See Literature slls413e    
TPS2041B   Single-Channel Current-Limited Power Distribution Switch   PCMCIA AND USB - USB POWER SWITCHES   TPS2041used for ganged-port power management provides overcurrent protection for the downstream ports.
See Literature slls413e    
TPS2044B   Quad Current-Limited Power Distribution Switches   PCMCIA AND USB - USB POWER SWITCHES   The overcurrent protection can be provided by a TPS2044 quad device or a TPS2024 single power switch. It is recommended to use TPS2041B instead of TPS2024 and TPS2044B instead of TPS2044.
See Literature slls413e Recommend keeping the outputs individually connected to all ports instead of ganged together
