I bought a USB to Ethernet adapter from Apple, and I downloaded a lot things this afternoon. After dinner, both my retina MacBook Pro and the adapter felt very hot, so I unplugged it. Now the MacBook Pro seems to be frozen and I have to hold the power button for several second to force shut it down. And later that day, the adapter refused to work.
Here is the log in my
Oct 25 21:38:08 localhost kernel: AppleUSBEthernet: Ethernet address 20:9a:dd:41:24:89 Oct 25 21:38:10 localhost kernel: AppleUSBEthernet::doReenumerateDevice - Link down, Device 4f764100 Oct 25 21:38:10 localhost kernel: ifnet_detach_final: Waiting for IO references on en2 interface to be released
Any idea? Is my adapter or the kext is broken?
