+
+       Drivers -> USB Host Driver Support

+         CONFIG_SCHED_LPNTHREADS=1
+         CONFIG_SCHED_LPWORKSTACKSIZE=1024
+
+       NOTES:
+
+       1. It is necessary to perform work on the low-priority work queue
+          (vs. the high priority work queue) because deferred hub-related
+          work requires some delays and waiting that is not appropriate on
+          the high priority work queue.
+
+       2. Stack usage make increase when USB hub support is enabled because
+          the nesting depth of certain USB host class logic can increase.
