4.3.2.2 Microsoft Ballpoint instead of MWS USB Virtual COM
Windows often wrongly installs a driver for "
Microsoft Ballpoint Mouse"
when connecting a USB
device althogh there is no mouse connected at all.
This results in malfunction of the driver for the MWS 55.
The problem may be solved by a change in the registry.
To perform you start the registry editor by pressing the WINDOWS KEY + R and then type
re-
gedit
and press OK.
In the next window you choose
YES
.
In the Registry editor you navigate to the following key:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Sermouse\
and right click on
Start
and choose
modify
.
Change the value to 4.
This should prevent Windows from wrongly installing the driver for the serial ballpoint mouse.
