Я хотел бы изменить способ создания устройства в моем Ubuntu 14.10.
Устройство: USB UART
Файл: / dev / ttyUSB0
Есть ли способ узнать, какое правило udev создало это? Или я просто пишу новый и надеюсь на лучшее?

ttyUSB0 looks like the default device the kernel will create if not overridden by a udev rule. so I'd wager that no udev rule is yet resonsibkle for that device .
