Правило udev для устройства usb не работает

К сожалению, мое правило udev не будет работать - я пытаюсь сделать символическую ссылку для определенного USB-устройства. здесь Информация об устройстве:Правило udev для устройства usb не работает

/etc/udev/rules.d# udevadm info --query=all --attribute-walk --name=/dev/ttyUSB1 

Udevadm info starts with the device specified by the devpath and then walks up the chain of parent devices. It prints for every device found, all possible attributes in the udev rules key format. A rule to match, can be composed by the attributes of the device and the attributes from one single parent device.

у вас есть какие-либо подсказки, где может быть моя проблема? Спасибо заранее!

перезагрузкой процесс Udev не делали каких-либо изменений, а также команда тест не соответствует правилам. Однако перезагрузка сделала изменения правильно, поэтому исправление было простой перезагрузкой

Вы заметили, что вы напечатали информацию о /dev/ttyUSB1

Wheareas ошибка утверждает, что не может быть в состоянии открыть /sys/dev/ttyUSB1?

После того, как вас claify, что то, что я рекомендовал бы, во-первых, чтобы проверить, есть ли уже какой-либо процесс, который держит устройство открыто.

Вы можете сделать это, вероятно, с

sudo lsof | grep (your device name here)
