Dear All,

 

I use NEC uPD720101 USB chip, 2 OHCI and 1 EHCI, I also have turn on the
following options in kernel menuconfig:

[*] USB Support / support for Host-side USB

[*] USB Support / USB device filesystem

[*] USB Support / EHCI HCD (USB 2.0) support

[*] USB Support / OHCI HCD support

[*] USB Support / USB HID Boot Protocol drivers / USB HIDBP Mouse (simple
Boot) support

 

But when I plug-in a USB mouse, then Kernel Oops..

I use MPC8241 CPU, and there are three USB ports sharing the same IRQ on my
borad.

 

Thanks,

Johnson Cheng
