_MON=m
< CONFIG_USB_STORAGE_USBAT=m
> # CONFIG_USB_STORAGE_USBAT is not set
< CONFIG_USB_STORAGE_JUMPSHOT=m
< CONFIG_USB_STORAGE_ALAUDA=m
> # CONFIG_USB_STORAGE_JUMPSHOT is not set
> # CONFIG_USB_STORAGE_ALAUDA is not set
< CONFIG_USB_STORAGE_ENE_UB6250=m
> # CONFIG_USB_STORAGE_ENE_UB6250 is not set
< CONFIG_USB_UAS=m
> # CONFIG_USB_UAS is not set
< CONFIG_USB_ROLE_SWITCH=m
< CONFIG_USB_ROLES_INTEL_XHCI=m
> CONFIG_USB_ROLE_SWITCH=y
> # CONFIG_USB_ROLES_INTEL_XHCI is not set

Like before, with the old kernel, I have USB, USB_SUPPORT, USB_COMMON, USB_HID built into the kernel, but USB_STORAGE, USB_XHCI, EHCI, UHCI and OHCI as well as the corresponding _PCI and _HCD built as modules.
Weird no. 1: Often, when I plug in a flash drive, instead of the USB notifications a message appears from the driver of the LAN card:
| Quote: | | kernel: e1000e 0000:00:1f.6 enp0s31f6: Failed to disable ULP |
Weird no.2: In one case, the kernel even thought that a LAN cable had been connected: it printed that the LAN link had come up and the interface activated - although I did not plug in a cable.
I'm not sure if this gives a hint, but at least once after reboot I managed to make the device known to the system. After the weird three first lines in the syslog (the power cycle and the enumeration problem) I plugged the USB stick in again and suddenly it was there:

But after umounting and unplugging it went back to the broken state again: how often I plug it in, it triggers no reaction by the system.
What else can I do? I'm a bit out of ideas...
Just stick to 6.1.57 and wait for the next stable kernel?
The machine is a 4 years old Fujitsu Ultrabook running Gentoo from the beginning, with initramfs, lvm and encrypted root. All my other systems seeing the same kernel update had no problem at all.
