Thank you so much for these kexts! I tried and failed at modifying my DSDT file to have my OHCI USB devices recognized as built-in and consequently I couldn't sleep. With your IOUSBFamily kext, however, all my devices appear as built-in and sleep works!

I have one small problem though with the USB3 controller support provided by the xHCI kext. After I installed the CalDigitUSBxHCl kext, the USB 3.0 ports on my Asus U3S6 pci-e card would be recognized and are visible in the system profiler but they would not function. Furthermore the Kext would break sleep with the Asus U3S6 pci-e card installed. Using the default IOUSBFamily and the modified Lacie kext (PXHCD.kext) would give me full USB 3.0 support at the cost of sleep and the OHCI/EHCH fixes. Trying to use both your modified IOUSBFamily and the Lacie kext results in a kernel panic that is no doubt due to a conflict between the two drivers. Do you have any idea how to resolve my problem with USB 3.0 support and sleep functionality?
