Comment 29 for bug 1940377

There are 2 usable configurations in 12d1:15c1, cfg#2 which is cdc_ether and cfg#3 which is cdc_mbim , usb_modeswitch will select the linux preferred mbim configuration if mbim drivers are present in the kernel. This is by design and not a bug.

A user who prefers cdc_ether can disable the the automagic mbim switch by changing the line DisableMBIMGlobal=0 to DisableMBIMGlobal=1 in /etc/usb_modeswitch.conf, there is really no need to revert to an older usb_modeswitch version in order to disable the mbim auto selection.
