Cancelling USB Transfers

Question asked by Chuck Horkin on Feb 24, 2014

I have added a timeout in my code to make sure that my data being sent out on the BULK_IN pipe finishes in a certain time.  If it doesn't, I want to abort the transfer (aka flush it from the pipe).  I've tried using the USB_DCI_Cancel_Transfer/_usb_device_cancel_transfer() function, but that ooesn't seem to work properly.  I would expect that once I call that function, the g_winusb_endpoint_data.ep[index].bin_consumer and g_winusb_endpoint_data.ep[index].bin_producer would once again be equal.  I don't think that is the case.

 

What is the proper way to flush my pipe from my device?  Do I need to reset the endpoint somehow?


Thanks.
