===Description===

ROCK 3 supports can function. Here we will test it on ROCK 3A.
Here we use Type-A to Type-A USB cable with one port connected to the Type-A socket of ROCK 3A,
and the other port connected to the Type-A socket of the PC.

===Hardware support===

Support hardware platform:
* ROCK 3A x2

=== Operations on ROCK 3A ===
