UBX-13001118 - R25 System description Page 75 of 182
Each USB profile of LISA-U2 module 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].
If the USB interface is connected to the host before the module switch-on, or if the module is reset
with the USB interface connected to the host, the VID and PID are automatically updated at runtime,
after the USB detection. At first, VID and PID are the following:
VID = 0x058B
PID = 0x0041
This VID and PID combination identifies a USB profile where no USB functions are 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 (roughly 5 seconds, depending on the host / device enumeration timings),
the VID and PID are updated to the following values, which are related to the LISA-U2 module default
USB profile:
VID = 0x1546
PID = 0x1102
The default configuration of the USB interface provides 7 USB CDC-ACM modem COM ports:
USB1: AT and data
USB2: AT and data
USB3: AT and data
USB4: GNSS tunneling
USB5: Primary Log (diagnostic purposes)
USB6: Secondary Log (diagnostic purposes)
USB7: SAP (SIM Access Profile)
The user can concurrently use the AT command interface on one CDC, and Packet-Switched / Circuit-
Switched data communication on another CDC.
Figure 39 (left side) summarizes the USB end-points available with the default USB profile
configuration.
The USB interface of the LISA-U2 series can be configured by the AT+UUSBCONF command (for more
details, see the u-blox AT Commands Manual [2]) to select a different set of USB functions, available
in a mutually exclusive way, and including 1 CDC-ECM for Ethernet-over-USB and 4 CDC-ACM modem
COM ports enumerated as follows:
USB1: AT and data
USB2: GNSS tunneling
USB3: Primary Log (diagnostic purpose)
USB4: SAP (SIM Access Profile)
In the case of the USB profile with the set of functions described above, the VID and PID combination
is the following:
VID = 0x1546
PID = 0x1104
Figure 39 (right side) summarizes the USB end-points available with this alternative USB profile
configuration.
☞ The USB profile cannot be changed on the "01", "x2", "63" and "68" product versions of LISA-U2
series modules, as the AT+UUSBCONF command is not supported.
