No, that did not help (tried on 3.4-rc3). First I plugged in the NEC uPD720200 USB3.0 card and unplugged it (card removal not reported :(), saved the lspci output. Then I inserted the FireWire card, unplugged, again saved the lspci output. Finally, saved the dmesg. All three files are attached. Thank you for your time, Martin
