<p>Please verify that you are running the correct drivers for the USB to serial adapter that you’re using. Information and download links for the drivers used by the most common devices can be found <a href="https://www.miklor.com/COM/UV_Drivers.php">here</a>.</p>
<p>While it is preferred to use devices that use authorized/original versions of the various USB to serial chipsets, it is possible to use some cloned devices with older drivers. When doing this, you may also need to force Windows to use an older version of a driver instead of automatically updating the driver on reboot. See <a href="https://wethegeek.com/how-to-disable-automatic-driver-updates-in-windows-10/">here</a> for instructions on doing so in Windows 10. For Windows 8:</p>
<ol type="1">
<li>Search for “Change device” in the Windows 8 Start menu.</li>
<li>Click on where it says “Change device installation settings”.</li>
<li>Select the “No, let me choose what to do” option.</li>
<li>Check the “automatically get the device app” option, then click Save changes to save the settings you just chose.</li>

If you are experiencing issues with 2020 mode on these Macs, please let the development team know so that further investigation can be done.</p> <p>Preliminary testing on ARM Macs has shown that NEON optimizations in LPCNet are sufficient to allow 2020 to be whitelisted on those machines.
