Description
PowerOnToPowerGoodTime: This byte specifies the duration
HCD has to wait before accessing a powered-on port of the Root
Hub. The unit of time is 2 ms. The duration is calculated as
POTPGT
reserved
NoOverCurrentProtection: This bit describes how the
overcurrent status for the Root Hub ports are reported. When this
bit is cleared, the OverCurrentProtectionMode field specifies
global or per-port reporting.
0 — overcurrent status is reported collectively for all downstream
ports
1 — no overcurrent reporting supported
OverCurrentProtectionMode: This bit describes how the
overcurrent status for the Root Hub ports is reported. At reset, this
field reflects the same mode as PowerSwitchingMode. This field is
valid only if the NoOverCurrentProtection field is cleared.
0 — overcurrent status is reported collectively for all downstream
ports
1 — overcurrent status is reported on a per-port basis. On
power-up, clear this bit and then set it to logic 1.
DeviceType: This bit specifies that the Root Hub is not a
compound device—it is not permitted. This field should always
read/write 0.
