Hello, I am using an Android phone connected over USB to connect to the internet. Something in -rc2 broke this, as I am not getting connections through NetworkManager anymore (it doesn't receive a DHCPOFFER anymore and times out). This does work on the -rc1 kernel and is 100% reproducible here (same USB port, rebooting the phone between tries). dmesg is about the same in both cases (the usb-storage is here as the phone frist tries to act as a mass storage device after connect and I have to manually activate a checkbox to switch to tethering functionality): [ 235.150385] usb 1-3: new high speed USB device number 3 using ehci_hcd [ 235.320523] scsi2 : usb-storage 1-3:1.0 [ 235.801209] usb 1-3: USB disconnect, device number 3 [ 236.200390] usb 1-3: new high speed USB device number 4 using ehci_hcd [ 236.452982] usbcore: registered new interface driver cdc_ether [ 236.473241] rndis_host 1-3:1.0: usb0: register 'rndis_host' at usb-0000:00:12.2-3, RNDIS device, 06:0f:e2:6a:61:cd [ 236.474151] usbcore: registered new interface driver rndis_host [ 236.487433] usbcore: registered new interface driver rndis_wlan [ 246.850094] usb0: no IPv6 routers present lspci is at http://sukzessiv.net/x120e , let me know if you need any more info. cheers, gohai Below the full NetworkMonitor output of the working (-rc1) case and below the failing (-rc2) one. I noticed the different ifindex in line two, but other than that I don't see any difference except the obviously missing DHCPOFFER. -- begin working (-rc1) -- NetworkManager[1958]: <info> (usb0): carrier is OFF NetworkManager[1958]: <info> (usb0): new Ethernet device (driver: 'rndis_host' ifindex: 5) NetworkManager[1958]: <info> (usb0): exported as /org/freedesktop/NetworkManager/Devices/2 NetworkManager[1958]: <info> (usb0): now managed NetworkManager[1958]: <info> (usb0): device state change: 1 -> 2 (reason 2) NetworkManager[1958]: <info> (usb0): bringing up device.
