usb 3.0 gigabit ethernet adapter will not connect

[dono42]

I am migrating from a Mac Mini 2012 to a Mac Mini 2014. The usb connections i have are a Wifi hotspot in tethered mode, Anker gigabit (Realtek 8153), keyboard/mouse and a connection to a UPS. Every connection worked on the 2012. The issue I have on the 2014 is the Anker gigabit will not connect a boot. If I remove and reconnect the Anker gigabit it starts. I did load the Realtek driver from Anker, I verified the driver is loaded with kextstat. Also can someone explain the usb architecture? Early Mac Mini block diagrams I have seen looks like all of the ports are on one buss of the usb chip. I thought maybe power but the system report shows 900mA available, 256mA required for the Anker

Decided to uninstall the realtek driver com.realtek.driver.AppleRTL815XEthernet and reboot without 3rd party driver. It works, connects at boot, found that apple has a driver for realtek com.apple.driver.usb.realtek8153patcher. Maybe there is an issue with the realtek driver and the different host controllers. There is a newer version of driver available from realtek, if I have issues I'll try it.

Hey, just wanted to say this fixed my issue with an Aukey HUB that contains the same Realtek 8153 chip. It would never work at boot, needed to switch it off and on again.
Uninstalled the driver with the script in Realtek's package and rebooted. Problem solved.
