This apparently started with the fix for bug 1169332.
I haven't been able to reproduce locally yet. I'll keep an eye on this failure.

Ok, I can reproduce this locally too, after doing a test run like this.
The device can't suddently be found after a while.

Now I remember I've seen this issue myself before, that I couldn't find the device anymore after a while. I then would unplug and replug the usb cable and the device would be found again.

Please ignore comment 1, that was meant for bug 1172343.

This is how the homescreen looks like when this happened. Apparantly all the icons haven't been loaded yet.

This will probably be fixed by bug 1172497.
