!UDUSBCOMP
Supporting chipsets:
• All, with these exceptions:
• MDM8200 (min f/w rev:
M2.0 Release 1)
Set/report USB interface configuration
Use this command with modems that have been configured with multiple USB
compositions.
By default, devices are typically configured to use a USB composition that presents a
minimal set of interfaces. If the device also supports other compositions, this command
is used to choose from any of the supported compositions.
Note: MDM6270/MSM6290/QSC6270-based devices can use either their default VID/
PID (traditional interface, Direct IP not supported), or the Direct IP VID/PID (Direct IP
interface).
Usage:
• Execution: AT!UDUSBCOMP=<device_comp>
Response:
OK
Purpose: Set the current composition. For the change to take effect, you must
reset the modem.
• Query: AT!UDUSBCOMP?
Response:
!UDUSBCOMP: <device_comp>
OK
Purpose: Report the current interface composition.
• Query List: AT!UDUSBCOMP=?
Response: Example responses, details may differ:
Traditional interface:
0 - HIP DM NMEA AT MDM1 MDM2 MDM3 MS SUPPORTED
1 - HIP DM NMEA AT MDM1 MS NOT SUPPORTED
2 - HIP DM NMEA AT NIC1 MS NOT SUPPORTED
3 - HIP DM NMEA AT MDM1 NIC1 MS NOT SUPPORTED
4 - HIP DM NMEA AT NIC1 NIC2 NIC3 MS NOT SUPPORTED
5 - HIP DM NMEA AT ECM1 MS NOT SUPPORTED
OK
Direct IP interface:
0 - HIP DM NMEA AT MDM1 MDM2 MDM3 MS NOT SUPPORTED
1 - HIP DM NMEA AT MDM1 MS NOT SUPPORTED
2 - HIP DM NMEA AT NIC1 MS SUPPORTED
3 - HIP DM NMEA AT MDM1 NIC1 MS SUPPORTED
4 - HIP DM NMEA AT NIC1 NIC2 NIC3 MS SUPPORTED
5 - HIP DM NMEA AT ECM1 MS SUPPORTED
6 - DM NMEA AT QMI NOT SUPPORTED
OK
Purpose: Report the available interface compositions (<device_comp>)—the
device can use any of the compositions that are listed as
“SUPPORTED”.
Parameters:
<device_comp> (USB composition)
• Integer value, 0 or greater
• Use AT!UDUSBCOMP=? to view the configurations available for the device.
Available configurations are identified as “SUPPORTED”.
