4Description: Make it possible to switch the PicoLCD device between LCD
5 (firmware) and bootloader (flasher) operation modes.
6
7 Reading: returns list of available modes, the active mode being
8 enclosed in brackets ('[' and ']')
9
10 Writing: causes operation mode switch. Permitted values are
11 the non-active mode names listed when read, optionally followed
12 by a delay value expressed in ms.
13
14 Note: when switching mode the current PicoLCD HID device gets
15 disconnected and reconnects after above delay (default value
16 is 5 seconds though this default should not be relied on).
