usb: improve error message to indicate root cause #71

Closed harryhaaren closed 6 years ago

harryhaaren commented 6 years ago

When another (Ctlra based, or otherwise) application already has access to a controller, it is not available for "claiming" in the USB code. Improve the error message to indicate that the root cause is probably that another application is already using the device.
