USBH Special Function Keys Input

(Please take a look at the attachment)

I am trying to use a keyboard with special keys ('Open Browser' and 'Open Mailbox' etc.) with the STM32F4 Discovery USB host library. For all other keys I am getting 8 byte buffers as expected but for these special keys I am getting 5 byte buffers.

When these special keys are pressed the program freezes and I have to reset the keyboard for it to work again. I need to filter out these 5 byte buffers and somehow ignore them when these are pressed. How can I do that in the stm discovery USB host firmware
