I use the virtual com to receive data from PC, and it works normal.

After finish receive data I want to disconnect and close virtual com.

I try call USB_Class_CDC_Deinit(g_app_handle) to finish the receive job.

Then I got a task error "mqx_not_resource_owner" on doing "_usb_device_deinit".


my flow is -

1. Init virtual com.

2. Receive data from PC.

3. call USB_Class_CDC_Deinit to disconnect with PC.


I try call USB_Class_CDC_Deinit on callback function.

It works normal.

but this not meet my requirement.

Is there something wrong with me?
