Devices for which low latency cannot be set are filtered out so that they do not cause problems later. This can happen if low bit rate serial devices are present in the system along with the AMBE dongles.

This should make the code cleaner and possibly fix any instability

In kernel 4.4.52 the default low latency for FTDI devices was removed. This causes the ThumbDV not to work anymore because the data flow to and from the AMBE3000 chip is made too slow.
This can be fixed by setting low latency via ioctl() and this is fixed in the code this way. Unfortunately this works only for the root user.
Alternatively one may set it up for the life of the /dev/ttyUSB0 device with one of the following commands:
echo 1 | sudo tee /sys/bus/usb-serial/devices/ttyUSB0/latency_timer
sudo setserial /dev/ttyUSB0 low_latency
Of course replace '0' with your device number.

can take values from 0 to 7:
