USB to Serial converter driver (Windows Update)
If you've got a USB to serial converter that uses the FTDI chip, DON'T download the windows update for it!!
It will cause BSODs and random programs to shutdown!
I sent a report to MS and their bot decided it was a video device driver problem. It wasn't.
The BSOD said the error was caused by "ftdibus.sys" which is a driver file for the USB to serial converter.
Hope this stops anyone else having this problem...
