This VID and PID combination identifies a USB profile where no USB function described above is available: AT
commands must not be sent to the module over the USB profile identified by this VID and PID combination.
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:
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)
o
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 24 summarizes the USB endpoints available with the default USB profile.
