Device usb6/6-2 existed also before suspend: [ 2.444051] usb 6-2: new full speed USB device using uhci_hcd and address 3 [ 2.636033] usb 6-2: configuration #1 chosen from 1 choice There is not enough information to know what it is, but I guess it is (built-in?) smart card reader, based on [ 4251.276912] usb 6-2: usbfs: process 1360 (pcscd) did not claim interface 0 before use Compare lsusb -v output before and after resume. As for your modem - it seems to have dropped off after resume: [ 4251.624038] usb 6-1: new full speed USB device using uhci_hcd and address 4 [ 4251.744422] usb 6-1: device descriptor read/64, error -71 [ 4251.968059] usb 6-1: device descriptor read/64, error -71 [ 4252.184088] usb 6-1: new full speed USB device using uhci_hcd and address 5 [ 4252.304068] usb 6-1: device descriptor read/64, error -71 [ 4252.528099] usb 6-1: device descriptor read/64, error -71 [ 4252.744095] usb 6-1: new full speed USB device using uhci_hcd and address 6 [ 4253.160115] usb 6-1: device not accepting address 6, error -71 [ 4253.272083] usb 6-1: new full speed USB device using uhci_hcd and address 7 [ 4253.688067] usb 6-1: device not accepting address 7, error -71 [ 4253.688104] hub 6-0:1.0: unable to enumerate USB device on port 1 I would start with checking that device alone (without any application) can survive suspend/resume cycle. Stop NM/MM to make sure nothing attempts to attach to device; plug in modem; verify that it is available using lsusb; now suspend/resume and check whether modem is still available. If not - this is kernel problem and NM cannot do anything about it. > I've collected some logs here on Launchpad: > dmesg after resume: > http://launchpadlibrarian.net/53157289/dmesg > find in the sys directory after resume: > http://launchpadlibrarian.net/53157295/find > debug output for modemmanager: > http://launchpadlibrarian.net/53157338/mm.log > > Any chance to get modem-manager/networkmanager to rescan the device > tree to find the modem again? > > Torsten > > > _______________________________________________ > networkmanager-list mailing list > networkmanager-list gnome org > http://mail.gnome.org/mailman/listinfo/networkmanager-list
