`import pyb` imports the pyb module, that let's you access the functions and methods for controlling the pyboard. `pyb.usb_mode()` let's you set as what kind of device the pyboard should act if connected to USB. `'CDC+HID'` means 'Human Interface Device' - in this mode the board is recognized as if it where a mouse or keyboard. In this example, this only means that it is NOT recognized as mass storage device, so the file system doesn't get mounted.

The problem is, now we can't access the filesystem anymore, so you'd have to remove the SD-card and put it into a SD-card reader to get back your data or to change the scripts again. Now, if we set `pyb.usb_mode()` back to `'CDC+MSC'`, the pyboard would act as SD-card reader. So, we use the switch to change between these modes. After reset, you have a short time window. If the switch is pressed and hold, the board acts as mass storage, if not it acts as Human Interface Device.
