My Thinkpad 25-2, based on a Thinkpad T480 (I build my own Thinkpad based on a T480 with the Palmrest, Keyboard, Touchpad etc. from the Thinkpad 25, all the inside electronic is a T480 with 32 GB RAM, Nvidia MX150, 2 TB SATA SSD etc. USB Hardware see Screenshot; unfortunately sound is not working so far, have to dig there):
USB 3 Driver work very well. USB DVD is working, USB DisketteDrive is working.
PCI.EXE attached.
Well Done!
