Found a Vista patch that “improves the compatibility, reliability, and stability of Windows Vista”.
Well, actually, my machine found it through “problem reports and solutions” (great Vista feature) after it crashed J
An update is available that improves the compatibility, reliability, and stability of Windows Vista
I have no idea why this update is not available as an option on Windows Update.
You might want to download it anyway to improve your “user experience”.
And a colleague of mine has pointed me towards:
Cumulative update rollup for USB core components in Windows Vista
I'll have a look around for more...
