My observation was wrong. I've pasted `udevmonitor /dev/ttyUSB0` to http://rafb.net/p/CY7p2S91.html and sample code at http://rafb.net/p/OmEu0t95.html in hope it might be of use. When sleep(...) hit, the device file was already away. After a ftdi_usb_find_all(...) it is still there. > > ... > As for the permissions... look at configuration PolicyKit to change > the authorizations for serial modems > ... > -jef > As you suggested, I used PolicyKit to provide direct access to serial modems. Here is my `polkit-auth --user` output: http://rafb.net/p/3dtITs74.html . "org.freedesktop.hal.device-access.modem" is now listed in the output. I tried defining explicitly my user and played with global access options, replugged the device and rebooted. The result is unfortunately still the same: inappropriate permissions on device.
