They all share the same power source on the Airport that has a limit of 500mA.
If the HDD is a 2.5' (laptop drive) that draws power from nothing else but the USB port it will never work with a USB Hub. Since that port indeed works in this configuration, showing that the port is functional (the hardware is effectively working, so is the driver).Since we see that Mac OS X 10.9 can see the port when the hub is connected through another hub.
How can I force Mac OS X 10.9 to see the ethernet port of my hub (Asix AX88179) ? Sudo kextload -b 88179_178aĪs I get this reply in Terminal : 88179_178a failed to load - (libkern/kext) not found check the system/kernel logs for errors or try kextutil(8).Īnd anyway it would be a terrible hassle to have to do this each and every time.īut when my "USB 3 Hub with Ethernet" is connected through a USB 2 Hub, then the kext is loaded (inexplicably for me) : MBP-computer:~ username$ kextstat -l | grep asixġ37 0 0xffffff7f82879000 0x8000 0x8000 88179-178a (1.0.0) But this is not useful in the long run since this defeats the whole idea of having a SuperSpeed Hub in the first place ! Mike Ohlsen wrote here that when plugging the hub into another USB Hub, and not directly into his Mac, then OS X does detect the ethernet interface and displays the device in the System Information. I already downloaded (and installed !) the latest file from, which is the latest to this day, but System Information does not list the port as being available when I connect the USB 3 Hub directly to the USB 3 port of my MBP.
