>Description:
fatal trap 12: page fult in kernel module
fatal code: page not present
stack pointer: 0x10:0xcc05ccc
frame pointer: 0x10:0xccc105cc8
code segment: base 0x0, pres 1, def 32, grant 1, DPL 0
processor flags: interrupts enable, resume, IOPL=0
current page: 37(usbtask)
trap = 12
panic: page fault
>How-To-Repeat:
every time  when try to use ultp0 device.
also, report unconnected  port(i use only ultp0) but kernel said:
"ultp1: at uhub3(addr 2) disconnected ehci_idone: need toggle update status: 00080248 ustatus: 80028d80 ulpt1 detached"
but on ultp1 no device at all!
