I have a Cocoa app (10.10.4) that needs to connect to two USB devices. For one device, the system will assign it a BSD mount point like “/dev/cu.usbmodem431”, and for the other device, “/dev/cu.usbmodem641”. However, sometimes the number changes, so the 431 will be 471, or the 641 will be 671, etc.
Since the mount point is not fixed, what method can I rely on to determine which device is which? Will the one device always have an enumeration in the 400s, and the other in the 600s, or is this a completely arbitrary number? (It seems not to be arbitrary since the one device always shows up in the 400s and the other always in the 600s, but this seems like a very fragile assumption.) -Carl _______________________________________________ Do not post admin requests to the list.
