WebUSB unable to see device on ChromeOS or MacOS about la104 HOT 5 OPEN

Or maybe it would be possible to support both WebSerial and WebUSB, using the WebUSB polyfill? I don't really know Javascript unfortunately, so I'm probably not the best person to do this.

It should work on Mac, I am using it regularly (not directly the rf analyser, but other projects that use webusb). After starting the app try reconnecting the usb cable (both ends) - the system needs to re enumerate the device. This could be done by software resetting the USB peripheral, but I did not know how to do it on STM32F103. Regarding the webserial - I need to do some research on this, I haven't tried it. Webusb seems more suitable for such applications, because it will directly open the right web application.

Please try reconnecting the usb cable more times... and let me know if it helped (on osx). On osx use "lsusb" utility to check whether the device was properly enumerated:

$ lsusb
Bus 001 Device 001: ID 1209:db42 1209 DS213 Gabuino  Serial: 155412434D57343039FFD50
Bus 000 Device 000: ID 1209:db42 1209 USB 3.1 Bus
Bus 000 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub

Huh, interesting. I started the app before plugging it into my Mac and it definitely didn't work, but when I unplugged it and plugged it back again it did work. So I guess it's just ChromeOS that's not working (and Linux, unless I add custom udev rules).

Also not enumerating on macOS, M1 pro, latest macOS Montery (device stays on "Connect the device to computer" screen).
All firmware built from latest commit (980270baf...)

lsusb output:
Bus 002 Device 001: ID 1209:db42 1209 DS203 Oscilloscope Serial: 257005434E55393136FFD50
(I should add that I have a DS213, not a DS203.)

edit: LA104 webusb stuff fails too.

@wormyrocks, what application are you using? What is shown in chrome's console? Please try 117_gabuino, the most recent version works well on my M1 (bigsur 11.6). If it won't work I will try updating my mac
