...I wonder if anyone here has come across this before.
Connection :
Mac mini + Intona USB Isolator + Expert Pro 250
When my Expert Pro wakes from sleep, it is not seen by my source (Mac mini + Intona USB Isolator).
When I connect the amp with my mac directly (no isolator) there is no problem.
The only way to fix this is to unplug / replug the isolator. (which is a bit of a pain).
I have contacted the company that makes the isolator, and after running some tests they suggested that it's most probably the USB interface of the amp not handling sleep mode in a USB compliant way, as the isolator seems to work fine with other devices (eg USB discs), when the mac returns from sleep.
