A recent Vista update is causing headaches for users with USB devices.

Microsoft last week re-released a software update intended to provide performance and reliability enhancements for Windows Vista -based and Windows Vista Service Pack 1-based systems. It was one of eight security bulletins and updates the company made available on April 8.

Users who installed the update, however, soon found their USB devices unresponsive, particularly mice and flash drives. Removing and re-installing the programs reportedly did not immediately solve the problem.

Microsoft confirmed the bug, but declined to provide further details.
