But works okay on Linux? Works okay with an older ZJS build?

@grgustaf Yes its ZJS related, it got introduced with @zolkis new webusb PR. There is some needed Windows key descriptor in order for chrome to recognize it. If you look at src/ashell/term-webusb.c (before it got deleted by the webusb PR) it contains ms_os_20_descriptor_set, which does that work. I tried adding that to src/ashell/webusb_driver.c but it still didn't work, so its a little more complex than that I guess. Anyway, yes it works on any earlier build before the webusb change, and yes it still works on Linux.
