I'm suddenly having a problem with my ULN2 being recognized by the Audio Midi Setup in my iMac (Mojave) and with Pro Tools. If I restart my computer it will show up in the list of audio input devices, but when the computer goes to sleep (pt off, of course), I have the same problem. Does anyone have any ideas on what could be causing this problem and how it can be fixed?

Thanks in advance!

I seem to having a similar problem with my ULN-2 3D MIOConsole and Logic Pro on an iMac OS Catalina (all current versions of software).

ULN-2 always stays connected and everything works fine unless iMac goes to sleep. After waking computer up about half the time the ULN-2 is no longer connected. Only solution I've found is to restart everything. Trying to reboot ULN-2 from MIOConsole does not usually fit problem, though it has on a few occasions.

I've also found that sometimes unplugging the Firewire (to Thunderbolt) connection it sometimes shows up on the computer - not fun, but easier than restarting the computer.
