How do I stop whatever is going on with this port so I can use it? I'm trying to get the touchscreen working on this old Fujitsu B3020D and I have the issue all but solved. I'm just snagged on the OS refusing to open the port for testing because it's supposedly busy.... only it shouldn't be busy. Can somebody please help?

I'm using Ubuntu 11.10
