Hello Matt,
Sorry for the late reply.I tested your USB patch on
LITE_DW(MPC823e) and found that this patch couldn't
take effect on MPC8xx directly.Maybe the reason was
that there was no CONFIG_USB_MODULE in LINUX kernel
configuration(Perhaps I use MVL 3.0 - 2.4.18 kernel).
So I changed your patch one line
#if (defined(CONFIG_4xx) && defined(CONFIG_USB)) ||
defined(CONFIG_USB_MODULE)
with this line:
#if (defined(CONFIG_4xx) && defined(CONFIG_USB)) ||
defined(CONFIG_USB_MPC8xx)
Then the USB performance improved a lot but not
perfect yet.There are few failure with USB keyboard in
boot-ups.Much better than before-only few success in
boot-ups.I listed the test result and some kernel
configuration + boot message as follows.Pls see
whether there are some faults in it.
_Test_result
Present performance: [OK--USB keybaord alive]

FAILED until next morning to work.
