Hi. I have some problems with USB->Serial FTDI FT232BM chip drivers on
FreeBSD 7.0... FreeBSD recognize the USB device, but when I making
connection to /dev/cuaU0 or /dev/ttyU0 I cant send & receive any data from

cu -l/dev/cuaU0 -s9600 - No response at all, can't even quit the program
cu -l/dev/ttyU0 -s9600 - Sometimes working, but few bites/chars after - no

Sometimes I have error message like: ucom0: open bluk out error (addr 2):
