USB on altera DE2 board

i used file sytem_0.ptf from DE2_NIOS_HOST_MOUSE_VGA on DE2_SytemCD.v1.6,

the OS is Ubuntu 10.10

version quartus 9.1sp1 & nios ide 9.1 on Window to download zImage and boot

I read instructions on USBHost (altera wiki)

use ISP1362_CTRL.v to create new components named "ISP1362" ,

set setup time,hold time... = 100 ns,

add 2 interfaces interrupt sender & interrupt sender to avalon_slave_0 & interrupt_sender_1 to avalon_slave_1, set NATIVE on avalon slave_0 &1, set type "irq_n"

set OTG_signal to " conduit-end" and their types are "export"

then complete this component, I add it to sopc, name "ISP1362"

But have no effect, still detect 1 port hub1-0, who can supported me to solve this problem?

I'm not good at English, sorry
