High Speed Disable: Disables the capability to attach as either a High/Full-
speed device, and forces attachment as Full-speed only i.e. (no High-Speed
support).
0 = High-/Full-Speed.
1 = Full-Speed-Only (High-Speed disabled!)
Reserved
EOP Disable: Disables EOP generation of EOF1 when in Full-Speed mode.
0 = EOP generation is normal.
1 = EOP generation is disabled.
Over Current Sense: Indicates whether current sensing isganged.
00 = Ganged sensing (all ports together).
01 = Reserved1x = Over current sensing not supported. (must only be used
with Bus-Powered configurations!)
Reserved
Dynamic Power Enable: Controls the ability for the Hub to transition to Bus-
Powered operation if the local power source is removed (can revert back to
Self-Power if local power source is restored).
0 = No Dynamic auto-switching.
1 = Dynamic Auto-switching capable.
Reserved
OverCurrent Timer: Over Current Timer delay.
00 = 0.1ms
01 = 2ms
10 = 4ms
11 = 6ms
Compound Device: Designates if Hub is part of a compound device.
0 = No.
1 = Yes, Hub is part of a compound device.
