roStorageHotplug

This object provides roStorageAttached messages when storage devices appear and roStorageDetached messages

when storage devices disappear. Currently, only external USB devices are supported, and there is no way to poll for

media.

Object Creation: The roStorageHotplug object is created with no parameters.

CreateObject("roStorageHotplug")

Interfaces: ifSetMessagePort

The ifSetMessagePort interface provides the following:

• SetPort(a As Object)

In order to avoid race conditions at startup, you should check for any storage devices that might have existed prior to the

message port being set. We recommend doing this after the object is created and the message port is set, but before

instructing the script to wait for any events.

Example

Sub Main()

mp = CreateObject("roMessagePort")

sh = CreateObject("roStorageHotplug")

gpio = CreateObject("roControlPort", "brightsign")

sh.SetPort(mp)

gpio.SetPort(mp)
