This option provides a dedicated work queue that is used for
|
|
all offloaded operations initiated by the USB subsystem.
|
|
This prevents deadlock situations where tasks on the system
|
|
workqueue inadvertently initiate operations that block, such
|
|
as UART transmission on CDC-ACM, preventing the system work
|
|
queue from making progress on the USB tasks that would
|
|
release the task.
|
|
|
|
Without this the system work queue is used for all USB
|
|
offloaded transfers.

By default, USB work queue priority is the lowest cooperative
|
|
priority. This means that any work handler, once started, won't
|
|
be preempted by any other thread until finished.
