I have two Serial Bridge connections running. For some reason once in a while I get an error window on the desktop saying one of the USB connections has been disconnected even though no USB connection was manually disconnected. The error below referencing the script file is due to loss of the USB connection. There is no error in the Serial Bridge log. I get this in the console log;

Any ideas appreciated.

The most common cause of this is having the USB adapter plugged into an external USB hub. Hub's will sometimes drop the connection/power to the adapter, which from the OS's perspective means it was momentarily disconnected. Obviously, you can only plug so many USB devices into your Mac itself, so not using a hub may not be an option. I imagine some USB hubs are much more reliably in this regards than others, so I would recommend trying a different brand hub if you cannot plug it directly into your Mac.

Matt,

Ahhh OK, that explains a few things. I'll start looking for a better hub. It's a D-Link DUB-H7 and after your comment it is not recommended.

Maybe I'll do a poll for the best hub.

thanks!
