Game controller/joystick won't populate in /dev
 
I have an EMS Dual-Shooter PS2 -> USB converter, with a regular playstation 2 controller attached.

There is no js* device listed in either /dev or /dev/input when I plug the controller in.

I'm running Slackware64 13.0, kernel 2.6.29.6. I also have the joystick driver here installed.

I have the joydev module inserted and running:
Code:
bash-3.1# lsmod|grep joy
joydev                11968  0
this is the relevent section of lsusb -v:

dmesg reports this when I plug in the device:
Code:
usb 7-2: new low speed USB device using uhci_hcd and address 5
usb 7-2: string descriptor 0 read error: -32
usb 7-2: string descriptor 0 read error: -32

edit: I have also tried doing "mknod input/js0 c 13 0" in /dev, but then "cat /dev/input/js0" returns "cat: /dev/input/js0: No such device". I have also inserted the "analog" module along with joydev.

Have you tried the stuff here?
http://www.linux-usb.org/USB-guide/x194.html

It does mention a kernel rebuild, you may want to check if your kernel is up to it.

Thank you for your reply. Yes, I've tried the things mentioned in that guide. I'm pretty sure my kernel already supports the joystick functions that I need though, so I don't think a kernel rebuild is necessary.

No /dev/input/js* device means no go. Try

cd /dev/input
sudo mknod js0 c 13 0

but the lasting cure is a udev rule, in wherever your system has a udev/rules.d directory.
