Hi, no suggestion on what it could be, but it looks like you are using the serial device layer, not the libftdi layer.
I'm not sure it will make a difference, or behave more reliable, but you could try to use direct ftdi access, make sure to compile with libftdi support (or if if that is on by default on jessie?) and check the man pages (use something like --device ftdi:xxx:yyyy). Besides that, have you tried pulling the LinkUSB out and re-inserting it (both on USB side and 1W side, if 1W net is externally powered)? And also restarting owserver.
