Does USBX support multiple device type switching? #40

Closed arilink-tech closed 2 years ago

arilink-tech commented 3 years ago

The processor used in my project is STM32F105RBT6. I transplanted ThreadX and USBX for development. I want to know if USBX supports multiple device type switching. For example, USB is a normal USB device when it is working normally. When firmware update is required, enter USB DFU mode?

Host recognized device is actually from what device reported (descriptors), if your application start different USB framework on different triggers, host will see different devices. So yes, USBX supports multiple device type switching.

I know this situation, I mean, for example, the currently running USB class is CDC. After receiving the command, can it be converted to HID through some operations without resetting the system?

You can try following flow: If hardware support, issue detach. Disconnect, unregister classes, uninitialize device stack, then initialize device stack with another device framework, register classes again ... Then attach ...

@xiaocq2001 how can i send a multiple audio isochrone packet in host app ?

xiaocq2001 commented 2 years ago

@BlueShark7 Not sure what you mean for multiple audio isochrones packet, do you mean the usage of host audio class APIs?
