1st Thanks Paul.
I tried the use Kwrite but do not know how to use it. I opened up Konsole "joeb bash" and tried the following commands:
lspci -nn
show all the hardware>
00:07.2 USB Controller [0c03] intel corp 82371AB/EB/MB PIIx4 USB [8086:711] rev 02

dmesg :

I see the listing for the
USB 1-1: new full speed USB device using uhci_hcd and address
USB 1-1: configuration #1 chosen from 1 choice
USB 1-1: New USB device found, idVendor=0846, idProduct=7100
USB 1-1: New USB device strings: mfr=1, Product=2, SerialNumber=0
USB 1-1: Product: WN121T v101F
USB 1-1: Manufacture: MARVELL

uname -r
2.6.27-desktop586-0.rc8.2mnb

dmesg | grep firmware
IBM TrackPoint firmware: 0x0e, buttons: 3/3

lsusb
bash: lsusb: command not found

/sbin/lsusb
bash: lsusb: no such file or directory

lsmod
bash: command not found

I am sure the chipset : "marvell wireless device v101f"
