Apprently on 2.6 both PS/2 and USB mice appear at /dev/input/mice. I myself has used two USB mice with no problems. No, I don't know what the resolution is, but some googling may help. ================================================= Based on these clues I did checkout the 2.6 kernel forum archives and found this is a known problem. The culprit seems to be the synaptics touchpad. Its driver doesn't pay nice with code that is in kernel 2.6. I was able to solve the problem by appending the kernel option, "psmouse.proto=imps". Seems to work fine now. I found I could check out this option by catching the system at boot time. Press any key before the delay time expires. That allows a choice of several options, one of which is 'a' (as in "append") which then allows me to specify that kernel boot option just for this boot instance. Once I was able to sort out that solved my problem, I edited /etc/grub.conf and added the option to the kernel boot line ... to make that option effective for every boot. By the way, the Synaptics touchpad does still work okay. Thank you, gentlemen - one and all - for your good counsel!
