I am developing an app for a new Android device (on all other I've never had this issue).
It's running 4.2.2 I have enabled developer mode and allowed usb debugging (I receive the status notification that usb debugging enabled)
However, in chrome://inspect the screen keeps alternating between the below two messages, seems it can't make up it's mind!
I've tried unplugging and restarting everything to no avail
When I plug in the device I see the following status messages on the device systray, in this order
How can I access chrome inspect on this device? I am using logcat for now but it's far less powerful than chrome dev tools.
This is a known issue.
The answer in the link (changing USB mode from MTP to PTP) did work for me for some time, however others have had less success, and my setup has now regressed to the erratic connection you are seeing.
Personally, I just try to play quick draw and click on the device when it's listed before it disconnects again, which after a bit of practice doesn't take too long, and once you've done that, the actual inspect tools don't have the same erratic connect/disconnect problem so you should be fine until you physically disconnect the device.
This should be resolved in a future version of Chrome.
