I'm afraid your browser has been talking to the robots again a gentle intro to WebUSB

on YouTube ↗32m

" summary

WebUSB lets a webpage open and claim USB devices so the browser talks directly to hardware; it already works in Chrome (including Chrome for Android) and is implemented by calling navigator.usb and selecting a device. Demos use an Adafruit Feather 32u4 with an OLED driven via a WebUSB-to-serial shim, johnny-five, PNG-to-LCD and heavy webpack bundling to draw images, and an AVRISP mkII to flash an Arduino by writing 128-byte pages (page writes show progress but boot fails due to address bugs). The claim is practical: real devices are detected, descriptors are readable, and end-to-end demos mostly work with duct-tape fixes.
