Hello,
we are very excited by WebUSB and we started to experiment with it, and it seems it is working pretty great.
However, I am not sure about the estimated time of arrival for all websites. When can we expect webusb to be working everywhere?
Ideally, it should be before Chrome Apps are turned off - we use that today for USB communication (the USB communication happens in the background app, which sends messages back to the webpage through messaging). Right now, you are turning Chrome Apps API off without any fully working equivalent for USB.
