Lack of WebUSB support has the potential to make me switch from Firefox to something Chromium based :( #Firefox #WebUSB #Why-Mozilla?!-Why?!

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

RTL-SDR With Only A Browser Surely by now you’ve at least heard of RTL-SDR — a software project that let’s cheap TV tuner dongles work as a software-defined radios. A number of projects and tools have spun off the original effort, but in his latest video, [Tech Minds] shows off a particularly unique take. It’s a Web browser-based radio application that uses WebUSB, so it doesn’t require the installation of any application software. You can see the program operating in the video below. There are a few things you should know. First, you need the correct USB drivers for your RTL-SDR. Second, your browser must support WebUSB, of course. Practically, that means you need a Chromium-type browser. You may have to configure your system to allow raw access to the USB port, too. Watching the video, you can see that it works quite well. According to the comments, it will work with a phone, too, which is an interesting idea. The actual Web application is available as open source. It isn’t going to compete with a full-fledged SDR program, but it looked surprisingly complete. These devices have grown from a curiosity to a major part of radio hacking over the years. Firefox users can’t use WebUSB — well, not directly, anyway.

Add WebUSB Support To Firefox With A Special USB Device RP2040-based Pico board acting as U2F dongle with Firefox. (Credit: ArcaneNibble, GitHub) The WebUSB standard is certainly controversial. Many consider it a security risk, and, to date, only Chromium-based browsers support it. But there is a workaround that is, ironically, supposed to increase security. The adjacent Universal 2nd Factor (U2F) standard also adds (limited) USB support to browsers. Sure, this is meant solely to support U2F USB dongles for two-factor authentication purposes, but as [ArcaneNibble] demonstrates using U2F-compatible firmware on a Raspberry Pi RP2040, by hijacking the U2F payload, this API can be used to provide WebUSB-like functionality. The provided demo involves flashing an RP2040 (e.g., Pico board) with the `u2f-hax.u2f` firmware and loading the `index.html` page from localhost or a similar secure context. After this, the buttons on the browser page can be used to toggle an LED on the Pico board on or off. You can also read an input back from the RP2040. This feat is made possible by the opaque nature of the U2F key handle, which means that anything can be put in this blob. This makes it a snap to pass data from the U2F dongle to the host. For the inverse, things get a bit trickier. Here the ECDSA signature is manipulated inside the ASN.1 that is returned to the dongle. Since Firefox performs no signature validation (and Chrome only does a range check), this works. The MCU also auto-confirms user presence by having the key handle start with `oxfeedface`, so the device works without user interaction. However, you do seem to get an annoying popup that immediately goes away. Of course, this only works if you create a special USB device for this purpose. That means your normal USB devices are still secure. While we know it could be a security risk, you can do some cool things with WebUSB. We’ve seen a few projects that use it.

#WebUSB was such a nice idea. Write your hardware's config UI in a web app. Super clean and easy for lots of use cases.

Except in practice it only works well on Chrome and Edge, and then, only on Windows.

After using a #microbit V2.21 with a #Chromebook for months, today it stopped flashing: No compatible devices found. I've tried everything I've found. I've updated the firmware. #webusb inchoatemiscellany.glitch.me#Microbit%20d... Any tips?

I thought I'd play around with the #DEFCON29 Badge, #React and #WebUSB to see what we can do! Should lots of fun, lots of just digging around to see what we can find, 100% completely unscripted!
