I am creating a cocoa application for updating a usb hid device. I have everything working using iohid libraries with one exception. I have a need to read out a large amount of collected data from an internal processor. I have been using IOHIDDeviceRegisterInputReportCallback paired with IOHIDDeviceSetReport to perform my writes and reads. My reads have been fine in small scale (less than one packet of 44 bytes). When I am trying t read multiple packets, the first packet is correct with a lot of junk afterwards. I also have tried IOHIDDeviceSetReport followed by IOHIDDeviceGetReport for a synchronous communication with no success. Any suggestion would be helpful
