Does USB_CDC_ACM host support hot-plugging?

Open andy817501 opened this issue 9 months ago • 7 comments

I did not find any information about hot plugging in the document. During my testing, I found that after the host communicates with the device, disconnecting the device will prevent it from connecting properly

At a minimum, we could improve the documentation around this, @andy817501. I will discuss this with the team.

Can you share additional details about your application and the hardware it runs on, @andy817501?

In particular, we are interested in the USB controller you are using and the type of device you are trying to plug. Many behaviours are hardware-dependent, and we need more context to provide appropriate guidance.

Thank you in advance.
