Hub Descriptor
The Hub Descriptor describes the AT43310’s Hub and ports.
Offset Field
Definition
0 bDescLength
Define size of this descriptor = 9 bytes
1 bDesriptorType
Descriptor Type = HUB_DESCRIPTOR = 29
2 bNbrPorts
Number of downstream ports = 4
3 wHubCharacteristics Hub’s characteristics:
= Individual power switching
= Hub is not part of a compound device
= Individual Port Over-current Protection
5 bPwrOn2PwrGood Time from the time power-on sequence begins
on a port until power is good on that port = 100
ms.

bHubContrCurrent
Maximum current requirements of the hub
electronics = 100 mA.
7 DeviceRemovable
Indicates if a port has removable device. All
downstream ports have removable devices
8 PortPwrCtrlMask
Indicates if a port is not affected by gang-mode
power control request.( All the AT43310’s ports
require manual SetPortFeature
(PORT_POWER) request to control the port’s
power state). The AT43310 does not support
gang mode.
