Subject: [Regression] USB tethering does not work anymore in 2.6.29-rc2 (rndis_host, does not receive DHCP offer anymore)
Date: Thu, 7 Apr 2011 04:11:27 +0200 [thread overview]
Message-ID: <BANLkTim8anqNv4MEaxCTyC8HyOZp2x=ixQ@mail.gmail.com> (raw)
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

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.
