I'm running 12.04 and I have a Creative X-fi "cardbus" sound card. It works fine if I boot the computer with the card already inserted; but if I insert it after boot, it is not detected. Also dmesg shows absolutely nothing after inserting the card. It was working on Ubuntu 11.04. Is there anything I can do to make it auto-detect again? Failing that, any command I could issue to manually make the computer detect it without having to reboot?
Update: I tried to add "pcie_aspm=force" to the boot options (someone told me it might help) but nothing changed.
