Hi Bjorn,
my have a new USB 3G modem sold in Czech Republic by T-Mobile. So far it works for me only using the option driver and pppd. The 'qmi-network /dev/cdc-wdm0' does not work for me. Maybe it has no QMI interface ('modprobe qmi_wwan' does not log any new device found through dmesg but maybe that is because it is already claimed by cdc_ncm driver)? I haven't seen the virtual CD-ROM associated media errors with my old Huawei E372. I believe I can ignore them but is that because of the modem firmware being ... suboptimal? BTW, usb_modeswitch used to log that it flipped a device. Isn't this needed anymore?
Here is what is logged on linux-4.1.3 kernel:
