    Jamie> Here's the relevant bits of my .config,

    Jamie> CONFIG_INPUT_JOYDEV=m

check.

    Jamie> CONFIG_INPUT_JOYSTICK=y

check.

    Jamie> CONFIG_USB=y

Mine says m.

    Jamie> CONFIG_USB_DEVICEFS=y

check.

    Jamie> CONFIG_USB_UHCI_HCD=y

Mine is m.

    Jamie> CONFIG_USB_HID=y

Mine is m.

    Jamie> CONFIG_USB_HIDINPUT=y

check.

    Jamie> What kind of USB controller do you have again?

It looks like it's NEC.  I couldn't get the one on the motherboard to
work, so finally I spent $20 on a PCI board with 4 of them.

    Jamie> I'm looking at your lsmod output from the pyddr list, and I see,

    Jamie>   ehci_hcd               29824  0
    Jamie>   ohci_hcd               20864  0 
    Jamie>   uhci_hcd               31112  0 

    Jamie> I don't think you want both ohci_hcd and uhci_hcd (probably keep uhci).

No, it looks like it's ohci_hcd it wants.  When I removed it, I
couldn't do jstest any more, and when I put it back I could.

    Jamie> Also, try this (before and after dumping ohci_hcd),

    Jamie>  $ ls /sys/class/input/js*

dev  device  driver

    Jamie>  $ cat /sys/class/input/js0/dev

13:0

It doesn't seem to matter whether I have the extra hcd modules or not.
