Wireless-testing is a kernel about wireless card or something related, but why 
there is a file named usb.c? Is it related to usb? Hope who can answer it to me. 
Thank you so much.

Wireless-testing is a complete tree, thus it has every file that is found in the 
mainline tree. There are a number of files named usb.c. To know what it does, 
you would need to tell what path it is in. In general, a file named usb.c would 
contain the interface between a device and the USB system.

The differences between wireless-testing and mainline are related to the 
development. New material comes through wireless-testing and goes through 
several trees before if is merged into mainline. Usually wireless-testing is 
about 1 version newer than mainline.

Thank you so much for the reply. I am so appreciated.

I am still a little confused. Would you please set an example for 
drivers/net/wireless/rtlwifi/usb.c ?

That contains some of the code for dealing with USB RTLWifi devices.

That file contains the USB-specific low-level routines for the driver used by 
the RTL8188CU devices built by Realtek. If you want to know what that file does, 
read the comments.
