Hello,
I built a device that converts an N64 joystick to USB. This device works in Windows; however when I try it in SUSE 11.1 it doesn't. It is still seen by SUSE but does not create the /dev/input/js0 file. If I view the hardware information I get the following:

Does anyone know why this might be and how to fix it?

does an input device show up under /dev/input?
if there's a js0 there maybe you can just create a symbolic link.
i.e. (as root) ln -s /dev/input/js0 /dev/js0
good luck

Try looking at your dmesg logs - if there was a problem recognizing it, it should be recorded there (and if not, it should at least tell you what device file it created).

Thanks for the advice. I found out that it is something wrong with the combination of the USB hub and the joystick I am using. When I plug the joystick into the USB port directly it works and when I use the USB hub with any other device it works.
