Vista SP1 hits USB Snag

Microsoft has rolled out Vista Service Pack 1 in all supported language versions, but some existing SP1 users have had problems with USB-based devices after applying a security patch.

Users who have installed SP1 report that USB-based devices such as mice and flash drives stopped working properly after Microsoft's April 8 security patch was applied, according to various circulating news accounts. Removing the drivers and reinstalling them reportedly does not fix the problem.

It's not clear how widespread this USB problem may be, but
Microsoft is officially on the case.

"We are aware of concerns that a recent Microsoft update may be
causing problems with USB devices," stated a Microsoft spokesperson
by e-mail. "We are investigating the matter and at this time do not
have any additional information to share."

For those installing Vista SP1, Microsoft recommends using
Microsoft Windows Update, which facilitates the upgrade by checking
to see if updated drivers are present first.

"Windows Update will recognize PCs with known problematic
drivers and postpone downloading Windows Vista SP1 until the PC has
updated drivers or other applicable updates," explains a Microsoft
TechNet primer.

Users can access Windows Update manually to install Vista SP1,
but Microsoft has not as yet offered Vista SP1 via automatically
delivered updates, even though Vista SP1 is now available in all
supported languages.

The alternative way to install Vista SP1 is to get it from the
Microsoft Download Center. Microsoft explains current SP1 update
options here.
