Android Device Chooser — device not showing up

Does anybody have an idea what I may be doing wrong. I have installed the usb drivers and have my device running in debugging mode but when I run my basic hello world application through eclipse my device wont show up in the device chooser. I h开发者_开发技巧ave also tried re installing the sdk and all the drivers and still no luck. Thanks to anybody that can help me out

I had this problem (on Linux). Running 'adb start-server' manually as root solved it for me.

my nexus one does this to me sometimes. I have to toggle debug mode on the phone off/on and sometimes I even have to reboot the phone to fix it. Usually when this happens I type

adb devices

My phone will actually show up in the list but say 'offline'

This problem comes up often. Restarting the ADB server solves this problem most of the times.

I had the same problem. Although it was working fine for a long time it suddenly sopped working. I tried to reinstall driver, reboot phone, pc, restart adb server etc but nothing worked. At the end I was able to fix it by going to device manager -> properties -> update driver! I wonder why reinstalling driver didn't solve.
