Не может получить доступ к средству отслеживания gps (чипсет MTK)

Я перестал работать к данным отслеживания доступа, собранным с Transystem iBlue 747. Устройство включается и вероятно распознано (человечность 16.04). Сообщается, что это работает хорошо под человечностью.

Я пытался загрузить дорожки с помощью mtkbabel, но являюсь aked, если устройство включается.

mtkbabel  /dev/ttyACM0 -f test -c
Cannot open /dev/ttyUSB0. Did you switch ON the GPS device?

Никакой успех с bt747 и gpsd, также.

Любые подсказки высоко ценятся. Извините за мои ограниченные навыки. Я был бы очень счастлив, если мы можем избегать использования Windows, так как я недавно протолкнул установку Linux на моей рабочей станции в Университете С наилучшими пожеланиями, jens
