Date:		March 2010

Contact:	Bruno Prémont <bonbons@linux-vserver.org>

Description:	Make it possible to switch the PicoLCD device between LCD

		(firmware) and bootloader (flasher) operation modes.



		Reading: returns list of available modes, the active mode being

		enclosed in brackets ('[' and ']')



		Writing: causes operation mode switch. Permitted values are

		the non-active mode names listed when read, optionally followed

		by a delay value expressed in ms.



		Note: when switching mode the current PicoLCD HID device gets

		disconnected and reconnects after above delay (default value

		is 5 seconds though this default should not be relied on).
