https://bugzilla.kernel.org/show_bug.cgi?id=213081 --- Comment #20 from Mathias Nyman (mathias.nyman@xxxxxxxxxxxxxxx) --- There is another recent fix for a 5.12 regression related to giving back URBs: 9b6a126ae58d xhci: Fix giving back cancelled URBs even if halted endpoint can't reset It was added to v5.12.5 stable, so still missing from your 5.12.4 setup. Could you add that patch as well, and if it still doesn't help then take more detailed xhci traces and logs: mount -t debugfs none /sys/kernel/debug echo 'module xhci_hcd =p' >/sys/kernel/debug/dynamic_debug/control echo 'module usbcore =p' >/sys/kernel/debug/dynamic_debug/control echo 81920 > /sys/kernel/debug/tracing/buffer_size_kb echo 1 > /sys/kernel/debug/tracing/events/xhci-hcd/enable < connect the card reader and insert card > Send output of dmesg Send content of /sys/kernel/debug/tracing/trace note that trace file grows fast so copy the trace content somewhere soon after you see the first "reset SuperSpeed Gen 1 USB device" after failure.
