Bug 30502

if logitech joystick usb is attached to system, next program that runs will panic.

device "Logitech Wingman Digital 3D" product 0xc207 vendor 0x046d release 0x0104
I have tried to follow kernel debugging section of handbook, and managed to get this output :

Fatal trap 12: page fault while in kernel mode
fault virtual address   = 0x0
fault code              = supervisor read, page not present

uhci0: <VIA 83C572 USB controller> port 0xe400-0xe41f irq 9 at device 7.2 on pci0
usb0: <VIA 83C572 USB controller> on uhci0
usb0: USB revision 1.0
uhub0: VIA UHCI root hub, class 9/0, rev 1.00/1.00, addr 1
uhub0: 2 ports with 2 removable, self powered

problem seems very much like http://www.FreeBSD.org/cgi/query-pr.cgi?pr=27370 but patch there did not work for me (deleted the 2 lines and remade kernel)
i can try to provide additional information if requested

How-To-Repeat: have usb logitech joystick plugged into system.
