USB keyboards not recognized after major upgrade [solved]

Greetings,

I have updated the system to the latest version and I cannot login again, since my USB keyboards are not working (I tried with two different).

At least I have another computer with ssh to connect to it, and I did many tests:

- acpi=off (grub)
- pci=noacpi (grub)
- downgrading libinput and xf86-input…
- downgrading the kernel version (5.9 and 5.12 or so)
- switching to a kernel 4.19
- disabling acpid.service
- disabling sddm and directly using the virtual console

The keyboards do not work in any place (neither sddm login nor the virtual console). Both keyboards work in another linux machine, they are recognized and listed in lsusb.

Using dmesg:

[ 1609.600354] usb 9-4: new low-speed USB device number 14 using ohci-pci

Any idea what is going on?

Re: USB keyboards not recognized after major upgrade [solved]

Solved by doing `iommu=soft` in grub.
