[USB] devices not recognized Problem with IOUSBHIDDriver.kext

[hadyhallak]

installed mavericks on my hp dv6 laptop

and usb devices are not recognized : (USB Mouse and Keyboard, Internal Camera)
but any other USB Flash works

this happens only when I put UseKernelCach=Yes

I booted with 2 ways(UseKernelCach=Yes|No)
and compared the related usb kexts were loaded in 2 ways
I found out that this extension is loaded without using the KernelCache :

IOUSBHIDDriver.kext
Located in : S\L\E\IOUSBFamily.kext\Contents\PlugIns\IOUSBHIDDr iver.kext

when this kext is loaded usb camera , mouse and keyboard works!

Any help would be appreciated.

[Solved]

Well I found out that 2 ports are working
I removed S/L/E/AppleHPET.kext and now I have every thing working

Maybe you need DSDT patch for HPET. See: https://github.com/RehabMan/Laptop-DSDT-Patch
