No device node in Media Tree if lock screen present [#11587]

[Barry4679]

If I connect my Nexus 7 tablet to PC via USB while sleeping it is awakened, and is recognised by Windows (ie. is accessible within the Explorer within Computer), and it is recognised by Dropbox synch, but it is not recognised by MMW (ie. I get no "Nexus" node within the Media Tree.

The same thing happens if the tablet is awake when I plug via USB, but screen lock is active.

I have to awaken tablet, and provide the Android screen lock credentials *before* plugging in the USB, in order to get the device node.

Apparently this is not the case with sone other tablets according to wutzin in another thread.

I just tested USB sync with two different Android devices - it works fine even if the screen is locked when plugging in the device. If your device behaves differently, then you have a buggy Android kernel who can't properly handle USB connections. This has nothing to do with MM and doesn't belong anywhere in the MM documentation.

I don't see how the Nexus products can be seen as having a buggy kernel given that they are produced for Google. I have had both the the original version of the Nexus 7, and the 2013 version with KitKat. Both have displayed this behaviour.

I've tested with numerous devices, and the requirement to enter the lock screen credentials in order to be able to view the device's contents occurs on all of my test devices. Note: if the lock screen is set up without any security (e.g. just a swipe), then access to the device doesn't require bypassing the lock screen in advance--it's only if a secure pin/pattern/etc. has been enabled.

I think the problem is:

If an Android device is locked when it is connected and then unlocked later it still doesn't show in MMW. The ideal situation would be for MMW to recognise the device once the storage becomes available.

And although Windows Explorer shows the device here, it can't do anything with the device (without any feedback).

Yes, thanks, that's it.

It can be initially confusing as the Device node can appear to go awol, and the behaviour is different to Explorer, and is therefore unexpected. See this thread:
