Port Disable (Self) Register (PDS)
Disables 1 or more ports.
0 = Port is available
1 = Port is disabled
During Self-Powered operation, this selects the ports which will be permanently
disabled, and are not available to be enabled or enumerated by a host controller. The
ports can be disabled in any order, the internal logic will automatically report the
correct number of enabled ports to the USB host, and will reorder the active ports in
order to ensure proper function.
Bit 7 = RESERVED
Bit 6 = RESERVED
Bit 5 = RESERVED
Bit 4 = RESERVED
Bit 3 = 1; Port 3 disabled
Bit 2 = 1; Port 2 disabled
Bit 1 = 1; Port 1 disabled
Bit 0 is RESERVED, always = 0b
Port Disable (Bus) Register (PDB)
Disables 1 or more ports.
0 = Port is available
1 = Port is disabled
During Bus-Powered operation, this selects the ports which will be permanently
disabled, and are not available to be enabled or enumerated by a host controller. The
ports can be disabled in any order, the internal logic will automatically report the
correct number of enabled ports to the USB host, and will reorder the active ports in
order to ensure proper function.

Bit 6 = RESERVED
Bit 5 = RESERVED
Bit 4 = RESERVED
Bit 3 = 1; Port 3 disabled
Bit 2 = 1; Port 2 disabled
Bit 1 = 1; Port 1 disabled
Bit 0 is RESERVED, always = 0b
Max Power (Self) Register (MAXPS)
Value in 2mA increments that the Hub consumes from an upstream port (VBUS) when
operating as a self-powered hub. This value includes the hub silicon along with the
combined power consumption (from VBUS) of all associated circuitry on the board.
This value also includes the power consumption of a permanently attached peripheral
if the hub is configured as a compound device, and the embedded peripheral reports
0mA in its descriptors.
Note:
Max Power (Bus) Register (MAXPB)
Value in 2mA increments that the Hub consumes from an upstream port (VBUS) when
operating as a bus-powered hub. This value includes the hub silicon along with the
combined power consumption (from VBUS) of all associated circuitry on the board.
This value also includes the power consumption of a permanently attached peripheral
if the hub is configured as a compound device, and the embedded peripheral reports
0mA in its descriptors.
The USB2.0 Specification does not permit this value to exceed 100mA.
