Let's pick a legacy app, say... Office 2003. If I need to save new data, it pops up and asks me where do I want to save it? I'm okay with his because I know where I am telling the system to save the data.
And if Office 2003 is written in JavaScript and run in a browser, you'd stop being okay with this same chain of events?
Absolutely . Because I get a popup about where the data is going. (See my latest comment)
Just like how it is described in the WebUSB papers?

If you knew about this site, that could have avoided three whole pages of back and forth, lol. Thank you.

Here is how it works...
- Legacy Apps run on the OS and have USB access, period. They are not gated from access and can do anything that they want.
- Modern Apps using WebUSB need to pop up to ask permission for access.
All apps need peripheral access to work fully. Really, the two should be treated equally. But given deficiencies in legacy apps around security, WebUSB addresses that.

I didn't, but it was obvious that it had to exist. You have to admit, thinking that all web sites suddenly had peripheral access without any security, totally different than anything that web protocols have ever done, was not even remotely in the realm of reason to assume, even if some paper made it sound that way. I posted that the moment that I found it. But it is just what you had to know going in.
Also, much of this discussion is other things... like explaining why apps would use USB, how USB has no function if apps can't use it and how legacy apps have not had the imagined security in the past.

Example to test USB access... add a USB sound card, there is no pop up or notification but "all" apps with sound get instant access to it. Same thing with a USB hard drive. No pop ups, but apps have access without the user knowing. In fact, it is common for apps to use peripherals and unless that peripheral does something to alert the end user, the end user would never know that they were being accessed. You can print, look at web cams, play music, listen to microphones, access filesystems, all without telling the user anything at all, ever. Good apps rarely do this, but even good ones do sometimes because people expect these things to work.
None of my USB devices ... keyboard, mouse, headphones, printer, webcam, microphone... have any user interaction for use. Not a one of them today.

In my example of our application from 1999... this is how we were able to make it work. We built our own WebUSB equivalent and because we did it using VB6 originally (and later C#, we aren't proud of the VB stuff) we were able to access the USB and RS232 without the users knowing. There is no user interaction at all for our app that has been doing this since NT4 and has worked the same on every Windows version since. With WebUSB, we can simplify the process a lot, but it will get complicated in that for the first time ever, there will be USB security to deal with for the end users.

And you think this is different? Why?
With any application that is going to access my device, I get some kind of indicator (File Save Dialog, or a progress window, you get the idea). I'm perfectly fine with this as long as there is such an indicator (I see no mention of any type of indicator for this).
No, you are totallywrong here . Apps access your devices al, the time without telling you a damned thing.

All of these things work through system APIs, the main one I'm personally concerned about (but apparently the webUSB will prompt) is storage, and also the camera/microphone. The applications probably in general don't know they are working with USB, they only know they are working with a sound card. The system handles the interface to USB, but the sound APIs handle the access for the application. Obvious exclusions would be something like iTunes. It knows about the hardware directly. The camera software would be the same.

As long as this works similar to how access to things on the iPhone work, I'm OK with this.
