Raspberry не видит USB модем если он подключен через USB хаб

[pi]

Если подключаю usb модем напрямую то все ОК, он появляется в /dev/ttyUSB[1-3]
Если же я подключаю модем через USB хаб (без разницы с питанием или без), то в /dev/ ничего не появляется.
Кстати если подключаю пустой usb хаб то udevadm monitor начинает бесконечно сыпать такую простыню
