Hi Paolo, thanks for your reply! If you build with simply ARCH=um, you'll build a x86_64 UML binary. And currently, there's 0 support to 32-bit binaries inside 64-bit hosts. This is why it's failing for you. Ah ha! But the solution is easy: clean your kernel tree and start over, adding to

I have learned that the newest linux kernel supported by the usb (hdc-uml) patch is the 2.4.19. Aparently since that version the usb API/framework/thing/model inside the kernel have changed in a way that the patch was driven ineffective. I didn try it with newer kernels yet. Maybe tomorrow
