If it doesn't run reliably, most likely plan9 won't either. And now you can do lsusb -v to see/report details of the connected USB devices. - Get an inexpensive 3.3v UART to USB adapter. This allows you to hook Raspbi's serial console to another machine. On linux you can use mincom or equivalent to connect to the Raspi. This is very handy for debugging.
