Does the MCP22xx DLL driver support USB selective suspend?

The DLLs are not USB hub drivers so they cannot request selective suspend for the USB ports to which the MCP is connected. Because the DLLs are not device drivers, they do not have to do the power management. The MCP22xx uses the Windows® driver. The suspend part is supported on the chip level and the MCP2200 and MCP2221 enter suspend mode when this is needed.
