The SIM accepts the PIN and after a while the motdem resets itself and disappears from the usb bus, to show up after 1-2 seconds again. If I do it to often, the Modem changes its product_id to 9040 and has only 1 Interface (udev loads qcserial) and only 1 bConfiguration Value. And it doesn't work at all, the only thing which helps is to remove all power supply.After that it shows up with the product_id 9041 again. Kernel Version is 4.5.7 When I Try to run the modem in mbim mode, I'll get this messages: Jul 12 16:33:37 ThinClient kernel: usbcore: registered new interface driver cdc_ncm Jul 12 16:33:38 ThinClient kernel: usbcore: registered new interface driver cdc_wdm Jul 12 16:33:38 ThinClient kernel: cdc_mbim 3-11:2.12: cdc-wdm0: USB WDM device Jul 12 16:33:38 ThinClient kernel: cdc_mbim 3-11:2.12 wwan0: register 'cdc_mbim' at usb-0000:00:14.0-11, CDC MBIM, a6:b5:9c:ec:6b:b5 Jul 12 16:33:38 ThinClient kernel: usbcore: registered new interface driver cdc_mbim Jul 12 16:33:38 ThinClient ModemManager[2100]: opening device...
