Is there an Apple USB Ethernet driver for Windows?

I did a little more hunting online and found this link to a blog that said they'd found the driver for the chipset in the adapter, and convinced it to work. I followed a variant on their instructions, and it worked for me too. Here are the steps I used:

  1. Plug in the adapter while the computer is running.
  2. Check Device Manager (you can get there by right-clicking Start). You should see a listed Apple device with a little yellow exclamation mark next to it, saying Windows can't load the driver.
  3. Go to the website listed in the blog post and find the driver for your OS. I used this one for 64-bit Windows 10. Note that this is the actual driver download, not a Setup program.
  4. Download the .ZIP file. If you use a browser that adds the "mark of the web" (IE or Edge for sure, maybe others), right-click the downloaded ZIP, go to Properties, click Unblock (either a button or checkbox), and hit OK.
  5. Unpack the ZIP archive. You should see a folder containing four files: a .SYS file (the driver), a .CAT file (the WHQL signature), a .INF file (the driver information), and a Readme.txt. Don't do anything with these files directly, but remember where they are.
  6. Go back to Device Manager, right-click the device entry that needs the driver, and choose Update Driver Software....
  7. Choose Browse my computer for driver software.
  8. Choose Let me pick from a list of device drivers on my computer.
  9. If there's a Have Disk... button in the lower right, click it. Otherwise, click the top entry in the list (should be something like "All devices") and hit OK, then click Have Disk... on the next screen.
  10. In the box labeled "Copy manufacturer's files from:", type in or browse to the location where you unpacked the .ZIP file, then hit OK.
  11. Choose the option ASIX AX88772A USB2.0 to Fast Ethernet Adapter (on my system, it is the second option listed). Hit Next.
  12. You will get an "Update Driver Warning" or similar saying that Windows can't verify that the driver will work with your hardware, which may cause problems. Click "Yes" anyhow, for this and any other prompts to confirm that you want to install the driver.
  13. You should now have a working Ethernet adapter! In Device Manager, it will be listed as a "ASIX AX88772A USB2.0 to Fast Ethernet Adapter" under the "Network adapters" category, and there should be no exclamation marks or anything like that.

There you go! You can connect to a wired network, and it should work fine. The original instructions were for Windows 8 x64, and I can verify that it works on Win10 x64; I haven't tested it on other versions but the same steps should work and the download site lists drivers for tons of operating systems.


If you prefer to download the driver directly from Apple's site:

  1. Download the latest version of "Boot Camp Support Software" from Apple.com: http://support.apple.com/downloads/#macoscomponents
  2. Open the ZIP file and go into the BootCamp\Drivers\Asix driver
  3. Run the AsixSetup64.exe driver installer

From Microsoft

search the windows update catalog Windows update catalog for ax88772

and get the driver from them.

Download the cab, extract it and install it using the device manager. It doesn't matter which "name" you select - you get an warning that the driver will not fit - but they all work.

From Apple

Download the update catalog file using the official links:

https://pikeralpha.wordpress.com/2017/06/06/catalogurl-for-macos-10-13-high-sierra/

eg. https://swscan.apple.com/content/catalogs/others/index-10.13seed-10.13-10.12-10.11-10.10-10.9-mountainlion-lion-snowleopard-leopard.merged-1.sucatalog.gz

Extract the xml file and open it in notepad++

Search for "BootCampESD.pkg" (CTRL+F) and you will find many of them.

In the search result window double click the latest one and download the full url to the BootCampESD.pkg

As of writing the newest one was: http://swcdn.apple.com/content/downloads/41/17/091-14331/br9prfd71k86fkwgx421ept2s931s0bv2p/BootCampESD.pkg

Extract the *.pkg using 7-Zip: BootCampESD.pkg\Payload~.\Library\Application Support\BootCamp\WindowsSupport.dmg

Extract the *.dmg also with 7-zip: WindowsSupport.dmg\BootCamp\Drivers\Asix\AsixSetup64.exe

Extract the *.exe (rarsfx) again with 7-zip and you get the plain driver:
