In Telit plugin we only probe the port with ID_USB_INTERFACE_NUM == 00,
which we know that supports AT commands, see mm-common-telit.c:
286 /* Try to get a port configuration from the modem: usb interface 00
287 * is always linked to an AT port
288 */
289 port = mm_port_probe_peek_port (ctx->probe);
290 if (!ctx->getportcfg_done &&
291 g_strcmp0 (mm_kernel_device_get_property (port,
"ID_USB_INTERFACE_NUM"), "00") == 0) {
292
293 if (ctx->getportcfg_retries == 0)
294 goto out;
295 ctx->getportcfg_retries--;
296
297 mm_port_serial_at_command (
298 ctx->port,
299 "AT#PORTCFG?",
300 2,
301 FALSE, /* raw */
302 FALSE, /* allow_cached */
303 ctx->cancellable,
304 (GAsyncReadyCallback)getportcfg_ready,
305 ctx);
306 return;
307 }
