"chmod 666" is actually what you want, but 777 should work in this
case as well.

I just went through getting some USB joysticks working on Linux, and
figured out the "right" way to do it so that the permissions get set
each time I reboot.

It's in "/etc/udev/rules.d/50-udev-default.rules".  I changed this
section:

  # input devices
  #KERNEL=="mouse*|mice|event*",  NAME="input/%k", MODE="0640"
  KERNEL=="mouse*|mice",      NAME="input/%k", MODE="0640"
  KERNEL=="event*",       NAME="input/%k", MODE="0666"
  #
  #KERNEL=="js*",         NAME="input/%k", MODE="0644"
  KERNEL=="js*",          NAME="input/%k", MODE="0666"


But there's another section above it for serial devices that could
be changed in a similar manner.
