Hi, I am trying to send data to a USB device connected to a USB3.0 port over a USB bulk end point using libusb APIs . It is failing failed with error ERROR_IO. The same device and the test program works fine on a USB2.0 port. After enabling the XHCI debug options, I found that I am getting the following errors: "Endpoint xxx not halted, refusing to reset Transfer error on endpoint" I have tested in following kernel : 3.13.7 3.11.0-18 Both gave the same results. The test has been performed on USB 3.0 host controller. Can you please let me know the root cause and possible solutions? Attached is the debug log.
