After installing the Linksys Wireless-G USB adapter to my desktop and later rebooting my computer, my firewall indicated that WUSB54Gv4.exe attempted to connect to I went to and it appears to be a site for industrial solvents or lubricants. The IP that my firewall flagged associated with this connection attempt is An Arin search traced it to an APNIC registered IP but no further. This .exe was not located in c:\windows or any subfolder of that. It was initiated from my program files; this is where I would expect it to reside.
