[android-developers] Re: Why ADB and DDMS cannot recognize my phone in Ubuntu?

Sorry that maybe I didn't describe my problem clear enough.

I follow the instructions in the below link:
http://coffeecokeandcode.blogspot.com/2009/12/android-debug-bridge-on-ubuntu-910.html

1. Find the VID and PID using lsusb
2. Add them into /etc/udev/rules.d/51.android.rules, and reload the
udev service
(I tried both "sudo service udev reload" and "sudo service udev
restart")
3. Restart the adb server in super user mode.
(sudo ./adb kill-server , sudo ./adb start-server under android-sdk
folder)

The adb shell commands works great actually, only "adb devices" shows
the phone name with ????????????,
and I cannot debug with ddms because it cannot find the device.
(But adb logcat works fine, I don't know what makes the difference
between ddms and adb logcat....)

P.S. I'm sure that I use stand alone ddms without Eclipse.
