With this patch, and the CAM patches still in place, the USB bus works 
fine, but hald never sees any attach/detach events, even after restarting 

I reverted the CAM patches and tested again with the same result.  So this 
patch to hald does stop the CAM sg errors, and prevents the USB from 
wedging.  It just doesn't detect attach events.
