I got a EM7455 on an M2 adapter in a housing, and managed to update it with
SWI9X30C_02.38.00.00_GENERIC_002.082_000.nvu. Initially it was showing this:
OK AT!ENTERCND="A710" OK ? DW5811e Snapdragon™ X7 LTE OK AT!USBPID? !USBPID: APP : 81B6 BOOT: 81B5 OK AT!USBPRODUCT? DW5811e Snapdragon™ X7 LTE OK AT!PRIID?

Did not run
AT!RESET. Now when the device is connected over USB, it doesn’t create any TTY or CDC interfaces, and this is only printed in dmesg:
usb 1-3: new high-speed USB device number 19 using xhci_hcd usb 1-3: config 1 has an invalid interface number: 8 but max is 3 usb 1-3: config 1 has no interface number 1 usb 1-3: New USB device found, idVendor=1199, idProduct=81b6, bcdDevice= 0.06 usb 1-3: New USB device strings: Mfr=1, Product=2, SerialNumber=3 usb 1-3: Product: EM7455 usb 1-3: Manufacturer: Sierra Wireless, Incorporated usb 1-3: SerialNumber: LFXXXXXXXXXXXXXX
Ubuntu 22.04, kernel 6.1, the Gobi DKMS drivers do not compile for me. Is there anything I can do to make the card reset to a default profile?
