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
