Hi guys!
For my device control i need to have latency set up into 1,
otherwise i have poor performance.
I can write 1 into /sys/bus/usb_sertial/devices/ttyUSB0/latency_timer,
but only as root, and need to re-write into it after every reconnect device,
that weird.
I have tried to setup udev, by putting into /etc/udev/rules.d/
file z99_ftdi.rules with contents:
DRIVER="ftdi_sio", SUBSYSTEM=="usb-serial", ATTR{latency_timer}="1"
test of rules show that it should correctly write on connection,
but after reconnect of device it doesn't have latency_timer
changed -- it still have 16 latency set :(
Where and what I have missed in rule?

Anton
