Title:
  xhci_hcd fails detecting SD-cards

Status in “linux” package in Ubuntu:
  Expired

Bug description:
  I've got a multi card reader in my PC connected to an USB 3.0 slot.
  When I plug in an SD-card and copy some pictures from my SD-card to
  the local drive, everything works fine. But when I remove the SD-card
  and plug in the same or any other SD-card no device/drive is detected.
  The syslog only shows the following output:

  Dec 26 13:20:50 bender kernel: [ 1691.981335] xhci_hcd 0000:03:00.0: WARN Event TRB for slot 1 ep 3 with no TDs queued?
  Dec 26 13:20:50 bender kernel: [ 1691.981409] xhci_hcd 0000:03:00.0: WARN Event TRB for slot 1 ep 2 with no TDs queued?
  Dec 26 13:20:50 bender kernel: [ 1691.981488] xhci_hcd 0000:03:00.0: WARN Event TRB for slot 1 ep 0 with no TDs queued?
  Dec 26 13:20:50 bender kernel: [ 1692.085341] xhci_hcd 0000:03:00.0: WARN Event TRB for slot 1 ep 0 with no TDs queued?

  Interestingly USB sticks are still detected on the same USB 3.0 port, but SD-cards not.
  To be able to detect SD-cards again I have to reboot the PC.
  This bug only shows up when I copy some files. When I only plug in and remove SD-cards several times this bug does not occur.
  For me it seems to be a bug in the data transfer code for SD-cards.
