I can't piece together everything the thread is talking about, but it may job someone's memory. I can also try e-mailing the author of that thread directly. When it's cold-booted under Linux, can you grab 'lsusb -v -d 1199:901F'? Also grab 'dmesg' output to see what driver messages there are. Next, if you have mbimcli installed, run 'sudo mmcli --firmware-list -m 0' and lets see what we have. Next warm-boot from Windows to Linux and run 'sudo mmcli --firmware-list -m 0' in case the previous one didn't work. Dan Thank you for your reponse, Dan. I've attached the information you asked for to this e-mail, formatted in a way it can be easily diff'd/vimdiff'd at your leisure.

I can no longer actually query the device using qmicli anymore under any condition... every attempt times out or returns: [29 Jan 2015, 10:23:06] -Warning ** [/dev/cdc-wdm0] QMI framing error detected I will try and resolve these and get you an answer. Also: the code you added in qmi_wwan never even gets evaluated AT ALL until I switch the device into the mode (via the sysfs echo) that exposes the serial ports; does that sound backwards to you, too? That sounds odd; is your device driven by MBIM or QMI here? At least on most Sierra devices with either DirectIP or QMI support, they will also expose a couple serial ports too. Which mode are you in to start with, and which mode are you switching too, and how are you doing that via sysfs? Note that if this device is like the MC77xx, then it will switch control protocol based on protocol snooping and *not* the selected USB descriptors. So if you probe it as MBIM then it becomes MBIM, regardless of whether it is driven by cdc_mbim or qmi_wwan. It does not really support switching modes without being completely reset. You should let udev select a mode as soon as it is discovered and stick with that.
