Yes, there's something wrong with the USB driver. I'm looking into it but if someone can spot the problem please let me know.

It doesn't seem to be be present with the older single core pis. The problem presents itself as a HID message indicating extra key presses that get sent to kbdfs. It seems that the packet gets corrupted somehow.

Thanks,
Chris

Thanks for trying it out. I'm not sure about the Japanese keyboard, but that key input chattering problem is the one I'm currently hunting.

If anyone can spot the flaw in the usbdwc.c, trap.c or clock.c it would be a great help. Meanwhile, I'll keep looking at it myself, if slowly.

I'm still working out some USB kinks. Have you had any keyboard problems? Did you compile/run with 9front

Thank you verry much, Chris.

Yes, I'm using the 9pif2 kernel for terminal (now using it)
with root from tcp. I'm glad to see 4 cores here!

Yes, I have a problem to use Japanese USB keyboard.
I can use it for typing '_' '|' by patching by myself
(it may not be needed for another country).

I have one problem to use it, that is seeing chattering of keyinput,
such that
secstore: WHC
where I did not type anything before that prompt.
