volatile structure missing element error during compilation of board_driver_usb.c about 9dof_razor_imu

[lunarpulse]

I have investigated a little more and I found out that the USB_DEVICE_EPINTFLAG_Type union contains three fields of structs, bit, vec, and reg. 'TRCPT' and 'STALLRQ' both are member of vec, NOT bit.
the codes was intended to get the status bits stored as a union but the samba_usb.c file did not implement the use of the union struct correctly. I am not sure this was used by arduino zero directly. At least this does not work on atmel and linux arm gcc compiler.

After fixing all the errouneous member indication in the samba_usb.c file, the file compiles but still many errors to correct during the compilation of other files.
