Kernel Panic error from USB drivers

[twitchel]

Hi All,

 

I had iATKOS v7 working awesomely on my laptop (HP Pavilion DV5 1139tx)

 

I tried installing the USB drivers and Cardbus drivers that came on the iATKOS disc to try and get my USB ports and card reader working

 

now it wont boot up

 

Last thing that comes up on screen is

 

USBF: 5.701 AppleUSBUHCI: unable to initialize UIM

Reloading IOCatalogue

 

How can i remove these kexts which were installed?

 

Thanks
