I'm not sure you'll get Touchscreen working in Catalina or Big Sur without some add-on software. It certainly was the case for my Skylake E7270 for which Touchscreen worked OOB up to Mojave. @Maxd13, your SysInfo screenshot seems to show you've changed your SMBIOS from MBP (which would have been correct) to that of an iMac (which would be incorrect). Is that the case?

I think Maxd13 is using USBInjectall instead of USBMap or USBPort.kext I can confirm the touchscreen model uses HS08 Try this kext USBPorts_7280.kext.zip
