SYMPTOMS

A 1394 storage device with more than one Logical Unit Number (LUN) may stop functioning if another 1394 device is either inserted or removed from the computer.

CAUSE

When a 1394 bus reset occurs after a device is inserted or removed, the 1394 mass-storage driver (Sbp2port.sys) must reconnect to each LUN on a 1394 mass-storage device. 1394 mass-storage devices can only handle one reconnect request at a time. The Sbp2port.sys driver often submits more than one request a time, one for each LUN on the device. The mass-storage device ignores the multiple reconnect requests, and only reconnects the first LUN. Because of this, other LUNs on the device are not reconnected, and become non-functional.
