Keith I Myers took the lead in reporting the news, pointing out that Chrome OS can support a range of suitable USB devices in Linux applications, but noting that the function is still in the developer version of Chrome OS, so there are some problems in actual use.

Some users said that Crostini could not start when GPU support was active before the upgrade, and Myers had some help. There is also scrolling in Settings, and the Google Assistant button is no longer applicable to Pixelbooks.
