usb bus 6 trace 5.12+patch

Hi Mathias, thanks for your patch.

I applied the patch to v5.12.4 and it applied just fine, but the card reader is
still not working.
So sadly I have to report that the issue is not fixed with it, but I spotted a
few differences with it.
I recorded new traces and it seems the trace log for bus 6 is a lot smaller
than it was without the patch, but the symptoms are very much the same.
After plugging in the display / card reader, it seems to be detected fine
according to dmesg until

Inserting the card once did not change anything in dmesg, so I ejected and
re-inserted it. The second time I also got

[   98.068827] usb 6-2.3.1: reset SuperSpeed Gen 1 USB device number 4 using
xhci_hcd
[   98.096880] sd 6:0:0:0: [sdb] Attached SCSI removable disk

But still no partitions (which are present) detected and cfdisk fails just like
before.
What seems different now is I am seeing a lot less errors in dmesg, but
repeated
