Hi, Try to re-test with 8-stable or 9-current (kernel+kernel modules only). We had some EHCI fixes go in for certain chipsets, due to what appears to be hardware bugs. So far there has been very few bugs in the EHCI driver. Try to compare verbose output, and see that the pnpinfo is identical! --HPS
