Folks,<br><br></div>I am poking around with a new Sierra Wireless EM7355 in a Lenovo T440p. I've had two big problems getting it to work, one being easily solvable (<a href="https://bugs.freedesktop.org/show_bug.cgi?id=91351" target="_blank">https://bugs.freedesktop.org/show_bug.cgi?id=91351</a>).<br><br></div>The other problem is the "FCC Authentication" trick discussed here:<br><a href="https://bugzilla.kernel.org/show_bug.cgi?id=92101" target="_blank">https://bugzilla.kernel.org/show_bug.cgi?id=92101</a><br><br></div>That trick doesn't work on my modem because the EM7355 apparently doesn't support a QMI interface. It starts up in MBIM mode. I can switch it to QMI mode by setting bConfiguationValue in /sys/bus/usb/devices/1-10 to 1. The device reattaches with the proper ttyUSB devices. I can connect to ttyUSB2 with minicom and issue AT commands. The password A701 even lets me change the maintenance settings just fine. However, no QMI commands are possible.
