Hi Andrey,

I try to repeat your cast but no avail.
See my dmesg grep below:
=========================================
voyage:~# dmesg|egrep "ftdi|tty"
[    0.000000] Kernel command line: 
root=UUID=92596085-f0a4-42cf-84ba-d9a03e8e4c00 ro  console=ttyS0,38400n8

voyage:~# ls -la /dev/ttyUSB0
crw-rw---- 1 root dialout 188, 0 Jan  1  2000 /dev/ttyUSB0
=========================================
