They were disabled to make it easier to develop the USB driver but they should be re-enabled now that the USB driver is working. I have added some notes in the code (firmware/usbarmory/usbd/bus.rs) that indicate where cache invalidation should happen before interacting with data structures that are modified by the USB DMA.
