persistent TTYACM serial port

Postby gdusordet » Sun Apr 10, 2016 10:39 am

Hello,
I had to reset my controller Aeotec Z-Stick Gen5 and now when my DS-716+ restart the serial ports are mess up. It keep changing between /dev/ttyACM0 and /dev/ttyACM1 after each restart of the package Domoticz or Synology machine.
Any idea how to suppress 1 seral port or to assign a specific port to the controller
(example : controller will be always assign to /dev/ttyACM0).

Right now it's on ttyACM0 but it will change after I will restart Synology

root@BG-Station:~# dmesg | grep tty
[ 0.000000] console [ttyS0] enabled
[ 4.990966] serial8250: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A
[ 5.001316] 0000:00:1e.4: ttyS1 at MMIO 0x91615000 (irq = 19) is a 16550A
[ 35.640639] ttyS1 - failed to request DMA
[ 48.770024] cdc_acm 1-2:1.0: ttyACM0: USB ACM device

thanks
G
