Photon and text mode

If you're using Photon as well as text mode, you won't be able to switch between them and use a USB keyboard once the USB stack has been started.

From a cold boot, you'll be able to use a USB keyboard in text mode before the USB stack has been started. As soon as you start the USB stack, you can't use a USB keyboard in text mode.

Caution: Make sure that the command line for devi-hirun (or Input) includes the option to not reset the keyboard controller. For example:
devi-hirun kbd -R fd -d/dev/usbkbd0 &

Or with QNX 4:

Input kbd -R fd -d/dev/usbkbd0 &

If you don't use the -R option, then the keyboard controller will be reset whenever you switch between Photon and text mode, and the machine may hang.
