Maybe it is a stupid question: What is the meaning of bisect in here?

Sorry, I' m honestly not knowledgable enough about the DSDT content so I just managed to use the 
"Device (XHCI)" node to support the xhci controller to work and remove the previous "Device (USB0)"
node. 

If you have time to discuss it, I'm glad to continue to fix and improve my patches. And I will go on to improve
myself and learn from experienced experts like yours.

Many thanks
Yuquan
