of 0x00 for this command. Default is 0, recommended setting
is 1.
Bit 6: Unused: This bit is an unused, don’t care bit and can be
set to anything.
Bit 5: Fullspeed: Only configures the hub to be a full speed
only device. Default set to 0.
Bit 4: NoPortIndicators: Turns off the port indicators and does
not report them as present in the HubDescriptor, wHubChar-
acteristics 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.

wValue
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 vari-
ous 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.
