STM32F3 USB Overflow

I'm currently using USB for communication between a server and my ST32F373C8.  I'm sending a lot of data back and forth between the two and I believe that I am overflowing the USB PMA before I am able to copy it over to the user space.  I was wondering if anyone knew if there is some overflow protection so that the data is held until there is space in the PMA for my endpoint or if the data is just lost.  Also, I was wondering if there is a way to increase the buffer size for my endpoint so that I don't overflow and lose data.  I read something about double-buffering, but I'm not sure if that's what I want to do or if that is used for something else.

Thanks in advanced for any help!
