I have an Asus UX305FA notebook that lacks an Ethernet port, so I ordered an Aukey 3 port USB 3.0 hub with Ethernet .Until recently I had the notebook running Linux Mint 18.1 XFCE.  The Ethernet connection would cut out periodically and would re-establish a few seconds later.  I've recently installed Debian Jessie XFCE (running a 4.9 kernel from backports) and the connection is still lost periodically but it is not re-established until a reboot.  I have a keyboard and mouse connected to the USB hub which continue to operate as normal when the Ethernet connection is lost.How can I determine if the disconnections are due to a hardware issue or a configuration problem?  I suspect that it may be a combination of the two...Output of lsusb:Bus 002 Device 007: ID 0bda:8153 Realtek Semiconductor Corp.

I have since tried the following in the hope of finding a solution, but I have not yet been successful:Disabling autosuspend for all USB devices via GRUB.Creation of udev rules to prevent USB power suspension for specific devices.Installation of a newer driver (2.08.0) from the Realtek website.Can anybody suggest something else I could try?EDIT 2: I updated to Debian Stretch and still had the same issue, so I purchased a different Ethernet adaptor.  Fortunately this one works without any problems!
