µTasker general / uTasker MSD Serial Loader is not working with custom board

Hi everyone, I'm having some troubles while trying to use the MSD mode of the uTasker Serial loader project for kinetis. I have already test the bootloader with a TWR-K53 using the TWR-ELEV headers (I connected the USB cables to the headers directly) and everything worked fine. Nevertheless, when I flash the same .elf file to my custom board, my PC doesn't recognize the USB conection ("usb device not recognized").
I think it may be a hardware problem. I have attached the schematic of my custom board USB conection.
