USB3-RJ45 adapter without USB ports doesn't seem to work with Android Galaxy Tab S4 with USB-C to USB3-A adapter. Red power light is on when but that's it. This adapter works with a 10 year old laptop and PF Sense says 1GB will obviously never reach that on USB 2. Now it seems to work on Galaxy Tab S4 and S9. An update to Android 9 was recently released that may have made a difference or included drivers.
