Thanks, Pavel.  I will try all that right now and let you know how it goes.

Hi, Pavel.

Thanks for the suggestions. They did not work, though.  I still think what I am experiencing is similar to Pete 
Mackereth because I am using a Microsoft USB mouse (3-button) and a Keytronic USB keyboard. But the QNX4 2011 install CD
 can't see them as USB, and if I turn on searching for USB plug and play in diagnostics mode the installation freezes.  
If I let QNX4 install without USB plug and play but with the bios turning on USB mouse and keyboard support the QNX4 
installation sets the keyboard and mouse both to PS/2.  The keyboard works fine, but when photon launches the mouse is 
completely erratic going all over the place and right and left clicking constantly on all movement.

The bios versions are:
CMOS - Phoenix Award Bios v6.00PG
AHCI Bios - Not installed
ATA - IT8211ATAPI Bios v.1.3.1.67

If I change /etc/config/trap/input.1
old:  kbd fd -d/dev/kbd ps2 -r kb -2
new: kbd fd -d/dev/kbd ps2 kb -2

The mouse still has the erratic behavior. I also tried the equivalent change to /etc/config/bin/Input.1 just in case, 
but that also did not help.

Next I put your latest devu-mouse driver in the /bin directory and added:
io-usb &
devu-mouse &
to the /etc/config/sysinit.1 file before photon initializes.

And I replaced the /etc/config/trap/input.1 file with one which has:
kbd kb
msoft fd -d/dev/usbmouse0

This had the fatal error of not allowing me to use the keyboard at all, and I could not even use phindows to get into the node to type.  It was stuck at the "login:" prompt.  But fortunately I kept an alternate boot and was able to restore it.  Before restoring it I tried turning off USB mouse support in the bios to see if that would let QNX4 see it as USB instead of PS/2, but that did not help. It was still stuck in the login prompt without ability to type.

I've put it all back, but as it is now QNX4 only sees the mouse and keyboard as PS/2 and does not see them as USB even though they are USB.  In photon the mouse is completely erratic, but I can use phindows from a Windows system as an alternate method to use GUI's and type.

Any suggestions you can offer from here will be greatly appreciated as we plan to order our QNX4 licenses going forward for these PC types because we need the PCI-E slots in them for the encryption cards. Right now Photons is useless and even dangerous with the mouse as it is.

Thanks very much.
