Western Digital My Passport drives have a power-saving function that effectively dismounts the drive from its host.
While this isn’t an issue when connected to a PC/MAC computer (when demanded, the software command spins up the drive) on an audio streaming protocol such as Qu-Drive this makes the drive unavailable.
Most USB-bus powered drives demand a spin-up current from the connection that is at the very least marginal to the 0.5Amp maximum allowed for in the global USB2.0 specification.
The QU-series isn’t unique in falling over with bus-powered mechanical drives. The JoeCo Black Box Recorder devices don’t support ANY bus-powered drive.
I would suggest that you look for an alternative drive that has its own external power supply and NO “sleep” function.
