Answer 1

I had the same problem - Try to use a different USB port. From my experience, the USB connections on the PC front are not recommended.

Answer 2

I was using a USB 3.0 port too and a device Xoom with ics 4.0. To solve my problem, I needed to restart my Windows, because in the DDMS my device was showed twice. After the restart, I needed to change the USB port to a 2.0 USB port and it work for me.

Answer 3

Year almost 2018 I just had same problem which doubled my gray hairs. It turned out my test phone Samsung Galaxy S6 does not like the USB ports on my Apple Thunderbolt Display. I just plugged the USB cable directly to my Mac Pro and it worked right away. Funny thing is my Google Pixel Phone never complains about the USB port on Thunderbolt.

Answer 4

restart your dev machine, worked for me :)

Answer 5

To keep the error message from showing up I did the following on Eclipse 3.7:

• Window->Preferences
• On the left side tree select Android->DDMS
• In the DDMS settings window choose logging level "Assert"
• Click "Apply"

Answer 6

ok so here's what fixed it for me and I think this is retarded that I have to do this. I'm on Windows 7 64 bit, but maybe 2 or 3 times during the day I get this same error. I tried the reboot thing sometimes it worked, sometimes it does not...

I have to:

1. Close Eclipse
2. Unplug USB
3. Open task manager and find the "adb.exe *32" and End Task
4. Open Eclipse (not done yet)
5. "Clean All" (clean all not just project)
6. Then build the project (for me just building the project works)
7. Plug USB back in and there ya go!

Always works for me. Like I said retarded, Android dev sucks, but makes money... iPhone/xCode is BETTER!

If anyone knows of an update to something I can down load to avoid doing this all the time, I'd love to know!
