Not that anybody is taking requests, but it would be really handy if |
10 |
serial ports were deterministically labeled. |

I ended up having to hack my udev rules to hard-code a symlink a USB |
13 |
serial device to a specific hardware USB port. It has broken once or |
14 |
twice over the years, but has otherwise been reliable. Otherwise, if |
15 |
you have more than one USB serial interface there is no way to know |
16 |
which one will end up with what minor number, which is a bummer if |
17 |
they aren't hooked up to the same thing. |
