Hi everybody!
I seem to have killed my mouse... I've certainly fixed more difficult
problems than this... But, at the moment, this has got me buffaloed.
I've ruled out any sort of hardware problem... As the mouse works fine on
the same COM port in different OSes.
I'm running a custom kernel, with my serial port probed on sio0
(correctly, I might add... same port/irq as it has always been)
The mouse worked fine in FreeBSD up until I changed some hardware around.
Namely, I removed a CD-ROM, some expansion cards (none of which happened
to be an IO controller :-) and added another network card. I did rebuild
my kernel when I removed support for the hardware I removed and added
support for the new network card. Other than that, I'm using the same
mouse, on the same serial port. Again.... The mouse worked perfectly
before, and STILL works in other operating systems that are using all the
system hardware on (to the best of my memory) the same hardware settings.
Unless I missed it, there shouldn't be any hardware conflicts (the only
new hardware, my NIC, is on IRQ 12. sio0 is on IRQ 4). I'll attach my
dmesg output for your perusal.
moused -d /dev/cuaa0 reports that it cannot determine the mouse type.
It's always been set to auto and worked without a hitch. I went through
the various mouse types in sysinstall with no luck.
Hmm.... Just looking at my dmesg output now.. I see "stray irq 7" messages
reported by the kernel. Funny... Never saw those before. See my other
thread "Stray IRQ 7 error". These errors, and "acd0:" errors occur when
running sysinstall.
Here's dmesg:------------------------------------------------------

Any help would be, of course, very much appreciated. It is always
beneficial to remain in control of one's pointer.
