We discussed this on IRC.
Linux reports (DMI) this is an: ASUSTeK COMPUTER INC. TP202NAS/TP202NAS, BIOS TP202NAS.209 07/19/2018
This systesm' only internal storage which is not detected here (other than the error messages quoted above) is a SanDisk DF4064 eMMC.
I recommend testing also with an Ubuntu 18.04.2 live system, running "apport-collect 1818407" from it, and posting a full dmesg (if apport does not do that already).
