That's normal for a USB joystick (or wheel, or other generic
knobs-and-buttons-and-switches HID device).

VICE only knows about the old-style joystick interface; it needs some
code written to handle USB controllers (including, sadly, some
mechanism to pick which joystick/pad to use for what, and which
buttons map where). The interface to use is the stuff in libusbhid;
see usbhid(3). You can probably crib from XMame's USB joystick
support, in that package's src/unix/joystick-drivers/joy_usb.c.
