My new OS X El Capitan cannot detect USB to ethernet Adapter ( JP208B ) and cannot use ethernet internet access any more after upgrading to El Capitan
USB to ethernet adapter cannot be detected and used after upgrading to Mac OS X El Capitan from Yosemite. My ethernet adapter is JP208B and is no longer detected with My MacBook Air ( Mid 2013 ). At first , I am doubtful my ethernet adapter is malfunctioned so I bought new ethernet adapter ( JP1081B ). But both adapters cannot be detected with my MacBook Air . Please help me with the question of " Is there anyone facing this problem ? " I am strongly requested to solve and give advice to me for solving this issue . Thanks !
MacBook Air, OS X El Capitan (10.11)
