Windows 2000 ConnectMultiplePorts Registry Key

If the ConnectMultiplePorts registry key is set to 1, USB devices may not work on the system. Also, the following errors can be displayed by the System event Log:

• Service Control Management, ID=7009, Timeout (30000 ms) waiting for Elo TouchScreen Service Activation
• Mouclass, ID=9, Impossible to activate interrupts on \Device\PointerClass0

This can be corrected by running regedit and changing the following registry key from 1 to 0:

HKEY_Local_Machine
    System
          CurrentControlSet
               Services
                    Mouclass
                         Parameters
                              ConnectMultiplePorts

Double-click the ConnectMultiplePorts text to edit the value, then close the registry editor and reboot the system.
