Can only upload after plugging in USB

I'm running ubuntu feisty. I have a Diecimila and I'm using the command line tools to upload my sketch.
After I plug-in my arduino, I can upload a sketch just fine by running "make upload". The problem is that if I try to upload another sketch, I get

drock@Outkast:~/projects/Arduino/Fading$ make upload
/usr/bin/avrdude -V -F -C /etc/avrdude.conf -p atmega168 -P /dev/ttyUSB0 -c stk500v1 -b 19200 -U flash:w:applet/Fading.hex
avrdude: stk500_recv(): programmer is not responding
avrdude: stk500_recv(): programmer is not responding
make: *** [upload] Error 1

I have to unplug and plug-in the board to get it upload another sketch. Reset button doesn't seem to help. Unplugging and plugging-in the board every time I make a change to a sketch is getting a little annoying. Anyone got any ideas on how to fix this?

You could try a different usb to serial driver. Might do it.
