The Universal Serial Web
summary
WebUSB lets a browser open devices, run a serial-port stack and speak USB protocols; demos show Johnny-Five in the browser controlling an Arduino LED, web adbjs pulling photos and shells from an Android, and an receipt printer checkout demo that scans ISBNs, reads RFID cards and prints receipts — it works. Chrome (and Samsung Internet) hosts WebUSB, HID devices need a keyboard-hack, communication uses control/interrupt/isochronous transfers (and polling), and a past Yubikey bug caused a temporary disable for security.
