The only reason they might is that this list has become a list not just of bus-dma conformance, but locking as well (i.e. a general driver feature/requirement list), so while the DMA-related entries should probably be N/A for the USB devices, the locking fields are still relevant. We could move the list of drivers to a separate driver-features list page if you would prefer. -- John Baldwin
