I know this is old, but just in case... seems that USB3 doesn't always play nice with ADB, so if nothing else helps try a USB2 port...

HTC Sync Manager has adb.exe at location C:\Program Files\htc\htc sync manager\htc sync\adb.exe

You have 2 options now:-
1) Delete this adb.exe
2) Copy latest adb.exe from android sdk to this path.
Note: You need to make the 2 copies of adb.exe in sync always(when android sdk is updated) else this problem will come up again.
On windows 7, you can make a link of adb.exe from android sdk to this folder, which will avoid copying manually.
C:\> cd "C:\Program Files\htc\htc sync manager\htc sync"
C:\Program Files\htc\htc sync manager\htc sync\> mklink adb.exe C:\<path to your sdk>\platform-tools\adb.exe

Three years later, having this problem, and this was the issue! Thanks for the fix :D

    The ADB server binds and listen to port 5037. If that port is taken and/or if the daemon is already running, you'll see that error message.

    Start task manager and kill adb.exe (all the instances of it).

    If that don't work, try rebooting your computer and your phone, and trying again.

    If it still don't work, try this:

    Somebody please help me out of my misery. I followed the rooting directions to the letter, but when I type "adb devices" I get the following error:

    * daemon not running. starting it now *
    ADB server didn't ACK
    * failed to start daemon *
    error: cannot connect to daemon

    I'm in the right directory ( AndroidSDK\tools\ ), I have the android driver installed, I have USB debugging checked, I don't understand why this is not working.

    Please help me out here.

    I had no problem rooting my palm pre, which was infinately more complicated than this.

    Thank you in advance.

    had a pre and "rooted" it as well..... using putty is more complicated that this but this is a little more like hacking... whereas on the pre you are just accessing root rather than breaking into it.


    anyway... try these

    nstall htc sync from htc's website, can you sync?

    run cmd as administrator

    cd untill you are in the same directory as your adb

    type "adb devices"

    does it display your hero?

    type "adb shell"

    does is display "$" ?

    Just for help :

    I had the same issue and it was my Firewall which blocked the starting of deamon.
    Turn off your Firewall can fix the problem

    Problem is HTC Sync

    This solved it for me:

    Edit ~/.android/adb_usb.ini file to make sure that there is no extra empty line after the 0x0006 line entry


    For other users: I also found this:
