There is a limited number of USB ports available on some chipsets. Therefore, manufacturers sometimes build internal USB 2.0 hubs into their computers. If a Bluetooth dongle is connected to a USB 2.0 hub, the Bluetooth device may stop working intermittently. This occurs when a USB command times out. The computer hardware configuration determines the frequency of the time-outs.
Note This update includes additional error code handling to address the Bluetooth USB hub error conditions and the driver reset issue.
