running adb from command line makes the device go offline

Question

I have a strange problem where everytime I run adb from command line (devices command or pull, or uninstall etc), the device goes offline but if I now go into DDMS in eclipse and reset ADB, it comes back online. If I am running the game from within eclipse, it runs (by which I mean my Eclipse DDMS is able to use adb just fine) but from command line, doing anything adb-related brings the device offline and the only way to bring it back online is adb reset from DDMS inside eclipse. Effectively, I cannot do anything adb-related through command line.

I have tried solutions like switch the debug option of device on and off, adb-kill-server and then start-server, android 51 rules file, and more weirder solutions like change cable, change port etc. Many of those bring the device online, but whenever I run a adb command from the terminal, poof! device is back offline.

I have been facing this for over a month now and I have done all research I could, on google and on stackoverflow but nothing have I found which could address this specific issue.

Any help is appreciated. Thanks.

The problem is that you are having two version of adb in your computer. Remove adb.exe,AdbWinApi.dll and AdbWinUsbApi from C:/Windows and everything will be fine.
