Multi-hand drawing on ir-board

I have many LUMIOBOARD DVIRT-9101. It recognizes as: [ 2.309343] hid: raw HID events driver (C) Jiri Kosina [ 2.498330] usb 1-2.2.1: new full-speed USB device number 6 using xhci_hcd [ 2.720902] usb 1-2.2.1: New USB device found, idVendor=255e, idProduct=8085, bcdDevice= 2.00 [ 2.720910] usb 1-2.2.1: New USB device strings: Mfr=1, Product=0, SerialNumber=0 [ 2.720913] usb 1-2.2.1: Manufacturer: IrScreen cc [ 2.735815] usbcore: registered new interface driver usbhid [ 2.735819] usbhid: USB HID core driver [ 2.956773] input: IrScreen cc Touchscreen as /devices/pci0000:00/0000:00:14.0/usb1/1-2/1-2.2/1-2.2.1/1-2.2.1:1.0/0003:255E:8085.0002/input/input4 [ 2.956952] hid-generic 0003:255E:8085.0002: input,hiddev0,hidraw1: USB HID v1.11 Device [IrScreen cc] on usb-0000:00:14.0-2.2.1/input0 [ 2.957187] input: IrScreen cc Mouse as /devices/pci0000:00/0000:00:14.0/usb1/1-2/1-2.2/1-2.2.1/1-2.2.1:1.1/0003:255E:8085.0003/input/input6 [ 2.957338] input: IrScreen cc Keyboard as /devices/pci0000:00/0000:00:14.0/usb1/1-2/1-2.2/1-2.2.1/1-2.2.1:1.1/0003:255E:8085.0003/input/input7 [ 3.014684] hid-generic 0003:255E:8085.0003: input,hidraw2: USB HID v1.11 Mouse [IrScreen cc] on usb-0000:00:14.0-2.2.1/input1 Original program (SensStudio) only exists for Windows. I launched it with Wine, but wine doesn't support multi-touch, as I read. Then I tried many others (Openboard, Xournal++, rainbow-board_0.8.1 and many others) with Debian 11 and Ubuntu 20.04.4. Only 1 line drawing. Manufacturer's program (SensStudio) and "rainbow-board" support multi-hand writing under Windows. No super-driver is used. It detects as touchscreen, as under linux. I use Xorg, but see same problem with Wayland: https://unix.stackexchange.com/questions/710275/draw-with-multiple-fingers-styluses-simultaneously-on-a-touchscreen/742132#742132 What can I do to resolve this problem? Can I add multi-touch support in Wine (from licensed Windows of course)? Some people tell to try this, but I'm not sure It helps: https://wiki.archlinux.org/title/Multi-pointer_X
