Maybe an xhci-hcd maintainer would be able to interpret = the log better, but I can't. However, the repeated 0x341 and 0x2a0 port-status values are new. They indicate that the card reader is behaving in some strange way, different fr= om what it was doing before. --=20 You may reply to this email to add a comment.
