Could I hypothetically pass USB through to v86? Like libusb on the host into v86 on the guest? Or do USB over IP or something?

Chrome supports a USB api that could potentially work for that, https://developer.chrome.com/docs/extensions/reference/usb/

sadly though it's chrome only, not a standard of any kind (no other browsers support it that I know of). ESPHome can use it to program microcontrollers (along with the serial port support).

Classic Google...

That's the old one. https://web.dev/usb/ is the supported one.

What about this: https://wicg.github.io/webusb/

Isn't that because it was explicitly rejected on grounds of security & privacy concerns, rather than 'oh if only others would be up with Google on implementing new features'?

I'm curious -- what's the intended use case for this? This is something we could try to add if gives some cool new functionality.

passing devices through to do libusb stuff with them (like OBD diagnostics on cars)

Oh, so it's not related to PostgreSQL. I'm super interested in new and different uses for WASM. This could open some new doors.

Could you tell me at a high level how you would implement in your mind/opinion passing USB devices through v86/WebUSB/libusb?
