Problem with usb serial port - Ubuntu 8.04

On ubuntu 8.04 on my laptop, I downloaded the Arduino software onto my desktop and plugged in a board I just bought. But when I ran the software there are no serial ports recognized. In bash I saw

alan@alan-laptop:~/.arduino$ /dev/ttyUSB0
bash: /dev/ttyUSB0: No such file or directory
alan@alan-laptop:~/.arduino$ /dev/ttyUSB1
bash: /dev/ttyUSB1: No such file or directory

So I followed the procedure given at "Ubuntu USB-Serial port install procedure". Now /dev/ttyUSB0 appears in menu and can be selected. When I tried to upload the blink example to the board I got

avrdude: stk500_getsync(): not in sync: resp=0x01
avrdude: stk500_disable(): protocol error, expect=0x14, resp=0x01

Can anyone suggest what is going wrong?

Thanks

Try pressing the reset 1 second after starting the upload. This sometimes will allow the upload to complete. The sanguino I have requires this to get sketches to load.

be sure that you had remove Braille terminal package already

$sudo apt-get remove brltty

then check availability port dev/ttyUSB* on menu and try upload again

Thanks for the suggestions. I had already removed brtty. I tried pressing the reset but still no joy. All works fine on windows so there must be a problem with the serial driver i am using. Would someone with a system working in ubuntu hardy heron please tell me which driver to use? Thanks
