2.6.21 is _very_ old and unsupported, please use a modern kernel if you
need to ask the community for help.  If you are stuck with this version
for some reason, please contact the vendor that is providing you support
for this as you are paying them for this.

If you can reproduce this with the 2.6.38 kernel release, or newer, I'll
be glad to help you out.

thanks,

Thanks. I know it's very old and not supported here. But I was hoping 
it'd be something simple
  outside of the kernel space, e.g. udev configuration. Anyway, I have a 
pretty dumb work around:
remove the ps2030.ko file. :)

Thanks again.
