Issue: Computer will not boot past BIOS with large size descriptors.

Having issues with computers hanging on boot when using a descriptor with size of around 1500 bytes.

Device works fine once windows is started, but during initial boot up many motherboards will hang and never boot while device is plugged in.

an example of a descriptor that will cause the system to hang on boot can be found here: http://www.microchip.com/forums/FindPost/378772
