HUB Descriptor
Number of ports supported
b1, b0: Logical Power Switching Mode
00: Ganged power switching (all ports’ power at once)
01: Individual port power switching (Default in TetraHub)
b2: Identifies a Compound Device,
0: Hub is not part of a compound device (Default in TetraHub),
1: Hub is part of a compound device.
b4, b3: Over-current Protection Mode
00: Global Overcurrent Protection. The hub reports overcurrent as a
summation of all ports current draw, without a breakdown of individual port
overcurrent status.
01: Individual Port Overcurrent Protection. The hub reports overcurrent on
a per-port basis. Each port has an over-current status (Default in TetraHub).
1X: No Overcurrent Protection. This option is allowed only for bus-powered
hubs that do not implement overcurrent protection.
b6, b5: TT Think Time
00: TT requires at most 8 FS bit times of inter transaction gap on a
full-/low-speed downstream bus (Default in TetraHub).
01: TT requires at most 16 FS bit times.
10: TT requires at most 24 FS bit times.
11: TT requires at most 32 FS bit times.
b7: Port Indicators Supported,
0: Port Indicators are not supported on its downstream facing ports and
the PORT_INDICATOR request has no effect.
1: Port Indicators are supported on its downstream facing ports and the
PORT_INDICATOR request controls the indicators. See Section 4 and 9
(Default in TetraHub).
b15, ..b8: Reserved
Time from when the port is powered to when the power is good on that port
Maximum current requirement for the Hub Controller
Indicates if the port has a removable device attached
Required for compatibility with software written for 1.0 compliant devices
