Alan,
Thanks.I know the reason why the two irq functions are triggered
at the same time.
Below is dmesg result.
I insert a USB mouse and USB disk to the ports.
And the delay posision for ohci_irq() is :
ints = ohci_readl(ohci, ®s->intrstatus);
+ udelay(100);
When the mouse is hang, the ohci_irq() has no response.
Thanks,
Frank

That's why ohci_irq runs when you transfer file data. The data
transfer causes the EHCI controller to issue interrupt requests, and
the CPU has to call both interrupt routines (ehci_irq and ohci_irq)
whenever one of the interrupts occurs.

Please post the patch for your udelay().
