여기에 게시된 것과 비슷한 문제가 있습니다.이더넷-USB 어댑터가 ttyUSB 또는 ttyACM 장치로 초기화되지 않았습니다.이더넷 USB 어댑터를 통해 Linux 시스템(Ubuntu 14.04.2 Trusty)에 연결된 Geomagic 터치 장치를 연결하려고 합니다. 공급업체에서 제공한 지침에 따라(Linux_helper_notes.pdf)https://3dsystems.teamplatform.com/pages/102863?t=fptvcy2zbkcc)의 경우 해당 장치는 ttyACM 장치로 인식되어야 하는데, 네트워크 장치로 인식됩니다. 지침에 따라 링크 로컬 IPv4로 설정했습니다.
"lsusb -v"의 출력은 다음과 같습니다.
