User Manual

Below is a description of how this mechanism works.
For simplicity sake, let’s consider one device model only, let’s say ShuttlePRO v2. (The same
mechanism will work with the ShuttlePRO or the ShuttleXpress.)
If you only have one ShuttlePRO v2 (SP1), the device will be targeted as primary device, no
matter which USB port you plug it in to.
With SP1 plugged in, plug the second ShuttlePRO v2 (SP2) into another USB port. SP2 will be
targeted as the secondary device.
• If you keep the devices plugged in to the same ports, the device targeting won’t change
across computer reboots.
• If you unplug SP2 only, SP1 will be kept as primary device. And when you plug SP2 back
in, SP2 will be set to secondary again.
• If you unplug SP1 only, SP2 will be kept as secondary device. And when you plug SP1
back in, SP1 will be recognized as primary.
• If you unplug both SP1 and SP2, the next time you plug in a ShuttlePRO v2, it will be
tagged as SP1 (primary) or SP2 (secondary), depending on the port you plug it in.
