Bit 7: IllegalHubDescriptor. For GetHubDescriptor request,
some USB hosts use a DescriptorTypeof 0x00 instead of
HUB_DESCRIPTOR, 0x29. According to the USB 2.0
standard, a hub must treat this as a Request Error, and STALL
the transaction accordingly (USB 2.0, 11.24.2.5). For systems
that do not accept this, the IllegalHubDescriptor configuration
bit can be set to allow CY7C65620/CY7C65630 to accept a
DescriptorType of 0x00 for this command. Default is 1.
Bit 6: CompoundDevice. Indicates whether the hub is part of
a compound device. This is reported in the HubDescriptor,
wHub-Characteristics: b2. Default set to ’0’.
Bit 5: Fullspeed. Only configures the hub to be a full speed
only device. Default is set to ’0’.
Bit 4: NoPortIndicators. Turns off the port indicators and does
not report them as present in the HubDescriptor,
wHubCharacteristics b7 field. Default is set to ’0’.
Bit 3: Reserved. Set this bit 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 is set to ’0’.
Bit 1: Reserved. Default is set to ’0’.
Bit 0: Reserved. Default is set to ’0’.
