[PATCH] USB: serial: option: the patch is meant to support LARA-R6 Cat 1 and LARA-L6 CAT 4 module family.

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The LARA-R6 module has the following USB identifiers:
Vendor  ID: 0x05c6
Product ID: 0x908b

The USB composition exposes the following interfaces:
If 0: Diagnostic
If 1: AT parser
If 2: AT parser
If 3: AT parser/alternative functions

The LARA-L6 module can be configured in three different USB modes: 
* Default mode (Vendor  ID: 0x1546 Product ID: 0x1341) with 4 serial 
interfaces
* RmNet mode (Vendor  ID: 0x1546 Product ID: 0x1342) with 4 serial 
interfaces and 1 RmNet virtual network interface
* CDC-ECM mode (Vendor  ID: 0x1546 Product ID: 0x1343) with 4 serial 
interface and 1 CDC-ECM virtual network interface


In default mode LARA-L6 exposes the following interfaces:
If 0: Diagnostic
If 1: AT parser
If 2: AT parser
If 3: AT parser/alternative functions

In RmNet mode LARA-L6 exposes the following interfaces:
If 0: Diagnostic
If 1: AT parser
If 2: AT parser
If 3: AT parset/alternative functions
If 4: RMNET interface

In CDC-ECM mode LARA-L6 exposes the following interfaces:
If 0: Diagnostic
If 1: AT parser
If 2: AT parser
If 3: AT parset/alternative functions
If 4: CDC-ECM interface
