Connect the Wacom tablet to the serial (Com, Serial) port and work through the usb-com adapter.

When switching from desktop to laptop, there was a problem connecting the Wacom Intuos tablet. My model is quite old and is connected via a COM port, which has not been used in laptops for a long time. Buying a new 6 × 8 inch tablet just because of usb makes no sense. Easier to buy com-usb adapter. Wacom guarantees work only with Keyspan , but they are quite expensive. But there are many cheap adapters, most of which are assembled on a Prolific chip. In the end, took the TRENDnet TU-S9 . Everything worked with him, I think there should be no problems with other “Prolifics” either.

Now about the difficulties of connecting

The Internet is full of tales of black magic and tambourine dances with Wacom connections . "Wacom Tablet Properties" in the Control Panel does not see the tablet in focus. Having tormented the whole day, everything finally worked. Drivers for Wacom took here . The entire 6.x series should work. I connected the adapter via com-usb, but I think the com port will be the same.

So, what to do:

1. We delete all Wacom drivers from the system .
2. If usb-com adapter is used, set its driver.
3. Install the Wacom driver .
4. Create a Wacom_Tablet.dat file with the following content:
   PrefsFileVersion 4
DriverOn1Off0 1
DriverLanguage 13
LeftHandedMouse 0
FunkyButtonMode 0
NoStartWarnings 0
HowManyTablets 1
TabletType 0
TabletModel 201
CommPort COM1
TabletOn1Off0 1
TabletPhysicallyOn 1
TabletFlags 0
HowManyTransducers 0

   change the port number in the CommPort to the port used by the tablet. When using the usb-com adapter, the com port can be checked in the Control Panel, System, Hardware tab, Device manager there we look in Ports.
5. Copy this file to
   %USERPROFILE%\Application Data\WTablet\Wacom_Tablet.dat

6. Restart the Wacom service.
   It is better to write a bat file for this. It will be useful to us more than once. Let's say wacom.bat . There we write
   net stop "TabletServiceWacom"
net start "TabletServiceWacom"

7. If the tablet does not respond to the pen, overload the computer.

If something still does not work, check the port number in %USERPROFILE%\Application Data\WTablet\Wacom_Tablet.dat . Sometimes the driver changes it.

After rebooting, Windows may offer to install new hardware, close this window and do not install anything. Sometimes nothing works from it.

When you reconnect the tablet, most likely it will not work. Here you will need wacom.bat created earlier. Well, or just reboot.
