[asus tablet] Calibre not displaying Device

[THX1000]

Please let me know if there is somewhere else I should have posted this. I found an older thread on google but it was closed.

Calibre is no longer showing my device. I haven't downloaded the latest version, as I heard there were issues with the latest KFX plugins.

I have done the following:
1)Confirmed that Calibre is not ignoring any devices - these fields are blank
2) Ran the "Debug Device Detection" (see results below)

Am I reading this correctly? Calibre has found and "opened" my asus tablet? If so, any idea why the device is no longer appearing in the Calibre header menu? Calibre is my perferred tool for ebook transfers, so I'd love to figure out how to get it working again.

Thanks!

Yes, according to that your device is being detected and opened successfully. Note that on first open it might take a long time to scan the device. After that, you can right click on the device icon in calibre to configure which folders calibre will scan. When you plugin the device check ifthe jobs spinner in the bottom right is rotating indicating calibre is scanning the device.
