ns558 mis-detects gameport

[Neil Darlow <neil@darlow.co.uk>]

Hi All,

I am passing on this information at the request of Daniel Drake (Gentoo kernel 
ebuild maintainer).

My hardware is an ASRock K7S41GX motherboard with Athlon XP2200+ CPU
running 2.6.12 on Gentoo GNU/Linux 2005.0. My gamepad is an Heroic HC 3100 
2-axis, 4-button digital model with Turbo features.

The CVS version string of ns558.c is:
$Id: ns558.c,v 1.43 2002/01/24 19:23:21 vojtech Exp $

My motherboard features a generic PC/ISA gameport at BIOS-selectable
addresses of 0x200 or 0x208. I have built my kernel (using Gentoo's genkernel) 
to include the Joystick Interface, Generic PC/ISA Gameport and Analog 
Joystick support as modules which are loaded at boot by coldplug/hotplug 
logic.

If I manually modprobe ns558 (which loads gameport), analog and joydev after 
boot my gameport is detected. If I let coldplug/hotplug load the modules at 
boot then ns558 fails to detect my gameport.

If I unload, and then reload, ns558 using coldplug/hotplug at boot then ns558 
detects my gameport correctly. My module loading setup and dmesg output for a 
ns558 insert-remove-insert cycle are as follows:

  options analog map=gamepad
  above analog joydev
  pre-install analog modprobe -r ns558; modprobe ns558

  gameport: NS558 ISA Gameport is isa0200/gameport0, io 0x201, speed 806kHz
  pnp: Device 00:0a disabled.
  ns558: probe of 00:0a failed with error -16
  gameport: kgameportd exiting
  pnp: Device 00:0a activated.
  gameport: NS558 PnP Gameport is pnp00:0a/gameport0, io 0x200, speed 806kHz
  input: Analog 2-axis 4-button gamepad at pnp00:0a/gameport0 [TSC timer, 1786
    MHz clock, 1299 ns res]

At https://www.redhat.com/archives/fedora-list/2005-January/msg04967.html the 
same problem is reported for 2.6.10 on Fedora.

Is a fix or workaround, other than what I'm doing already, available for this 
problem?

Regards,
Neil Darlow
