--- Comment #20 from Mathias Nyman (mathias.nyman@linux.intel.com) ---
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.

Thanks
