Hi again,
Oops. I missed the dmesg.

Hi Alan,
<snip>
This all makes sense. Since Huacai's patch was originally intended to
fix Loongson's OHCI implementation, I was beginning to suspect if it
exists for OHCI implementations found on older x86 platforms, say,
AMD's SB600/700 series south bridges. Also to see if this issue is
shared between OHCI and UHCI.
I have purchased a motherboard to test this and will report back as
soon as I get my hands on it.
I have since purchased a Gigabyte GA-78LMT-S2 motherboard with an SB710
south bridge, the USB OHCI controllers and USB device tree are as follows:

Long story short - wake from keyboard via OHCI works (as opposed to what
we have found with the Loongson XA61200 motherboard, which also has an
OHCI controller, but in its 7A2000 bridge chip).
Huacai, I suspect that we are looking at a Loongson-specific issue.
For your reference, here are the equivalent logs which I have supplied
for the ThinkPad X200s (which, according to my previous testing, failed
to wake up from an external keyboard plugged into its UHCI interface).
The OHCI to which the keyboard is connected to on this motherboard
corresponds to PCI device 0000:00:13.1:
