Der Container läuft mit root-rechten um auf den USB-Port zuzugreifen:
ls -la /dev/ttyUSB0
crw-rw-rw- 1 root root 188, 0 Nov 6 11:19 /dev/ttyUSB0
leider wird beim start des Containers der Port nicht initialisiert.
kann auch mit dem script nicht gestartet werden:
/var/www/html/usb_init.php
sh: 1: usb-devices: not found
sh: 1: hwinfo: not found
PHP Notice: Undefined variable: USB_Devices in /var/www/html/usb_init.php on line 13

PHP Notice: Undefined variable: USB_Regler in /var/www/html/usb_init.php on line 407
PHP Warning: file_get_contents(/sys/firmware/devicetree/base/model): failed to open
stream: No such file or directory in /var/www/html/usb_init.php on line 921
root@takealug-solaranzeige2:/# ls -la /sys/firmware/
total 0
drwxrwxrwt 2 root root 40 Nov 6 20:41 .
dr-xr-xr-x 12 root root 0 Nov 6 20:41 ..
Ein händisches initialisieren des Ports geht danach kann die Serielle am USB mit 2400 Baud angesprochen werden:
stty -F /dev/ttyUSB0 raw speed 2400 cs8 -iexten -echo -echoe -echok -onlcr -hupcl ignbrk time 5
Was stimmt mit meinem Container nicht ???
