Look in system.log for USB related messages that might help troubleshoot the problem.
Also,
Please provide complete details in your profile/signature
(Profile/Settings link in upper right corner of this site)
System: manufacturer/model
CPU: detailed CPU model + motherboard chipset
Graphics: all graphics devices + laptop internal screen resolution
For example, typical Ivy laptop:
System: HP ProBook 4540s
CPU: i5-3320m/HM76
Graphics: HD4000, 1366x768
Use CPU-Z on Windows to find CPU (Core iX-xxx) and motherboard chipset (HMxx), and graphics capabilities. For a laptop, these details are important and affect critical installation procedures.
OK I figured out the cause but don't know how to fix it. None of my USB ports work. I'm using your series 6 USB dsdt patch with GenericUSBXHCI boot flag defer usb2. I had to install this kext and edit DSDT because my system would not sleep without it.
