Re: [sudo-discuss] open thread for update on our door access mechanisms

a really neat thing about linux these days - i don't know if this will work on the pi but when i want to script something involving a USB webcam or a USB serial port, instead of referring to it by /dev/ttyACM0 or whatever, i look for /dev/serial/by-id/usb-Keyspan_**_a_division_of_InnoSys_Inc._** Keyspan_USA-19H-if00-port0 you can put that into your thing instead of /dev/ttyUSB0 or whatever, and it will always work - no matter what order the serial ports come up in. i mean not that you took my advice last time... -jake max klein wrote: keypad update: with new self-healing improvements has just set record uptime at 30 hours. i am monitoring this. the problem is that rpi sometimes chokes and the arduino comes up as a different usb device. so i constantly scan and to find the right usb device. an issue is that the rfid needs to be usb0 so it has to grab that first, and normally does in every instance ive seen it (unless the pyshical usb order gets switched). ______________________________**_________________ sudo-discuss mailing list sudo-discuss(a)lists.sudoroom.**org &lt;sudo-discuss(a)lists.sudoroom.org&gt; http://lists.sudoroom.org/**listinfo/sudo-discuss<http://lists.sudoroom.…
