MSP430F5503: webUSB support?

Part Number: MSP430F5503

Hi,

I've made a USB reader declared as HID and I'm looking for implementing the support of webUSB API (https://wicg.github.io/webusb/#introduction) because our web application accesses the reader.

WebUSB use Binary Object Store (BOS) to declare new parameters, and it seems to be only supported by USB2.1 (documentation from Arduino https://github.com/webusb/arduino/)

- Could someone explain me what is USB2.1? I didn't find any good explanation and the http://www.usb.org does not have any section about it. I only find that is seems related with Link Power Management (LPM)

- Could the MSP430 USB library be modified to support webUSB? Or some hardware is required to fulfill the "USB2.1"

As shown on the Arduino page, "USB 2.1" is just a different version number.

However, you still have to implement the required descriptors. I am not aware of any library implementing the BOS descriptors, but if you have experience with the USB specification, you should be able to add them.

Hello Argail,

The MSP430 USB Stack does not currently support the BOS descriptor. It could be theoretically added by an end user. MSP430 has no current plant o add BOS support.

Ok, I'm fine with this answer, thank you.

I'll try to understand how to modify the stack... :)
