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.
