LPC17xx USB Configuration
CONFIG_LPC17_USBDEV_FRAME_INTERRUPT
Handle USB Start-Of-Frame events.
Enable reading SOF from interrupt handler vs. simply reading on demand.
Probably a bad idea... Unless there is some issue with sampling the SOF
from hardware asynchronously.
CONFIG_LPC17_USBDEV_EPFAST_INTERRUPT
Enable high priority interrupts. I have no idea why you might want to
do that
CONFIG_LPC17_USBDEV_NDMADESCRIPTORS
Number of DMA descriptors to allocate in SRAM.
CONFIG_LPC17_USBDEV_DMA
Enable lpc17xx-specific DMA support
