WebUSB DFU to program teensy 4.x

[urbanspaceman]

Hi,
I searched the forum but I didn't find anyone interested, do you know if it is possible to implement webUSB DFU on teensy so that it is programmable from Chrome?
This is the reference https://devanlai.github.io/webdfu/dfu-util/

In a commercial or semi-DIY project, can be useful for people who knows nothing about ide/toolchain etc...

Thanks

Currently Teensy only supports USB HID for programming.

thanks paul
is it a software question (which can be implemented over time) or is it a hardware question?
Is there a similar USB HID method for programming via browser?

On Microsoft Windows and Apple MacOS, probably not. The HID driver claims the interface. My understanding (admittedly only from reading, not actually using JavaScript for WebUSB) is it can't use USB interfaces which have been claimed by any drivers.

On Linux, maybe. But you might need to first use libusb to detach the kernel's hidraw driver.

Thanks for the reply Paul, I hope then in a future update

This is the thread to follow for future WebUSB stuff.
