libu***_dev_mem_alloc（）API是否用于USB DMA传输的任何地方？

CYUSB的来源有LiPulb API。但它们似乎没有使用LuBubxDeViMeMyOLLC（）API。
例如，批量数据传输是使用CysBuBulkJuffic API完成的，内部调用LiBubSulkkType（）API。这调用了LIUBBUBALLOLJORACTION API，它为传输分配了一些预定义的内存。
供参考：
你可以在这里下载CyUSB Linux主机源码：

此外，LYBUB开放源代码可以在这里下载：

     以下为原文
  The source of cyu*** has libu*** APIs. But they do not seem to use the libu***_dev_mem_alloc () API.
 
For example the bulk data transfer is done using the cyu***_bulk_transfer API which internally calls libu***_bulk_transfer () API. This calls the libu***_alloc_transfer API which allocates some predefined memory for the transfer to take place.
 
For reference:
You can download the cyu*** linux host source here:

Also, the libu*** open source can be donwloaded here:
