Tried using it on Freebsd but it wasn’t being detected at all by the kernel, so I plugged it into a Windows 10 device which did detect it but then after messing with drivers and installing this (driver)[https://source.sierrawireless.com/resources/airprime/software/usb-drivers-build-4836/] , the modem wasn’t being *detected at all by either OS.
Have I bricked the MC7304?
*By detected I mean, it’s not even appearing as a device in device manager etc.
Unless you are trying to download new firmware then it is highly unlikely you have bricked the unit (even then you would have to put some effort in).
I would suggest trying to plug it into a Linux system and sending the ‘lsusb’ command as this will show the very low level USB declaration to the system of the unit, no drivers required and it will show if the unit is powering up. How are you powering the unit?

An external mpcie - USB adapter with a sim card slot, got 2 different ones to try out and both seem to be drawing power.
Though I did just try reinstalling drivers with Sierra Wireless Watcher and now I have 3 Sierra Application Interfaces com ports visible now in Windows and 1 diagnostic interface. There is also a “Sierra Wireless Aircard HSDPA Modem” now listed in device manager but can’t get any response from it.
They’re being exposed by the virtual serial port driver, so I still think the modem itself isn’t powering on.
