I am using PL2303 serial driver to connect my usb to serial adapter. The first usb to serial adapter I connect gets a device name of tty.usbserial and I can close and open my sessions multiple times with out any problems. If I connect a second usb to serial adapter while the first usb to serial adapter is still connected it get the name of tty.usbserial3 and every time a close and old session and open a new session on the second usb to serial adapter the device name incumbents to tty.usbserial4 then tty.usbserial5 and so on. This is causing my saved profiles and scripts to fail. Is there any way to make the second usb to serial device name persistent?
