Bit 4: NoPortIndicators: Turns off the port indicators and
does not report them as present in the HubDescriptor,
wHubCharacteristics b7 field. Default set to 0.
Bit 3: Reserved: This bit is reserved and should not be set
to 1. Must be set to 0.
Bit 2: GangPowered: Indicates whether the port power
switching is ganged (set to 1) or per-port (set to 0). This is
reported in the HubDescriptor, wHubCharacteristics field,
b4, b3, b1, and b0. Default set to 0.
Bit 1: SingleTTOnly: Indicates that the hub should only sup-
port single Transaction Translator mode. This changes var-
ious descriptor values. Default set to 0.
Bit 0: NoEOPatEOF1 turns off the EOP generation at EOF1
in full-speed mode. Note that several USB 1.1 hosts can not
handle EOPatEOF1 properly. Cypress recommends that
this option be turned off for general-purpose hubs. Default
is 0, recommended setting is 1.
