I have a copperhead mouse that I can't get running. Normally I can search and figure this out but apparently everybody else has theres running.lol. The problem is that the mouse is showing up as a keyboard and a mouse. I looked at xmodmap -pp output and it says I should have 11 buttons. Various different configurations always end up saying that there should be 11 buttons instead of 7 when i run
the xmodmap -e "pointer = 1 2 3 6 7 4 5" command.

I have never dealt with anything like this before so I have no idea
what to do.Any suggestions?

I'm in slamd64 and this is my only usb device.

Was able to find the answer. Apparently the newer versions of xorg assume 11 buttons. So all I had to do was configure x correctly.

If you have this problem try this:

Option "CorePointer"
Option "Device" "/dev/mouse"
Option "Protocol" "Auto"
Option "Buttons" "7"
Option "ZAxisMapping""4 5"
Option "ButtonMapping"" 1 2 3 6 7"
Option "Resolution" "2000"
Option "Emulate3Buttons" "off"
I dont know if it has to be exactly this way but it works for me.
Still can't figure out why the bootloader says I have a copperhead mouse and a copperhead keyboard? Guess it doesn't matter. Everything works now.

Thanks for posting a fix. I was considering purchasing one of these and the thread title caught my eye.
