Wacom Virtual Hid Driver

Hello Guys,

after playing around with JInput I am stuck, maybe someone can help me out. I would really appreciate it.

I am using a Wacom Intous3-tablet (with the latest driver) and want to get rotation information of the pen.
When I start the jinput-test-app (or my own little test) I get the Wacom Virtual Hid Driver, probably the tablet and the Wacom Mouse, the pen itself.
The Wacom Mouse-Controller only delivers x/y-coordinates, the rotation, it seems, needs to be delivered by the tablet.
Moving the pen on the tablet has no effect on anything but the Wacom-Mouse-Output.

When starting the test-app I get an error message

Failed to initialize device Wacom Virtual Hid Driver because of: java.io.IOException: Failed to acquire device (8007001e).

Somewhere else I read this is not an error but a warning message, but taking into consideration that this device is not giving any output at all, this might be the error.

Does someone have an idea what causes the error and how to solve it?

Thanks a lot!

I believe that error code means that something else has the lock on the device, so JInput can’t get it. This means that there is no way the device will work with JInput at that time. If there is not other application locking the device, it should work i think. I’ve not tried with that pad though.

Hello Endolf,

thanks a lot for your answer.

I checked the code and found it’s DIERR_INPUTLOST.
If other applications would be locking, shouldn’t it be DIERR_OTHERAPPHASPRIO ?

Do you have an idea what could cause this error and, if its the locking error, how to find out which applications lock the device? I already terminated all processes called “Wacom_something”.

Thanks,
Nono
