Then, after a time period (which depends on the host / device enumeration timings), the VID and PID are
updated to the ones related to the default USB profile providing the following set of USB functions:
 6 CDC-ACM modem COM ports enumerated as follows:
o USB1: AT and data
o USB2: AT and data
o USB3: AT and data
o USB4: GNSS tunneling
o USB5: SAP (SIM Access Profile)
o USB6: Primary Log (diagnostic purpose)
VID and PID of this USB profile with the set of functions described above (6 CDC-ACM) are the following:
 VID = 0x1546
 PID = 0x110A
Figure 22 summarizes the USB end-points available with the default USB profile.
