EM7455 should be identical to MC7455?
Does it recognize any ttyUSB port or qmi?
You can check this post and to see if you can modify the model?
There is a package usb-modeswtich controlling model settings
root@GL-MT1300:~# opkg files usb-modeswitch
Package usb-modeswitch (2017-12-19-f40f84c2-2) is installed on root and has the following files:
/sbin/usbmode
/etc/usb-mode.json
/etc/hotplug.d/usb/20-usb_mode
/etc/init.d/usbmode
In /etc/usb-mode.json there are info about various modems.
For usb device, it has vendor ID and product ID. Can you find the vendor ID and product ID of your EM7455? I think you can find using lsusb
You can find Sierra modem usb identifier here USB\VID_1199 - Sierra Wireless, Inc. | Device Hunt
Maybe something can be done to modify these identifiers. But I don’t know how.
