I assume the ASUS ME173X uses internal memory, like the nexus 7.
Since you see the folders on your devices, the issue is about connecting it to your PC. This is outside of KoBoSync, but a known issue.
The problem is that the MTP software on Windows does not update the directories when connecting the device. A few things that may work:
(1) reboot the device itself
(2) if i does not work, you can try to enable debugging mode on your android tablet - it is not needed normally, but sometimes prompt Windows to update the directories.
Hopefully these simple steps will resolve your problem.
It has worked for me in the past (we have deployed hundreds of devices, including Nexus 7 tablets which were the only ones causing this problem)
However,t here is one tablet for which I was never able to see the ODK folders - never understood why - may be someone on the list can help?
The only workaround I found was to install dropsync and use the wifi connection to sync the data. This defeats the purpose of being able to do this completely offline. you may want to try the Bluetooth connection.
Best,
