bus reset

About this tag
The bus reset tag covers issues where a bus reset causes devices to malfunction or be re-enumerated on Windows systems. Topics include IEEE 1394 (FireWire) devices losing bandwidth after a bus reset in Windows 7 SP1 and Windows Server 2008 R2 SP1, and USB devices being surprise-removed and re-initialized when resuming from suspend on Windows 7 multiprocessor systems. These resets can lead to device removal, re-enumeration, and temporary loss of functionality. Discussions focus on troubleshooting and fixes for these bus reset-related problems in specific Windows versions.
