I removed dart then reboot my computer. My USB ports wake up with DMAR. I have an external USB Audio adapter and the music resumes after sleep.
There is no issue with 4540s (Ivy) and USB... it is already using AppleUSBXHCI.kext with DSDT patches.
I think there may be some attempt to apply the same changes I'm recently using on my u430 to use AppleUSBXHCI instead of GenericUSBXHCI on the Haswell models supported by the ProBook Installer.
