  1. I think I’ve got everything required, but whenever I try to set up the usb0 interface, I keep on getting error: device not found. I’m using a Galaxy Ace (GT-S5830) by the way.

    • I got this error device not found as well. But when I enabled USB debugging, Windows started downloading the Sony driver. I had to reboot the PC. But later, I restarted the procedure but the error message became “action ‘dhcp’ failed “

  2. i tried adb shell on my windows it said device not found
    and on the terminal on my android it says action failed (timer expired)
    is there any thing i’m missing?
    in my connections i selected both connection the Lan and the one tethered from my phone and right clicked and clicked bridge connections and it created new icon (network bridge) so what shall i be missing here!

  3. I have SGA 2.3.5. Bridge between local net and samsung OK, netcfg usb0 dhcp answer # (so OK), but open default browser and can not open google site.
    Type netcfg in emulator and apear an IP adress in usb line.
    Only works browser or can use other apps like whatsap?
