USB and serial communication

[Anders Jansson]

Hi everyone,


I have just installed FreeBSD 5.1 om my PC (my first FreeBSD ever and it 
looks really nice).

However, there is one missing link to connect me to FreeBSD heave. I 
would like to have a larger number of serial ports than the 2 already 
aailable in my PC and so I turned my attention to USB. I have a little 
box that has converts one USB connector to 4 serial ports. When I plug 
in this box in one of my two USB connections on my PC, I get the 
following printouts in the /var/log/messages file:


Sep  5 08:05:26 vile kernel: uhub3: Texas Instruments TUSB2046 hub, 
class 9/0, rev 1.10/1.25, addr 2

Furthermore:
bash-2.05b# ls -l /dev/u*

crw-rw----  1 root  operator  108,   2 Sep  5 11:36 /dev/usb2


And finally I try:
bash-2.05b# cu -l ugen0 -s 9600
fcntl: Invalid argument
bash-2.05b#


I have searched the internet for some help on this but I haven't found 
anything useful. I would be most grateful for any kind of assistance.

Cheers
