(sorry for opening a new thread)
the device switches from
2357:0200
2357:0201
with
eject /dev/sr0
or the right usb_modeswitch-mesage, I saw one at this forum
This device works with "option" and "qmi_wwan".
I did not test dial in via ppp. (it should work - windows offers also a modem)
But the windows-dial-in-software uses this device as "ethernet" - which can be done under linux with qmi_wwan.
I tested qmi_wwan - it works (IPv4 -ok , IPv6 failed)
"option" and "qmi_wwan" don't know about the IDs of this device at the moment.
I think this will be changed, I sent some info to:
