<p>I don't think we <em>have</em> to wait until someone tried this PR on every OS (I can also only test on Linux) - if it was broken before, it would probably be broken on other operating systems as well.</p>
</blockquote>
<p>I'm not against this, but I think for usbdev peripherals it should be enough to test on one OS. It is very unlikely that only one of the three OS fails/succeeds as that would indicate a USB spec violation at a very low level.</p>
<p>At above USBUS level (CDC ECM, CDC ACM etc.) failures with different OS's become more likely as some require a specific flavor of optional features to correctly detect the function.</p>
