<div dir="ltr">Hello all, <div><br></div><div>I am developing an application making use of libmm-glib high level API and I am using a EM7455 Sierra Wireless modem. </div><div><br></div><div>At the moment the modem is working under MBIM mode (usb-composition) and I have created a <font face="monospace"><i>udev rule</i></font> so that the ModemManager ignores the modem's AT port (
USB_INTERFACE 3) and I am able to send specific configuration commands to it:</div><div><br></div><div><font face="monospace">SUBSYSTEM=="tty",ACTION=="change|move",ENV{ID_VENDOR_ID}=="1199", ENV{ID_USB_INTERFACE_NUM}=="03", ENV{ID_MM_PORT_IGNORE}="1"</font></div><div><font face="monospace"><br>SUBSYSTEM=="tty", ACTION=="add", ENV{ID_VENDOR_ID}=="1199", ENV{ID_USB_INTERFACE_NUM}=="03", ENV{ID_MM_PORT_IGNORE}="1", RUN+="/etc/udev/scripts/my_script.sh"</font><br></div><div><br></div><div>The issue I am experiencing , which I don't know if it may be related with this, is that <b>in some cases</b> (even after a host system reboot) the <b>ModemManager is not able to list my modem</b> (<font face="monospace"><i>mmcli -L</i></font>), even though it is available in the system via <font face="monospace" style="font-style:italic">lsusb </font><font face="arial, sans-serif" style="">command.
