TOBY-L2 and MPCI-L2 modules provide by default the following USB profile with the listed set of USB functions:

 1 RNDIS for Ethernet-over-USB connection

 1 CDC-ACM for AT commands and data communication

The USB profile of TOBY-L2 and MPCI-L2 modules identifies itself by its VID (Vendor ID) and PID (Product ID)

combination, included in the USB device descriptor according to the USB 2.0 specifications [6].

The VID and PID of the default USB profile configuration with the set of functions described above (1 RNDIS for

Ethernet-over-USB and 1 CDC-ACM for AT commands and data) are the following:

 VID = 0x1546

 PID = 0x1146

Figure 19 summarizes the USB end-points available with the default USB profile configuration.

The USB of the modules can be configured by the AT+UUSBCONF command (for more details see the u-blox AT

Commands Manual [3]) to select different sets of USB functions available in mutually exclusive way, selecting the

active USB profile consisting of a specific set of functions with various capabilities and purposes, such as:

 CDC-ACM for AT commands and data

 CDC-ACM for GNSS tunneling

 CDC-ACM for SIM Access Profile (SAP)

 CDC-ACM for diagnostic

 RNDIS for Ethernet-over-USB

 CDC-ECM for Ethernet-over-USB

 CDC-NCM for Ethernet-over-USB

 MBIM for Ethernet-over-USB

CDC-ACM for GNSS tunneling, CDC-ACM for SIM Access Profile (SAP), and CDC-NCM and MBIM

functions are not supported by the TOBY-L2x0-00S and MPCI-L2x0-00S product versions.
