I have tried to connect my EM7565 to my computer with a m.2 to usb adapter, but when I do the device only shows up as an unknown usb. No additional com ports. I have tried to uninstall and reinstall many different Sierra Wireless drivers to get it to recognize the EM7565 but still nothing works. Is there anything I can do or is the modem completely bricked?

I also tried lsusb in ubuntu and Sierra Wireless is not showing up. Last, I tried usb-devices and got the same result.

Update: attempted to find if the computer can communicate with the modem and it completely fails. sudo dmesg | grep cdc comes back with nothing. Running sudo tail -f /var/log/syslog and watching when I plug in the modem I get a failed result to connect:

"ubuntu@ubuntu:~$ tail -f /var/log/syslog

It appears I have somehow completely bricked the modem and there is absolutely no communication with it anymore.

All I attempted to do is get it into MBIB mode by running:  
AT!ENTERCND=“A710”  
AT!USBCOMP=1,3,1009  
AT!RESET

And yes I am sure I typed 1,3,1009 and not 1,1,1009.
