So, I can now flash software to this device from my web browser with WebUSB. The code might be the worst Javascript I have written, but it works quite reliably (constraint by how reliable the Micronucleus bootloader is).

Lack of WebUSB support has the potential to make me switch from Firefox to something Chromium based :(

#GrapheneOS installation on a Pixel phone is the easiest Android ROM I've flashed in the past 8 years. I used the WebUSB-based installation method. (Also discovered that my desktop has a USB-C port in the back, lol).

I am not a fan of web browsers turning into operating systems, but this is a good use case for WebUSB. I wonder if we can flash Debian-based operating systems images using this, directly from the official website. Removes the need for desktop apps like Balena Etcher.

#webUSB

@wolf480pl yeah, because the idea is that #drivers should hook in the #USB stack and unless it's a Universal Class Driver should just passthrough to the driver / userspace application for ease of support.

• So userspace applications can either request a specific device (i.e. Gameboy Multiplayer Adapter by @stacksmashing for #WebUSB ) or query all USB devices of a specific type (i.e. #MiniLPA looks for all #Smartcards & #Smartcard-Readers)…

@codinghorror @leon

Yeah, it's using either webusb or webserial which are only supported on Chromium-based browsers :(

Firefox decided to not implement these to APIs citing security concerns :(
#firefox #webusb #webserial

A lot of the development efforts (both creative and destructive) in web browsers in the last decade+ has been going into fostering the “web app” vision of the web, to the detriment of the “web of documents” vision. From the removal of native support for #RSS and #Atom to the introduction of JavaScript APIs like #WebUSB or the “Web Environment Integrity” attempt, nearly all work done on browsers has been in this direction.

I really do wish that @mozilla would allow Firefox to support WebUSB, if not as a core feature, then as an optional extension 😕

#Firefox #WebUSB

Help! My #chromium does not access my #keychron keyboard in #debian oder #webusb

NotAllowedError: Failed to open the device.

#Mozilla (#Firefox) argument against Web #WebUSB/#WebBluetooth is basically "well, you're too dumb to understand the risks and we're to dumb to explain it to you. So let's just leave it."

Ich finde diese Umfrage zu #HTML & Co. inhaltlich interessant, um auf ein paar wenig bekannte oder selten verwendete Techniken zu stoßen.

Für mich erstaunlich, dass #WebUSB erwähnt wird, aber die in den letzten Wochen im Kontext des #Calliopemini eingesetzte #WebSerialAPI nicht.

https://survey.devographics.com/survey/state-of-html/2025

Von daher Finger weg von Zadig und #WebUSB ist wohl aktuell kein Thema für Datenkopplungen zwischen #Calliopemini und Browsern. Selbst wenn das mal klappen sollte, wären die Möglichkeiten auch nicht umfänglicher als die von mir mit der #WebSerialAPI probierten Ansätze zum Empfangen und Senden von Daten (wäre dann auch nur für V3 einsetzbar, meine Beispiele laufen mit V1/V2/V3).

Als letzte Option noch die Verbindung eines #Calliopemini 3 über #WebUSB probiert. Formale Kopplung ok:

const device = await navigator.usb.requestDevice({ filters: [{ vendorId: 0x0D28, productId: 0x0204 }] });

Beim folgenden await device.open(); kommt jedoch direkt access denied. Alle nachlesbaren Ideen halfen nicht, u. a. mit einem Tool namens »Zadig« WinUSB-Treiber nachzuladen. Fehler bleiben gleich, aber man zerschießt sich damit auch die bisherigen funktionierenden seriellen Zugriffe.

I kinda think #Firefox should just do #WebUSB at this point

Sneak preview:

#websdr #rtlsdr #webusb #html5

because @mozilla thinks someone might be able to do harmful things with #WebUSB they do not want to add WebUSB to #firefox.

I wonder if #mozilla has ever heard about the possibilities of JavaScript. 🙄

Это под силу даже веб-разработчику! Размышляю, как создать драйверы на JavaScript с API WebUSB

Привет! Я Игорь Кечайкин, руководитель группы разработки во Frontend-команде Flocktory. Недавно, решая задачу, связанную с API WebUSB для Fingerprint-атрибуции пользователя, задался совершенно не связанным теоретическим вопросом: а как создать с этим API драйверы на JavaScript? Чтобы разобраться, изучил спецификацию API WebUSB, а теперь принёс на Хабр выжимку самых важных элементов. В статье я расскажу о принципах работы решения и том, что с ним делать веб-разработчику, который хочет напрямую реализовать на сайт функцию, например, 3D-принтинга с пользовательских девайсов. А также вы узнаете, насколько это безопасно — для сайта, внедряющего API, и для девайсов юзера. Если интересно, как расширить возможности своих сайтов и избавиться от головной боли с адаптацией под всевозможные устройства, заходите в статью.

Another day, another 🥪 of #tech #hysteria wrapped in a desperate attempt to make #Firefox relevant again. Instead of waiting for #WebUSB, let's just build an entire Rube Goldberg machine to reinvent the wheel! As if GitHub isn't already bursting with enough "ingenious" hacks nobody asked for. 🙄
