Sun patches broke my KVM!

Hi Folks,

I recently had to apply a few official Sun patches to three systems to
fix a kernel panic on return to OBP. The patches worked great and I
can now drop to OBP with no issues... however... since applying the
patches my KVM mouse/track-pad stopped working on all the systems!
Its a non-Sun device, but it works fine on many pre-patched systems
and where ever I find the device on the Internet its listed as being
Sun compatible. The keyboard works fine, but the track pad fails to
move the mousen at all - I can't test the buttons as I can't hover
over anything to click. I tried connecting a Sun Type 6 USB keyboard
and mouse to the system and they work with no issues.

The KVM is a Meridian RKP117-801E 1u 17inch monitor keyboard draw,
8-port KVM - I think its basically a generic KVM branded Meridian as
if you do a Google for RKP117-801E you will see many makes of KVM -
these all look the same. Its basically a black 1U draw with a 17" LCD
display, a keyboard and mouse with a built in KVM switch, all
connected to the systems via USB and the Monitor.

The patches I applied were - 115553-13, 117171-10, 117171-12 and
117418-01.

I know the benefits of using a serial console or remotely
administrating the servers etc. etc. but these particular systems need
to be used with a keyboard and mouse so I really need to get this
issue fixed.

Is there a config file that I can put back to how it used to be, or a
settings file that I can alter to make it see the USB track pad at
all? Is there a way I can see if the USB device is seen at all, or
are there any other things people can suggest?

Thanks,

Andrew McCall
