fatal trap 12: page fult in kernel module
fatal code: page not present

processor flags: interrupts enable, resume, IOPL=0

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!

State-Changed-Why:  
We need more & correct information. 

1. There is no ultp device in CURRENT, did you mean ulpt(4)? 
2. Good Bug reports should contain a backtrace. Read more about Kernel  
debugging here: 
http://www.freebsd.org/doc/en_US.ISO8859-1/books/developers-handbook/kerneldebug.html 
3. Your PR should contain information what kind of devices you are connecting, 
e.g. the output of dmesg 
4. Did you try to use your device with USB1 (by removing ehci from your  
Kernelconfig)?
