I'm working on usb communication on the Altera DE2 kit, have to follow the instructions on the wiki NIOS, the source linux I used is 20090808
sytem_0. ptf file from vga mouse host projects in DE2_system DE2 CD first make,download and boot then detect the hub 1-0: 2 ports detected the second,with the above zImage, download and boot it can't detect usb hub 1-0: 1 port detected i don't understand why this error I followed the instructions on the forum is how to skip clock = check immediately return 1 after variable declaration in the function file hc_reset of isp1362-hcd.c but still not detect the usb Who solved this problem can you help me?static int isp1362_hc_reset(struct usb_hcd *hcd)
{
int ret = 0;
struct isp1362_hcd *isp1362_hcd = hcd_to_isp1362_hcd(hcd);
unsigned long t;
unsigned long timeout = 100;
unsigned long flags;
int clkrdy = 0;
ret=1;
pr_info("%s:\n", __func__);
if (isp1362_hcd->board && isp1362_hcd->board->reset) {
isp1362_hcd->board->reset(hcd->self.controller, 1);
msleep(20);
if (isp1362_hcd->board->clock)
isp1362_hcd->board->clock(hcd->self.controller, 1);
isp1362_hcd->board->reset(hcd->self.controller, 0);
} else
isp1362_sw_reset(isp1362_hcd);
/* chip has been reset. First we need to see a clock */
t = jiffies + msecs_to_jiffies(timeout);
while (!clkrdy && time_before_eq(jiffies, t)) {
spin_lock_irqsave(&isp1362_hcd->lock, flags);
clkrdy = isp1362_read_reg16(isp1362_hcd, HCuPINT) & HCuPINT_CLKRDY;
spin_unlock_irqrestore(&isp1362_hcd->lock, flags);
if (!clkrdy)
msleep(4);
}
spin_lock_irqsave(&isp1362_hcd->lock, flags);
isp1362_write_reg16(isp1362_hcd, HCuPINT, HCuPINT_CLKRDY);
spin_unlock_irqrestore(&isp1362_hcd->lock, flags);
//if (!clkrdy) {
if (clkrdy) {
//end of edit
pr_err("Clock not ready after %lums\n", timeout);
ret = -ENODEV;
}
return ret;
}

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- Mark as New

I solved this problem, after downloaded file .sof to board, you should press KEY0 (reset)
then i downloaded zImage and boot : detected 2 port and could access file on USB http://nj5.upanh.com/b5.s3.d1/ebaca0ea474ef479baf99cc2677fb488_42190205.untitled.jpg
