usb hid reads



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
