The kernel doesn't "unstick" when the device is unplugged, it must be power-cycled. If the device is absent it will boot normally. However, upon connection, three lines will print and it will lock up as before: ugen1.2: <Kensington> at usbus1 ums0: <Kensington Kensington Expert Mouse, class 0/0, rev 1.10/1.00, addr 2> on usbus1 ums0: 4 buttons and [XYZ] coordinates ID=0 This is the "stock" kernel that was installed by sysinstall. I do not have another USB mouse to test with. The USB keyboard connected appears to function without issue. I've not written a FreeBSD problem report. Please advise if any more detail is required. >How-To-Repeat: Connect the Kensington Expert Mouse. No other action is required. >Fix: >Release-Note: >Audit-Trail: >Unformatted:
