[Resolved]Mavericks, USBF: [number] We could not find a corresponding USB EHCI controller for ...

[yazoox]

firstly, I installed a win7 on a virtualbox, 

then, create a new .vdi (create 2 partition, one is for image of mavericks 10.9.1, the other is for install mac)

install chameleon 2281 for windows. 

reboot, use chameleon to boot. choose "install mac os x" 

 

then I hit the following errors. 

 

USBF: [number] We could not find a corresponding USB EHCI controller for our OHCI controller at PCI device number6

 

 

I fixed this issue by changing the settings of virtual box
