EM7511 was not connected to the Jetson Module as well as the network.We install the GobiSerial & GobiNet then it show only one ttyusb port.If anyone knows the solution then please help.
Hi abhilashsl ,
Welcome you to our community!
Does your host have a QMI driver? Please refer to page 11 in Linux QMI SDK - Application Developers Guide - Rev2.0.pdf for how to install Gobi driver.

If it still happens please collect and send the log file like the below command:
sudo modprobe GobiSerial [debug=Y]
sudo modprobe GobiNet [debug=Y]
Enabling the driver’s diagnostic messages requires root privileges
#echo 1 > /sys/module/GobiSerial/parameters/debug
#echo 1 > /sys/module/GobiNet/parameters/debug
Open terminal and type tail -f /var/log/syslog
