I noticed when I upgraded from debian's 4.19.0-18 (working) to 5.10.0-10 (broken). I git bisect'ed until I found that this patch is the culprit. Upstream 5.17.0-rc2 is still broken, but 5.17.0-rc2 with this patch reverted works. > > > > lsusb when things work : > > > > https://paste.debian.net/hidden/2a964425/ > > > > lsusb when things are broken : > > > > https://paste.debian.net/hidden/0376920c/ > > > > dmesg when things are broken : > > > > https://paste.debian.net/hidden/780ca112/ > > This dmesg says: > > [ 1.049161] PCI: Using host bridge windows from ACPI; if necessary, use "pci=nocrs" and report a bug > > have you tried that?

Sorry, my email wasn't very clear, I gave the dmesg for two very different kernel versions. But anyway, it doesn't really matter since Andriy Shevchenko found the problem.
