FTDI devices can support remote wake-up as long as the feature is enabled in the device EEPROM. The driver can be made to ignore any EEPROM settings for remote wake-up by setting bit 4 of the ConfigData field in FTDIBUS.INF as shown below:

   [FtdiBus.NT.HW]
   AddReg=FtdiBus.NT.HW.AddReg

   [FtdiBus.NTamd64.HW]
   AddReg=FtdiBus.NT.HW.AddReg

   [FtdiBus.NT.HW.AddReg]
   HKR,,"ConfigData",0x00010001,16


which corresponds to the registry entry

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\USB\{Device VID, PID and interface}\{Serial number}\DeviceParameters\ConfigData  

In addition, it is possible to specify that the system should be able to turn the device off to save power. This can be enabled by setting bit 3 of the ConfigData field in FTDIBUS.INF as follows:

   [FtdiBus.NT.HW]
   AddReg=FtdiBus.NT.HW.AddReg

   [FtdiBus.NTamd64.HW]
   AddReg=FtdiBus.NT.HW.AddReg

   [FtdiBus.NT.HW.AddReg]
   HKR,,"ConfigData",0x00010001,8


which corresponds to the registry entry

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\USB\{Device VID, PID and interface}\{Serial number}\DeviceParameters\ConfigData  

These options are also configurable after installation through the Power Management tab of the USB Serial Converter properties page which is available through the device manager.
