41    The A-device (with micro A plug inserted) should enumerate B-device.
45    On B-device::
49    B-device should take host role and enumerate A-device.
51 4) A-device switch back to host.
53    On B-device::
57    or, by introducing HNP polling, B-Host can know when A-peripheral wishes to
58    be in the host role, so this role switch also can be triggered in
59    A-peripheral side by answering the polling from B-Host. This can be done on
60    A-device::
64    A-device should switch back to host and enumerate B-device.
66 5) Remove B-device (unplug micro B plug) and insert again in 10 seconds;
67    A-device should enumerate B-device again.
69 6) Remove B-device (unplug micro B plug) and insert again after 10 seconds;
70    A-device should NOT enumerate B-device.

74    On A-device::
79    if B-device wants to use bus:
81    On B-device::
85 7) A-device power down the bus.
87    On A-device::
91    A-device should disconnect with B-device and power down the bus.
93 8) B-device does data pulse for SRP.
95    On B-device::
99    A-device should resume usb bus and enumerate B-device.

106 2. How to enable USB as system wakeup source
107 --------------------------------------------
108 Below is the example for how to enable USB as system wakeup source
111 2.1 Enable core's wakeup::
113 	echo enabled > /sys/bus/platform/devices/ci_hdrc.0/power/wakeup
115 2.2 Enable glue layer's wakeup::
117 	echo enabled > /sys/bus/platform/devices/2184000.usb/power/wakeup
119 2.3 Enable PHY's wakeup (optional)::
121 	echo enabled > /sys/bus/platform/devices/20c9000.usbphy/power/wakeup
123 2.4 Enable roothub's wakeup::
125 	echo enabled > /sys/bus/usb/devices/usb1/power/wakeup
127 2.5 Enable related device's wakeup::
129 	echo enabled > /sys/bus/usb/devices/1-1/power/wakeup
131 If the system has only one usb port, and you want usb wakeup at this port, you
132 can use the below script to enable usb wakeup::
134 	for i in $(find /sys -name wakeup | grep usb);do echo enabled > $i;done;
