// Features of the host services device:
|
|
//
|
|
// 1. Vendor-specific mode page 0x20 returns the current date and time, see mode_page_datetime
|
|
//
|
|
// 2. START/STOP UNIT shuts down PiSCSI or shuts down/reboots the Raspberry Pi
|
|
// a) !start && !load (STOP): Shut down PiSCSI
|
|
// b) !start && load (EJECT): Shut down the Raspberry Pi
|
|
// c) start && load (LOAD): Reboot the Raspberry Pi
|
