This happens when the usb keyboard/mouse driver misinterprets the HID
protocol description in the device configuration. Incidentally this
is not specific to 9pi -- Plan 9 uses the same usb device drivers on
all platforms.
Try forcing the mouse to use the simpler boot protocol, by appending
'kbargs=-b' to the command line in cmdline.txt (on dos partition).
