That helped indeed.

Changing

        case USB_VENDOR_ID_DWAV:
                /* These are handled by usbtouchscreen. hdev->type is probably
                 * HID_TYPE_USBNONE, but we say !HID_TYPE_USBMOUSE to match
                 * usbtouchscreen. */
                if ((hdev->product == USB_DEVICE_ID_EGALAX_TOUCHCONTROLLER ||
                     hdev->product == USB_DEVICE_ID_DWAV_TOUCHCONTROLLER) &&
                    hdev->type != HID_TYPE_USBMOUSE)
                        return true;
                break;

to

        case USB_VENDOR_ID_DWAV:
                /* These are handled by usbtouchscreen. hdev->type is probably
                 * HID_TYPE_USBNONE, but we say !HID_TYPE_USBMOUSE to match
                 * usbtouchscreen. */
                if (hdev->product == USB_DEVICE_ID_DWAV_TOUCHCONTROLLER &&
                    hdev->type != HID_TYPE_USBMOUSE)
                        return true;
                break;

did the trick.
I also commented the dev id in usbtouchscreen.c out.

//      {USB_DEVICE(0x0eef, 0x0001), .driver_info = DEVTYPE_EGALAX},

Thanks,
Sebastian Dalfuß
