Got this issue after unfortunate upgrade to MacOs Bir Sur :-( These are my conditions: MacOS version 11.2 (20D64) MacBook Pro (15-inch, 2018) USB Hub UGREEN 50852 And this is what solved my problem: Boot into Mac OS Recovery Mode by holding down the ⌘ and R keys during system start. Open Terminal from the "Utilities" menu at the top of the screen and run following commands: sh csrutil disable Disable System Integrity Protection (SIP) sh /usr/sbin/spctl kext-consent add 5RHFAZ9D4P Add manufacturer ID to allow kernel extensions from ASIX sh /usr/sbin/spctl kext-consent list Check that ID was added 3. Reboot 4. Download and install the latest version of the driver from ASIX web-site language https://asix.com.tw/en/product/USBEthernet/Super-SpeedUSBEthernet/AX88179 5. Restart and once again boot into Recovery Mode. Open Terminal and enable SIP language csrutil enable Hope this was helpful 🙃
