Public bug reported:
I have a laptop with four USB ports. Into one of these ports is plugged
a no-name USB widget with 2 more USB ports, a serial port and a parallel
port; I guess there is a USB hub in there also. Into one of these new
USB ports, I plug a BAFO USB-serial adapter, so there are two USB serial
ports.
When I start the computer, these two serial ports are assigned to
/dev/ttyUSB0 and /dev/ttyUSB1 randomly.
I have a modem connected to one of the adapters. Every time I restart,
it is a hit-and-miss whether I can connect to the internet without
changing a configuration file to point to the other /dev/ttyUSB port.
Windows manages to assign the same com port number to the same USB
serial device. How do I make Ubuntu do the same?
