Очень много USB устройств

[Евгений Кислов]

Добрый день.
Уточните, что это устройство из себя представляет? Cкиньте ссылку на даташит.
После подключения устройства через хаб выполните команду dmesg, сохраните вывод в текстовом файле и выложите сюда.
Если подключать его напрямую в USB порт СПК - оно появляется в списке?

ВладОвен а что пишет в by-id и в by-path ?

После подключения устройства через хаб выполните команду dmesg, сохраните вывод в текстовом файле и выложите сюда.

[ВладОвен]

ВладОвен а что пишет в by-id и в by-path ?

Я не знаю. Как это узнать?

[melky]

посмотреть в этих папках до и после подключения вашего устройства.
А так же посмотреть как выше писали через dmesg | grep usb

[ 49.041923] cp210x 1-1.2.2:1.0: cp210x converter detected
[ 49.046996] usb 1-1.2.2: cp210x converter now attached to ttyUSB0

Он у вас определился, вероятно один конвертер в него подключен?

Учитывая, что это hub и вы можете подключать конвертеры в разной последовательно, надо сделать символические ссылки через правила udev, привязавшись к появляющимся портам usb 1-1.2.2 или иное...
Если конвертеры будут одинаковые и без серийных номеров надо смотреть разницу при их подключении, чтобы привязка была однозначной.
После привязки у меня, например создаются такие ссылки /dev/mydev/Com1 и не важно куда устройство поселила система на ttyUSB0 или ttyUSB1, для меня это устройство всегда /dev/mydev/Com1

Правда я не знаю, как в таком случае обращаться к порту из CodeSys 3.5 но непосредственно в Linux это работает.

cp210x - а, это у вас и есть конвертер, а не hub, он сел на порт ttyUSB0 то есть обращение к порту /dev/ttyUSB0 или создание под него символической ссылки по правилам, чтобы оно для вас всегда было однозначным

[ВладОвен]

Уточните, что это устройство из себя представляет? Cкиньте ссылку на даташит.
После подключения устройства через хаб выполните команду dmesg, сохраните вывод в текстовом файле и выложите сюда.
Если подключать его напрямую в USB порт СПК - оно появляется в списке?

Это устройство собственной разработки. Но оно использует чип CP210x.
В винде оно видится:

Я отключил устройство от юсб-хаба:

[Евгений Кислов]

Это устройство собственной разработки.

Так и не понял, почему оно должно появиться в списке HID устройств.
https://owen.ru/forum/showthread.php...l=1#post418036

[melky]

Тут наверное Евгений Кислов должен подсказать. Я не работал с CodeSys 3.5 и не знаю, каким способом CodeSys должен видеть порты, подсказал бы иначе.
Символическую ссылку то так и в /dev/input (вместо моего варианта с /dev/mydev) можно сделать если в ПЛК есть udev, а судя по всему он есть. Так же конвертер должен появиться в папке by-path

я не знаю, насколько актуален будет такой подход для ПЛК, просто на Linux можно создавать симлинки на порты.
https://www.blogger.com/blog/post/ed...39968815016413

[ВладОвен]

Учитывая, что это hub и вы можете подключать конвертеры в разной последовательно, надо сделать символические ссылки через правила udev, привязавшись к появляющимся портам usb 1-1.2.2 или иное...

Это открытый вопрос. На Raspberry в CodeSys тоже постоянная путаница с портами. Надо будет в этом серьезно разобраться...

[melky]

ВладОвен путаница происходит из-за очередности подключения, не было портов, подключили первый, он сел на ttyUSB0, второй на ttyUSB1, поменяли очередность подключения или по каким-то причинам произошло отключение порта, он поменяет свою привязку. Первым подключите второе устройство, оно станет ttyUSB0, первое соответственно ttyUSB1.

Вот чтобы от этого уйти, для этого и делается привязка симлинков через правила udev. У меня вопросов с этим больше не возникает
Но там требуется немного разобраться, так как на разных платформах и с разными конвертерами приходится по разному создавать правила.

Хуже всего дешевые конвертеры, так как для системы они полностью одинаковые, привязку делаю по портам самого компьютера. Самое классное, когда у конвертера есть серийный номер, это чипы FTDI, в какой бы порт компьютера не воткнул, всегда можно сделать Com1 например...
