Thx. I had used those patches in the past till Zenith released his Generic USB3 kext which was much more elegant in usage than patching. But as everyone is finding out, that kext does not work with 10.10.
The patch you posted above does not work as it has bugs (missing </dict> and missing "Find"string).
Only question is whether these patches work on the next update release ?
Sorry for those bugs, happened because I took only the patches for USB fixes among my other "Kernel and Kext patches"
