description "
The USB slave-side endpoints can typically be accessed in two
different ways. There is support for the traditional way of
doing I/O with open/read/write calls, which involves the
use of devtab entries. It is also possible to use a
USB-specific API, defined largely in terms of asynchronous
operations and callbacks (the read/write implementation uses
these lower-level calls). If neither the application nor
any other USB-related packages require the higher-level
read/write calls then it is possible to save some memory
by eliminating the devtab entries.
