USB keyboard and mouse not detected at boot with kernel 5.13.4, 5.12.11 is OK
by Didier Spaier from LinuxQuestions.org on (#5MK3D)
System: Slint64-14.2.1 based on Slackware64-14.2
kernel generic + initrd (kernel config very close to the one used for Slackware-current)
Symptom: USB keyboard and mouse don't work after booting so no way to log in when using a 5.13.4 kernel, no issue with 5.12.11. Which is sad as 5.12 is tagged EOL upstream.
I have added a few commands at the end of /etc/rc.d/rc.M to investigate:
Code:kerver=$(uname -r)
dmesg >/tmp/dmesg$kerver
lsmod >/tmp/lsmod$kerver
lsusb >/tmp/lsusb$kerver
modinfo usbhid >/tmp/usbhid$kerver
cat /proc/bus/input/devices >/tmp/input_devices$kerverI have compared the output of lsmod after booting in both cases, nearly identical.
"modinfo usbhid" gives the same output with both kernels, kernel version put aside.
In dmesg5.12.11 but not in dmesg5.13.4 I find these lines:Code:input: Lite-On Technology Corp. USB Multimedia Keyboard as /devices/pci0000:00/0000:00:1c.5/0000:06:00.0/usb3/3-1/3-1:1.0/0003:04CA:005A.0001/input/input0
