I suppose that you are working with telosb/tmotes. On the tmotes there 
is an FTDI's FT232BM USB to Serial converter. It enables to program the 
tmote using a PC USB port as an additional - virtual - COM port (VCP).

The drivers for the FT232BM are included in Linux kernel 2.4.20 or 
greater. Check for a file named ftdi_sio.o (probably under 
/lib/modules/2.6.<version>/kernel/drivers/usb/serial). Plug in a tmote 
and check to see if the right driver was loaded:

$ lsmod | grep ftdi

You should see something like:

  usbserial              33224  1 ftdi_sio
  usbhid                 42752  0
  usbcore               139076  6 
ftdi_sio,usbserial,usbhid,ehci_hcd,uhci_hcd

If the ftdi_sio driver is not loaded when inserting a tmote, you need to 
update your kernel.
*Or* you can download the drivers from the FTDI web site 
http://www.ftdichip.com/Drivers/VCP.htm. Then, to install the ftdi_sio 
driver use the following steps:
1. Create a temporary folder in your linux machine.
    $ cd $HOME
    $ mkdir tmpftdi
    $ cd tmpftdi
    $ wget http://www.ftdichip.com/Drivers/VCP/Linux/ftdi_sio.tar.gz
2. Extract the files from ftdi_sio.tar.gz file to your temporary folder
    $ gunzip ftdi_sio.tar.gz
    $ tar -xvf ftdi_sio.tar
3. Build the driver
    $ make
4. Plug in your ftdi device
5. Check to see if default driver was loaded
    $ lsmod
    you will see ftdi_sio if a driver is loaded
6. Remove the default installed driver
    $ sudo rmmod ftdi_sio
7. Install the newly built driver
    $ sudo insmod ftdi_sio.o


Note that I have not tested this steps because on my system (Ubuntu 
6.06) the VCP worked out of the box.

Hope this helps,
Fabrizio
