I want to make sure I understand the solution: We will create a new IOCTL, i.e., USBDEVFS_SUBMITURB_SS. This IOCTL will pass new URB structure, usbdevfs_urb_ss, which will hold the "legacy" URB and in addition the stream_id. libusb will be able to use the new ABI whenever SuperSpeed streams are required. Is this correct? Thanks, Amit Blay, --- Sent by an consultant of the Qualcomm Innovation Center, Inc.
