Example screen grab of before and after second device attached

Description of Problem:
If a second Android Android device is connected (via USB) the XS loses some connection information on one of the Devices and either, or both devices, cannot then be debugged. I have a Nexus 7 and HTC Desire, each of which can be debugged if only one is connected at a time.

Steps to reproduce the problem:
1. Connect an Android Device to USB (I use Google Nexus 7)
2. Connect second Android Device to USB (I use HTC Desire)
(I would suggest that you may have to restart XS between each operation)

Actual Results:
First Android Device details lost in the XS

Expected Results:
I would expect BOTH Android Devices to be fully recognized, and potentially debuggable

How often does this happen? 
Every time I connect two Android devices to two USB ports

Additional Information:
You will notice from the screen grab that the Google Nexus 7 (05865C1) becomes Android Device (058651c1), and as an 'Android Device' it cannot be debugged.
I suspect that this situation occurs with earlier XS versions.

Can you please attach the AndroidTools log for this session? You can find long files in Help -> Open Log Directory.

This may be an issue in adb, all I can tell from the logs is that we're losing the TCP connection to adb.

Is there any specific pattern to when it happens?
Comment 4 Greg Munn 2015-09-18 13:52:42 UTC
@Tony, are you able to tell me if this is an ongoing issue for you? We have made many different changes to handle ADB vagaries and I've not ever been able to reproduce this particular one.

If this is still an issue, please reopen the bug with as much information as you can provide, including the AndroidTools log from Help | Open Log Directory.
