kill usbd, yes, it's not supported. I mean, if you kill it and it fails,
the man page says that you are not supposed to do that. But do it anyway :)

Then, usb/usbd -dd
and see what happens.

BTW I assume that you are not using a usb kbd/mouse to execute such commands.
If you are, then we can set usbdebug in plan9.ini, IIRC, and go from there.
