has no-one been able to resolve this, does rebuilding fix it?

I have same issue with GoMouse and Nvidia 8500 based graphics card.
When I installed the LinuxMCE system I had all USB devices plugged in, I noticed somewhere that someone said you should install Kubuntu and then LinuxMCE with no devices plugged in (which seem strange as it's supposed to be plug and play), and I have found no official documentation on this.
I would suggest that this is not a minor bug, it seems to be affecting quite a few users and pieces of hardware and makes the system unusable.
