udev 규칙은 usbtmc에 적용되지 않습니다.

2024-6-10 • tag-icon

나는 이것에 대한 많은 연구를 읽었지만 여전히 udev 규칙을 사용하여 usbtmc 장치를 구성하는 데 어려움을 겪고 있습니다. Raspberry Pi OS 5.15에서 테스트를 실행하고 있습니다. 내 udev 규칙 /etc/udev/rules.d/99-usbtmc.rules은 다음과 같습니다.

SUBSYSTEMS=="usb", ACTION=="add", ATTRS{idVendor}=="F4EC", ATTRS{idProduct}=="EE3A", GROUP="usbtmc", MODE="0660"

장치 권한 오류:

$ ls -l /dev/usbtmc0 
crw------- 1 root root 180, 176 Nov  7 17:38 /dev/usbtmc0

출력은 다음과 같습니다 udevadm info.

$ udevadm info -a /dev/usbtmc0

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.

내 장치가 여전히 루트 그룹을 얻는 이유를 설명해 주시겠습니까? 또한 어떤 규칙이 어떤 장치에 적용되는지 어떻게 알 수 있는지 이해가 되지 않습니다.

ttyUSB에서 비슷한 사례를 찾았습니다.여기하지만 좋은 결과는 없습니다.

감사해요
