Zephyr - The USB driver issue of WebUSB example

[Hsu]

Hi Sir,

We plan to test the WebUSB example under the below path: 

/ncs/1.8.0/zephyr/samples/subsys/usb/webusb

HW: nRF52840-DK

When we compile, program and connect to the Win 10, we got the win10 needs to install the usb driver.
As check the /ncs/1.8.0/ we cannot find the usb driver file there.

We tried to download the usb driver from the below link, but it didn't work.
https://www.driverscape.com/manufacturers/zephyr/usb

Could you share where we can download the Zephyr USB driver?



Thank you.

Hi,

The WebUSB driver should be supported in your system since you have a Windows > 8.1

You could take a look at the WebUSB Troubleshooting as a start.

As for the usb_cdc_acm, there are two drivers in the nRF5 SDK but I would suggest you to check the Troubleshooting as you are missing the WebUSB driver.

Regards,

Priyanka

Hi Priyanka,

According to the WebUSB Troubleshooting, I cannot find the  "mbed Composited Device" under the Universal Serial Bus controllers.

When plug-in the device, only "Generic USB Hub" added under the Universal Serial Bus controllers.

I also tried to install from nRF5 SDK "\SDK_17.1.0\examples\usb_drivers", but helpless.

Should we re-build the USB driver for WebUSB example?

Thank you.

Hi Han,

I conveyed the issue internally and there is no need to have a WebUSB driver as USB device interfaces can be assembled and accessed from web pages via web browsers.

You could take a look at this statement. Also, there are the Microsoft OS Compatibility Descriptors, so it should work without the INF file.
