USB Ports not working anymore after 10.10 DP5 Update


So guys, I've successfully installed Yosemite 10.10 on my laptop and it worked fine until I downloaded an update from the Mac App Store to the DP5 and then the usb ports stopped working. There was no graphic acceleration or sound either until I patched the DSDT provided by Rehabman. Except for the usb ports, the rest of the components are working fine. Is there any workaround or DSDT patch to get the usb ports working. Also I updated to yosemite over Niresh Mavericks and I have Synaptics touchpad. Multitouch gestures seem to work, but I can't click or drag. 

Thanks in advance

My system specs
Sony Vaio E series
Intel Core i3 2.39 GHz
Intel HD 3000 onboard graphics
