Добрый день!
Есть программа gammu-smsd, которая через USB модем отправляет смс.
В настройках программы устанавливаешь, что использовать порт /dev/ttyUSB0. Программа работает и всё нормально. Через какое то время ( компьютер не перегружается никогда и ничего нового не подключается нового), программа сообщает, что по данному порту нет устройства.
Меняешь порт на /dev/ttyUSB1 и всё снова нормально. И так надо периодически туда и сюда менять.
Как решить проблему?
Команда ls /dev/ttyUSB* всегда отдаёт два порта. Это нормально?
ls /dev/ttyUSB*
/dev/ttyUSB0 /dev/ttyUSB1
udevadm info -a -n /dev/ttyUSB0
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.
