Пробовал устройства от ttyUSB0 до ttyUSB7, результат тот же.
Подозреваю, что не хватает некоего модуля ядра, но какого? Подскажите?
Или драйвер USB_ACM не умеет работать с этим устройством, так как в его описании сказано:

If your modem only reports "Cls=ff(vend.)" in the descriptors in
/proc/bus/usb/devices, then your modem will not work with this driver.Спасибо.
