Considering there is a page fault, did you already experiment with iommu=pt?

Hi Mario, it did not cross my mind it could be AMD IOMMU related, adding
iommu=pt to kernel boot line did in fact make things better! My USB keyboard
and mouse are now surviving.

I don't think that proves it to be an AMD IOMMU bug. It could be an ACPI IVRS
table (BIOS) issue or a driver bug.
Can we see the whole dmesg with iommu=pt? Besides keyboard and mouse, what
happens to the other USB device now?

At the moment I'm on my other system with B550 chipset and Ryzen 5800X and have
2TB SanDisk Extreme 55AE plugged into that, however this system was also
exhibiting same exact problem as original (B450 motherboard with Ryzen 5600X),
so I can give you a dmesg from current B550 system (see attachment), and yes
other USB devices or working fine now (I have an USB SD card reader plugged in
and Oculus CV1 and they're working fine)

So you can see in there the IO_PAGE_FAULT and decode it using
https://www.amd.com/system/files/TechDocs/48882_3.07_PUB.pdf p149/p150.
The domain ID 0x18 is selected by the driver, I don't believe it's meaningful
in this case. It seems to me that the device/driver for the device is causing
the XHCI controller to try to write to address 0xffcf0000.
