(Because the joystick device is not listed in the output of command
'lspci', I think I cannot use the PCI passthrough  to achieve it?)
No, unless you passthrugh the whole PCI device that is your USB controller.

âAfter I use `xl create dom1.cfg`,  no /dev/input/js0 was created in the
guest domain 1.
(I have the /dev/input/js0 in dom0.)
(I also tried to use usbdevice=['tablet','host:1.8','host:046d:c21f'] as
shown in xen's website and still couldn't see /dev/input/js0 in guest
domain 1.)
What does lsusb in the guest domain says, after you attach the USB device to it?

Have you tried to hot-plug it instead of specifying in the config file?
