DEVICE=C:\OS2\BOOT\USBECD.SYS /D:056A:508C:#### /N:$FINGER$ /S /V
DEVICE=C:\OS2\BOOT\USBECD.SYS /D:056A:508C:#### /N:$STYLUS$ /S /V
(You have not provided enough hardware info that would allow to find out the device release but I think that last parameter of /D is optional)

Hello Lars
I have the Tablet/Laptop device PCI report here: https://www.os2world.com/wiki/index.php/Lenovo_Miix_510-12ISK_Hardware_Report
I can not find any "056A:508C" device with PCI.exe or lsusb. What other report do you suggest me to try to find the ID of this device.
I'm still not sure if the touch screen and pen support is USB or COM related.

While searching the internet I found "GNU Linux Debian 11 hardware review - Lenovo Ideapad MIIX 510 12ISK_dmesg.txt" which I attached here.
It appears there as a USB device and its device driver statement would be:
--- Code: ---DEVICE=C:\OS2\BOOT\USBECD.SYS /D:056A:508C:0001 /N:$LENOVO$ /S /V
--- End code ---
To be on the save side use the wildcard character # for the device release number:
--- Code: ---DEVICE=C:\OS2\BOOT\USBECD.SYS /D:056A:508C:#### /N:$LENOVO$ /S /V
--- End code ---
After reboot you may run the USBWRITE.CMD script to obtain and display the device descriptor, configuration descriptors and associated interface and endpoint descriptors. Use USBWRITE $LENOVO$ for this particular USB device.

Hello Wim
I tried on my config.sys
--- Quote --- DEVICE=C:\OS2\BOOT\XSMOUSE.SYS
DEVICE=C:\OS2\BOOT\AMOUSE.SYS STYPE=XSMOUSE$
...
DEVICE=C:\OS2\BOOT\USBECD.SYS /D:056A:508C:#### /N:$LENOVO$ /S /V
--- End quote ---
When I run "usbwrite $LENOVO$" I get:
--- Quote --- SYS0031: A device attached to the system is not functioning.
--- End quote ---
Just in case I'm attaching my testlog report.
FYI: Since this machine is dual boot, I had checked that on Windows 10 the touch screen and pen support works.

Hallo Martin,
Alas, in ..generic.log the touch screen device does not show up as a USB device nor as a COM device. In Linux Debian it shows up as an SMBus attached I2C device from Synopsys Designware. That system knows how to deal with that and represents it as USB device 056A:508C:0001 (which we tried and failed on our system). As far as I know there is no software to deal with I2CBus/SMBus devices from an application in our operating system. Therefore pen and touch cannot be supported on this laptop.
Regards, Wim.
Martin Iturbide:
Thanks for the reply. I will move on to try a different touch screen laptop.
But I would like to know, is there a way in ArcaOS to generate some report that will list the touch screen and pen devices like the report that was tool from Linux Debian? (that report that Wim shared from the internet). LSUSB does not show it in this case also.
I'm still trying to find ACPITREE, but I don't know if that is the right tool for this, or where to get it.
Regards
