UB2 fails to configure -- one or more caddies not displayed in zBUSmon

Tech Note: TN0166
Product: UB2
Version: Serial numbers < 2000
Date Added: 2005-01-21


When a system includes two or more UB2s (System 3 USB 2.0 hubs), the second UB2 will fail to initialize. A Windows operating system error will indicate that a USB 2.0 device failed to configure. You will also be unable to view one or more zBUS caddies in the zBUSmon utility's hardware diagram display.


Contact TDT to request a replacement UB2.
