Wait for usb device

I have an usb contoled powerconnect. So it's possible to start the USB device by starting a program (trueimageservice.exe for example) The problem is that the USB Device needs a few time for start and drive letter assigning. Is it possible to set a time score for a sheduled task to wait for the device Other wise the task is stopping with an error log because usb device missing.

 

Why not schedule a task outside of TrueImage to start the USB drive before TrueImage starts?

TrueImage expects all the drives to be available when it starts. There's no feature to set a delay while drives become available.

 

The usb connect also switch power off when trueimageservice ends with backup. When I do it outside with a sheduled task I have to know how long backup needs. That's not comfortable while I'm using the usb device for several backups over the network.
