USB Hub Support
----------------
USB hub support can be included by adding the following changes to the configuration (in addition to those listed above):
Drivers -> USB Host Driver Support
CONFIG_USBHOST_HUB=y : Enable the hub class
CONFIG_USBHOST_ASYNCH=y : Asynchonous I/O supported needed for hubs
System Type -> USB High Speed Host driver options
CONFIG_SAMA5_OHCI_NEDS=12 : You will probably want more pipes
CONFIG_SAMA5_OHCI_NTDS=18
CONFIG_SAMA5_OHCI_TDBUFFERS=12
CONFIG_SAMA5_OHCI_TDBUFSIZE=128
Board Selection ->
CONFIG_SAMA5D4EK_USBHOST_STACKSIZE=2048 (bigger than it needs to be)
RTOS Features -> Work Queue Support
CONFIG_SCHED_LPWORK=y : Low priority queue support is needed
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.
