Hello, I'm facing some issues to connect to my mobile phone (Sony Ericsson W660i) I use Gammu/Wammu to connect to my mobile phone With kernel 3.2 (debian wheezy) it works fine. But with kernel 3.16 (debian jessie) or even 4.0.2 it doesn't work. Moreover, the connection of the phone to the PC makes some configuration changes on my phone. It changes my netwok connection type from "2G only" to "2G/3G" for obscure reasons BTW, it seems the connection gets lost when the phone backlight turns off Here is the dmesg when I connect the phone [ 1536.912061] usb 3-2: new full-speed USB device number 2 using uhci_hcd [ 1537.168027] usb 3-2: New USB device found, idVendor=0fce, idProduct=d0a3 [ 1537.168035] usb 3-2: New USB device strings: Mfr=1, Product=2, SerialNumber=3 [ 1537.168040] usb 3-2: Product: Sony Ericsson W660 [ 1537.168044] usb 3-2: Manufacturer: Sony Ericsson [ 1537.168048] usb 3-2: SerialNumber: 3571550133112050 [ 1537.371402] cdc_ether 3-2:3.8 usb0: register 'cdc_ether' at usb-0000:00:1d.1-2, CDC Ethernet Device, 02:80:37:fa:02:00 [ 1537.371459] usbcore: registered new interface driver cdc_ether [ 1537.380242] cdc_wdm 3-2:3.7: cdc-wdm0: USB WDM device [ 1537.380282] usbcore: registered new interface driver cdc_wdm [ 1537.382752] cdc_acm 3-2:3.1: ttyACM0: USB ACM device [ 1537.387047] cdc_acm 3-2:3.3: ttyACM1: USB ACM device [ 1537.389890] usbcore: registered new interface driver cdc_acm [ 1537.389894] cdc_acm: USB Abstract Control Model driver for USB modems and ISDN adapters [ 1537.424010] cdc_wdm 3-2:3.7: wdm_int_callback - 0 bytes [ 1537.446697] cdc_ether 3-2:3.8 usb0: kevent 12 may have been dropped I already reported the following bug https://bugzilla.kernel.org/show_bug.cgi?id=100091 Is there anything to do ?
