 Hello,
 
 Thank you for your replies.
 Yes, in general USB devices work (USB Modem, USB Flash disk, USB HDD). However 
USB subsystem behaves unstable, but it's another issue.
 
 Thank you for your note. Why to use /dev/dtyU*? Is it documented?
 
 When I'm trying to use `cu -s 9600 -l /dev/dtyU0' then I get:
 
 - in dmesg:
 ucom0: detached
 uchcom0: detached
 uchcom0: at uhub3 port 1 (addr 2) disconnected
 
 - in cu:
 FATAL: term closed
 
 - in picocom:
 FATAL: term closed
 term_exitfunc: reset failed for dev UNKNOWN: Bad file descriptor
 
 
 I was trying to look for patches from other BSD:
 - http://svnweb.freebsd.org/base/head/sys/dev/usb/serial/uchcom.c?view=log
 - http://cvsweb.openbsd.org/cgi-bin/cvsweb/src/sys/dev/usb/uchcom.c?f=h
 
 I will try to test other BSD to know whether they will handle my device more 
reliable and back-port patches.
