【i.mx.rt1061】 the USB device can not detect disconnection from a host

[bobhi009]

Hi:

        I try to get a notification when the USB decice disconnected from a host.

1. I modified the value of the macro definition USB_DEVICE_CONFIG_DETACH_ENABLE 

/*! @brief Whether the device detached feature is enabled or not. */
#define USB_DEVICE_CONFIG_DETACH_ENABLE (1U)

2. Add  Event handler In callback function 

But cannot detect the connection status.

when I modify the ehci driver  like shown as below , I can detect the device plug into a host , and can't detect unplug from the host yet. 

So how to get a notification when the USB decice disconnected from a host.

Hi @bobhi009 ,

Did you menage to solve this issue??

@jingpan 

The thing is that USB_DeviceEhciIsrFunction(...) function is not even triggered when USB is detached...

Hi @bobhi009 ,

I follow you step on my RT1060 EVK. It works well. Attach and Detach information is printed on UART.  I test on the USB CDC demo.
