The USB interface provides 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: diagnostic log
The user can concurrently use the AT command interface on one CDC, and Packet-Switched / Circuit-
Switched Data communication on another CDC.
For more details regarding USB capabilities, see the LARA-R2 series System Integration Manual [2].
USB drivers are available for the following Windows and Windows Embedded operating system
platforms:
 Windows 7
 Windows 8
 Windows 8.1
 Windows 10
 Windows Embedded CE 6.0
 Windows Embedded Compact 7
 Windows Embedded Compact 2013

LARA-R2 series modules are compatible with the standard Linux/Android USB kernel drivers.
2.5.3 HSIC interface
☞ The HSIC interface is not supported by “02” and “62” product versions except for diagnostic
purposes.
LARA-R2 series modules include a USB High-Speed Inter-Chip compliant interface with a maximum
480 Mbit/s data rate as per the High-Speed Inter-Chip USB Electrical Specification Version 1.0 [16]
and USB Specification Revision 2.0 [15]. The module itself acts as a device and can be connected to
any compatible host.
The HSIC interface is available for communication with a host application processor (AT commands,
data communication, FW update by means of the FOAT feature), for FW update by means of the
u-blox EasyFlash tool and for diagnostics.
The HSIC interface consists of a bi-directional DDR data line (HSIC_DATA) for transmitting and
receiving data synchronously with the bi-directional strobe line (HSIC_STRB).
The modules also include the HOST_SELECT pin to select the module / host application processor
configuration: the pin is available to select, enable, connect, disconnect and subsequently reconnect
the HSIC interface.
