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
[7] .
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 remote SIM Access Profile (SAP) 8
 CDC-ACM for diagnostic

RNDIS for Ethernet-over-USB
 CDC-ECM for Ethernet-over-USB
For example, the default USB profile configuration which provides 2 functions (1 RNDIS for
Ethernet-over-USB, and 1 CDC-ACM for AT commands and data) can be changed by means of the
AT+UUSBCONF command switching to a USB profile configuration which provides the following 6
functions:
 3 CDC-ACM for AT commands and data
 1 CDC-ACM for GNSS tunneling 9

1 CDC-ACM for remote SIM Access Profile (SAP) 10
 1 CDC-ACM for diagnostic
