ECUSB_Device_Detach
The USB_Device_Detach detaches the USB device, i.e. it de-activates the USB Device Port which allows the host to communicate with it.
ECUSB_ErrorCode ECUSB_Device_Detach(
struct ECUSB_Device *pDevice
);
struct ECUSB_Device *pDevice
);
Parameters
pDevice
A pointer to a struct ECUSB_Device previously initialized by ECUSB_Device_Init.
Return value
Returns one of the ECUSB error codes (ECUSB_SUCCESS on success)
Remarks
If you have a self-powered device and a configurable pull-up, you can call ECUSB_Device_Detach when you want the host to disconnect from your device.
If you do not have a configurable pull-up it doesn't make sense to detach since the host most likely will report your device as broken.
Example Code
err = ECUSB_Device_Detach(&myUsbDevice.m_device);
if(err != ECUSB_SUCCESS)
halt("ECUSB_Device_Detach failed", err);
