PCI Simple Communication Controller on Biostar M7VKQ

I've been trying to get my LaserJet 1100A working and now when I reboot
the computer it tells me it is finding new hardware, namely the "PCI
Simple Communication Controller". Previously this item showed up in
the device manager with the big yellow ? beside it along with a
parallel device which just appeared while I was messing with the LJ1100
drivers. So I tried deleting both of these problem devices.

Now when I boot, it detects new hardware, the "PCI Simple Communication
Controller" and I can't find a driver to go with it. I have no idea
what piece of hardware it is referring to and I see by web searches I
am not the only one with this problem. But no good info on how to fix
the issue.

What is this and where do I find a driver?
